Recalculating the Climate Math
Below is the opening salvo of a new article by the obsessed Bill McKibben. It sounds scientific and hence scary but it is in fact pure theory. There are no new facts behind it at all. The "report" on which Bill relies says this:
"The basic climate science involved is simple: cumulative carbon dioxide (CO2) emissions over time are the key determinant
of how much global warming occurs"
That certainly is simple but there is no proof for it and much to suggest it is wrong. Bill's article is just old stuff in new drag
The future of humanity depends on math. And the numbers in a new study released Thursday are the most ominous yet.
Those numbers spell out, in simple arithmetic, how much of the fossil fuel in the world’s existing coal mines and oil wells we can burn if we want to prevent global warming from cooking the planet. In other words, if our goal is to keep the Earth’s temperature from rising more than two degrees Celsius—the upper limit identified by the nations of the world—how much more new digging and drilling can we do?
Here’s the answer: zero.
That’s right: If we’re serious about preventing catastrophic warming, the new study shows, we can’t dig any new coal mines, drill any new fields, build any more pipelines. Not a single one. We’re done expanding the fossil fuel frontier. Our only hope is a swift, managed decline in the production of all carbon-based energy from the fields we’ve already put in production.
The new numbers are startling. Only four years ago, I wrote an essay called “Global Warming’s Terrifying New Math.” In the piece, I drew on research from a London-based think tank, the Carbon Tracker Initiative. The research showed that the untapped reserves of coal, oil, and gas identified by the world’s fossil fuel industry contained five times more carbon than we can burn if we want to keep from raising the planet’s temperature by more than two degrees Celsius. That is, if energy companies eventually dug up and burned everything they’d laid claim to, the planet would cook five times over. That math kicked off a widespread campaign of divestment from fossil fuel stocks by universities, churches, and foundations. And it’s since become the conventional wisdom: Many central bankers and world leaders now agree that we need to keep the bulk of fossil fuel reserves underground.
But the new new math is even more explosive. It draws on a report by Oil Change International, a Washington-based think tank, using data from the Norwegian energy consultants Rystad. For a fee—$54,000 in this case—Rystad will sell anyone its numbers on the world’s existing fossil fuel sources. Most of the customers are oil companies, investment banks, and government agencies. But OCI wanted the numbers for a different reason: to figure out how close to the edge of catastrophe we’ve already come.
Scientists say that to have even a two-thirds chance of staying below a global increase of two degrees Celsius, we can release 800 gigatons more CO2 into the atmosphere. But the Rystad data shows coal mines and oil and gas wells currently in operation worldwide contain 942 gigatons worth of CO2.

Climate change demands close watch, accurate measures in Arctic
So says Kathryn Sullivan. Fair enough. But why the Arctic only? The Antarctic contains 92% of the word's glacial ice. So isn't it what we should be watching? Would the fact that it is GAINING ice be why the excellent Ms Sulivan is ignoring it? Warmism has an amazing ability to make crooks out of people
In October 1984, I watched the sun illuminate Alaska's Malaspina Glacier from 200 miles above earth. Looking down from the space shuttle Challenger, I was able to fully appreciate the scale and magnitude of a piece of ice 40 miles wide and 28 miles long, roughly 50 times the size of Manhattan Island.
Today's space station astronauts see a very different landscape. Malaspina is melting, just like nearly every other glacier on our planet. Each year the Malaspina and other glaciers in the St. Elias Mountain Range in Southeast Alaska send about 84 gigatons of water into the ocean. That's the equivalent of the approximately 200-mile-long Chesapeake Bay, and it's just a small fraction of the water that is entering the oceans from an unprecedented melting of Arctic ice.
More than anywhere else on Earth, the Arctic has changed dramatically over the past three decades, and there is new urgency in addressing both these changes and their immense global reach. For these reasons, government ministers, scientists, and representatives of indigenous groups from more than 25 nations will hold the first Arctic Science Ministerial on Wednesday at the White House. This meeting is a significant step in recognizing the Arctic as a pivotal, yet vastly underobserved and poorly understood region of our planet.
Concerns around the world are growing because the Arctic's rapid changes are unprecedented. Temperatures are warming at least twice as fast as the global average. Melting ice sheets and glaciers are draining water into the sea at the fastest rate in recorded history, contributing to rising sea levels around the world.

EPA Mandate Created A $1 Billion Market In Fraudulent Biofuel Credits, Says Criminal Investigator
There may be $1 billion worth of fraudulent biofuel credits circulating in the U.S., according to a former Environmental Protection Agency (EPA) criminal investigator.
“Based on my experience, I believe the cost of these fraud schemes to victims and consumers, including taxpayers and obligated parties, is approaching $1 billion,” Doug Parker, the president of E&W Strategies, wrote in a report on biofuel fraud, commissioned by the oil refining Valero Corporation.
Parker, who initiated investigations into biofuel credit fraud while at EPA, argued the federal ethanol mandate, or Renewable Fuel Standard (RFS), is “susceptible to large scale fraud” based on analyses conducted while he worked for the government.
Parker argued RFS fraud risks have grown as the credit, or RIN, market grew 15-fold in the last six years from $1 billion to $15 billion as federal law requires refiners to blend more ethanol into the fuel supply. It’s also an “opaque” market that allows fraud to flourish, he wrote.
“This level of transparency and market regulation is not present in the RINs market, and the opaqueness of the market is a critical factor that allows criminal conduct to continue,” Parker wrote.
Parker argues shifting the “point of obligation” of complying with the RFS from refiners to those further downstream would help reduce the risk of fraud, advocating for a policy being pushed by refiners as part of an effort to reform the RFS.
Refiners are asking EPA to move the onus of complying with the RFS from their industry to those further downstream. Refiners say complying with the RFS cost them $1 billion in 2015, making it one of their largest costs.
Energy experts expect RFS compliance costs to grow as the EPA mandates refiners blend more biofuels into the fuel supply. But ethanol lobbyists say fear of more fraud are overblown, since virtually all of it has taken place in the biodiesel market, not for conventional ethanol-blended gasoline.
“RIN fraud has not been a reality for ethanol used in the RFS program,” Bob Dinneen, president of the Renewable Fuels Association, told The Daily Caller News Foundation.
Parker catalogued $271 million worth of biofuel credit fraud and $71 million in illicit profit seizures by federal agents — all of which has involved biodiesel credits.
“The author is correct that there have been instances of fraud with biodiesel,” Dinneen said. “But those have been successfully prosecuted, and changes to the program put in place to protect against future abuse.”
Dinneen said the report gives a distorted picture of the ethanol market, which has handled more than 90 billion RINs since its inception.
“We do not believe RIN fraud is a legitimate concern,” Dinneen said. “The RFS is and has been a tremendous success for this nation’s energy and economic future, and consumers across the country.”
Even so, Parker says the breaching of the so-called biofuel “blend wall” has opened the door to more fraud as prices increase.
“Investigators and prosecutors are now also seeing evidence of more traditional organized criminal activity in this sector as the frauds have become larger and more complex, Parker wrote.

Big melt of Arctic ice. Big Arctic melts are nothing new
Greenie blindness in Australia
Yesterday I raised the issue of the Greens staging a pre-planned walkout during Pauline Hanson’s first speech last week. The Greens came seriously unstuck. What was obvious to everyone is that the Greens just hate the idea of anyone saying anything to contradict their own twisted view of the world. And why is it that the Greens are so keen to defend Moslems from even gentle criticism?
The Greens are hostile to our Christian civilisation, and they instinctively ally themselves with anyone else who is hostile to Christian civilisation.
Following yesterday’s editorial I received a flood of favourable comment, so here is some more on the same subject.
Pauline Hanson’s Senate speech was bold and courageous in the face of the bland faces of opposition parties who have no stomach for the difficult truths Australia faces in the future. Pauline represents the silent majority who are reluctant to speak out because of our anti-free-speech laws. Many fear retribution from the very people Australia welcomed as citizens and various Muslims openly stating they have no respect for our laws or society and advocating the introduction of sharia law.
It is a sad state of affairs when in the twenty first century human beings have to deal with archaic beliefs supported by embittered people including even deranged individuals with no regard for human life. Australian governments have been asleep at the wheel when it comes to immigration from the third world. One of the main drawcards to Australia is the ridiculous welfare support given to these people. Once in the system they can manipulate and maneuver with many never working in their lifetime getting huge government payments to support their multiple spouses and numerous children. And then they tell us they don’t like us!
As for the Greens, these self-righteous pompous individuals lack the basic common senses to realise their country and their lifestyles are in danger of being hijacked. Open your eyes and ears, read the news occasionally and consider the innocent Australians whose lives have been destroyed by criminals that openly support sharia law and other Islamic militants who exploit Australia’s gullibility. How strange it is that some people still vote for a political party which supports such activity.
Australia is a wonderful country with many beautiful aspects and it should be kept that way. Australians don’t want to live in a lawless society divided by violence and aggression so let’s support the sensible politicians, like Senator Pauline Hanson, The Member for Melbourne Ports Michael Danby MP, Senator Corey Bernardi, Senator Brian Burston, Senator Jacquie Lambie, Senator Bob Day AO and the Federal Member for Dawson in Queensland, George Christensen MP. All of these proudly uphold and support the Australian way of life instead of condoning subversion.
Save Australia before it’s too late!

Green Energy Revolution Folly
President Obama recently set a goal to double renewable power generation in the U.S. by 2020. At the same time, he suggested ending oil company tax breaks and using them, instead, to bolster solar and wind industries. The U.S. government is investing more than $1 trillion in green energy, the so-called "clean" energy alternative, while choking off coal and natural gas production with increasingly onerous regulations.
In their book, Fueling Freedom: Exposing the Mad War on Energy, authors Stephen Moore and Kathleen Hartnett White argue against the shift to renewables. Using energy-production statistics and the historic contributions of fossil fuels, they explode the myths promulgated by renewables cheerleaders. They expose the extensive misinformation on clean energy resources to effectively argue against what they believe would be a disastrous, energy production shift that would have serious lifestyle and geopolitical consequences for Americans.
Promoters of renewable energy sources -- the supposed "low environmental impact" alternative to fossil fuels -- are putting forth a false narrative, Moore and White assert.
Rather than worrying that carbon energy resources are destroying the planet and looking to renewable energy as an alternative, the authors suggest we should celebrate the vast contributions fossil fuels made during the past century, advancing mankind and making our lives safer, more productive and economically and politically secure. The U.S. has more recoverable energy supplies than any nation on earth, the authors posit. With fairly recent shale oil and natural gas discoveries and newer technologies of horizontal drilling and hydraulic fracking, we are in no danger of running out any time soon. It should be welcome news, they urge, that the U.S. can be energy independent within the next few years and be the world's dominant energy producer. Freedom from OPEC manipulations and the potential for millions of jobs that would substantially add to our gross domestic product, benefits our national security and would be a welcome boon to our relatively stagnant economy.
Moore and White explain how the Industrial Revolution, fueled by carbon energy usage, broke through decades of static human existence and brought significant and historic, upward trends for the average person, including a tripling of life expectancy and a 10- to 30-fold increase in per-capita, real income. Coal and petroleum transformed into energy for mechanical power was the most important energy conversion in industrial civilization. With coal-powered machines, man was suddenly liberated from the physical limitations of muscle and beasts of burden. When electricity became available, heat, power and countless household appliances, industrial motors and electronics were developed, generating a second, energy revolution.
Carbon-resource usage (and the invention of the internal combustion engine) brought liberty, mobility and choice, enabling sustained productivity and economic growth, the authors maintain. Additionally, it revolutionized the science and practice of metallurgy and dramatically transformed textile production. Previously expensive and tedious to produce, clothing became more affordable and warmer; winter clothing became available. Today, 60% of global fibers come from fossil fuels. In addition, fossil fuels played and continue to play an important role in reducing food supply loss by refrigeration, packaging and containers.
The authors marvel at the transformation that took place in a newly industrialized society. Until coal was harnessed on a massive scale, humans were dependent on energy from plants, wood, animals and human muscle, as well as wind and water flows. The dramatic shift from diffuse and variable flows of energy -- wind and water -- to massive stores of hydrocarbon minerals was a turning point for human progress. Energy became transportable, controllable, affordable, dense, reliable and versatile.
Fossil fuels have also dramatically benefited agriculture. The authors detail that U.S. food production has tripled, using 1/3 of the land, 1/3 the labor, and at 1/3 the cost of pre-fossil-fuel agriculture. In the past, over 50% of the U.S. population was involved in agriculture and food was scarce and expensive. Today, only 3% of the country's population produces our plentiful food supply.
The economic implications for today's shale revolution are equally extensive, especially if drilling is allowed on federal lands. The authors estimate tax revenues in the trillions of dollars. They cite the economic prosperity of North Dakota, with potentially greater oil resources than Saudi Arabia and currently more millionaires per capita than any other state. The Great Plains state has already surpassed California and Alaska in oil production and is second behind Texas.
The U.S. currently has 50% more oil reserves than in 1950. Technology and innovation have increased our supply so that we discover new sources faster than we deplete known reserves. Further, economic efficiencies in extraction, processing and conversion of energy result in less spending for greater energy output and a continuing reduction in the energy infrastructure physical footprint.
By comparison, non-fossil-fuel energy sources -- wood, wind, solar, hydro, geothermal, biomass and nuclear -make up only 15% of the world's total primary energy supply and provide significantly lower energy yield and potential. For example, the power density -- power per unit of volume -- of natural-gas-fired, electric generation is almost 2,000 times greater than that of wind-generated electricity. Using ethanol produced from corn to power a vehicle's internal combustion system creates a net energy loss when the energy used in planting, fertilizing, harvesting, distilling and transporting is factored in. Further, the diversion of 40% of the U.S. corn crop to ethanol, a less efficient fuel than gasoline, has raised corn prices and prompted more farmers to grow corn instead of other vital crops. Biomass energy production, with its accompanying upticks in tractor and farm vehicle usage and chemicals, reduces the food supply, increases fertilizer and water use, and adds to pollution. Production of wind, solar and biofuels uses thousands more acres of land than coal, natural gas and nuclear power. According to Jess Ausubel,1 an average wind system uses 460 metric tons of steel and 870 cubic meters of concrete per megawatt. In contrast, a natural gas combined cycle plant uses about three metric tons of steel and twenty-seven cubic meters of concrete.
As for carbon dioxide falsely classified as pollutant, Moore and White remind readers of basic eighth grade science: Carbon dioxide is essential to plant life, on which all human and animal lives depend for food. Plants inhale carbon dioxide and exhale oxygen used in human respiration. Commercial greenhouses actually use elevated levels of CO2 to stimulate plant growth and that plant life flourished during past periods of higher CO2 levels.
The authors criticize the misguided trend to replace our fossil-fuel-based, electric system with wind, solar or biomass. They argue that green energy can't compete in a free market without bringing scarcity, economic decline, physical suffering and geopolitical crises. The reliability of renewable energy suffers from weather vagaries whereas coal, natural gas and nuclear power deliver energy precisely as needed.
Moore and White bemoan the political clout of the Environmental Protection Agency and its myriad regulations and question its integrity and usefulness. They assert that emissions actually began to fall in the 1960s, nearly a decade before the establishment of the EPA. During the same time as the EPA's anti-industrial "back to nature" philosophy took root, air quality actually improved despite a doubling of fossil fuel use with an accompanying 200% increase in the GDP.
These improvements came from emission reductions and controls made by private business rather than EPA mandates, the authors maintain. Between 1980 and 2010, airborne sulfur dioxide declined by 89%, carbon monoxide by 82%, nitrogen dioxide by 52%, ozone by 27%, particulate matter by 27% and mercury by 65%. Over the past few decades, tailpipe emissions declined by more than 90% with miles traveled increasing by 180%.
In recent years, a massive, wind and solar renewables program failed miserably in Europe. It caused precipitously higher prices and scarcities, prompting hundreds of thousands of families to turn to wood burning in desperation (thus inflating furniture and paper prices) and spurring construction of new coal plants. The threat of blackouts, unacceptably high utility bills and corporate flight resulting from this renewables program, threatened the very stability of Europe. Citing Europe's dismal example, Moore and White explain that contrary to the popular exaltation of renewables, a prosperous American future will be driven by abundant, reliable and inexpensive fossil fuels.

UK: Hinkley Point: how not to go nuclear
This costly project could set back the energy revolution we need
On Thursday afternoon, I went upstairs, closed the curtains and had a lie down for a while. Something shocking had happened and I needed a few minutes to recover. The traumatic event? I read an article by George Monbiot and largely agreed with it. Truly, a once-in-a-blue-moonbat moment.
It’s not an experience I am accustomed to. Monbiot has for a decade been the most consistent and high-profile proponent of misanthropic environmentalism in the UK. But here we were in agreement: nuclear power is a good idea and we need more of it, but the deal to build Hinkley Point C is a bad one. A really bad one. So bad, in fact, that it could put future governments off the idea of nuclear power for years to come. Yet, after a pause for reconsideration, the UK prime minister, Theresa May, decided last week to give Hinkley Point the green light.
Nuclear power has made a comeback largely because of the obsession with greenhouse-gas emissions. Renewables are still relatively expensive compared with burning fossil fuels (though getting cheaper as technology improves), but they are also intermittent. Solar, obviously, only works during the day and produces less energy when it is cloudy. Wind works both day and night, but only when the wind blows. Renewables are thus both intermittent and unpredictable. As a result, both solar and wind need to be backed up by gas-powered stations – but running such stations on a start-stop basis to fill in the gaps is expensive, too.
Nuclear is comparable with renewables in terms of greenhouse-gas emissions, but it is at least reliable. In fact, since fuel costs are relatively low and capital costs are high, the best thing to do is to run nuclear power stations flat out, providing ‘base load’ to the electricity network. Nuclear isn’t so good at adapting to the ups and downs of electricity demand as gas, but it could still provide a big chunk of Britain’s energy needs.
But building nuclear power stations is an expensive, long-term project – just the kind of thing Britain seems to be bad at. To persuade Électricité de France (EdF) to build Hinkley Point C, the government was forced, to echo a line from Nye Bevan, to stuff their mouths with gold. In the case of Hinkley Point, that meant guaranteeing EdF a high price for the electricity it would produce: £92.50 per megawatt-hour (MWh), index-linked to inflation, plus providing billions in loan guarantees.
Even when the deal was struck, the price for EdF’s electricity looked steep. Now it looks embarrassing. The justification for the price was that gas prices were expected to rise sharply, making the effective subsidy to EdF look relatively small – about £6 billion over the lifetime of the plant. Now, with gas prices having fallen, that subsidy could be as high as £30 billion.
That might be justified for a well-established and reliable technology. But the reactor design proposed by EdF has been around for quite some time – and is still yet to produce any electricity. The first such project, in Finland, commenced in 2005. Between constant design changes, technical problems and difficulties with Finnish regulators, the project has run massively over budget and won’t become operational until at least 2018. Similar problems have dogged the plant in Flamanville in France, started in 2007, which again might only produce power at the end of 2018. But, if anything, the problems at Flamanville are even worse, leading to suggestions that the plant might be scrapped.
And to put the tin lid on things, the Hinkley Point project has put such a strain on EdF’s creaking finances that the plant will now be one-third funded by the Chinese, who signed up on the expectation of being able to build plants of their own at Bradwell and Sizewell in years to come. It was security concerns about this Chinese involvement that apparently led to Theresa May’s decision to review the project. The result has been that the UK government will in future take a stake in such projects to ensure that ownership is fully transparent. In truth, May and her advisers may have been looking for a way out of the deal. In the end, politics prevailed over economics.
To sum up: Hinkley Point C is a power station that the UK government no longer wants to pay for, the French company building it doesn’t want to build, the Chinese partners are only supporting in order to build their own power plants in the future, and which may never get built if the technological and engineering problems can’t be solved. But the UK government doesn’t want to offend the French with Brexit negotiations imminent, nor does it want to annoy the Chinese when trade deals might be needed in the future. The French are desperately trying to save face by refusing to admit that their nuclear technology isn’t going to work. So everyone ploughs on. Politics has trumped common sense.
If our first attempt in decades at building a nuclear plant ends in complete farce – and it is quite possible it will – it would surely make it very difficult to win support for nuclear power plants in the future. Which is very bad news, because nuclear power offers the possibility of producing the huge quantities of energy we need to transform our world. Here’s where I disagree with Monbiot: he wants nuclear power to reduce humanity’s ‘footprint’ on the world; I want nuclear power to create the possibility of massively increasing that footprint. That’s something renewables are unlikely to be able to do in the UK, unless we are prepared to turn our countryside and coastline into an ugly monoculture of wind turbines.
Whether it is the current nuclear-fission technology, thorium-based reactors, new nuclear-waste-gobbling designs or even the holy grail itself – nuclear fusion – it is only such concentrated power sources that could really transform the world. Let’s hope that Hinkley Point C does get built and does produce electricity, as promised. At least we could write it off as an expensive mistake, learn some lessons from the process, and then get on with the job of building cost-effective nuclear stations for the future.

Obama Directs Federal Agencies to Consider Climate Change As a National Security Issue
In a Sept. 21 memo to his department heads, President Obama instructed all federal departments and agencies to consider the impact of climate change on national security.
Obama states that it is the policy of the U.S. government to ensure that current and anticipated impacts of climate change be "identified and considered" in developing national security doctrine, policies and plans.
"Climate change poses a significant and growing threat to national security, both at home and abroad," the memo says. Those threats, according to Obama, include flooding, drought, heat waves, intense precipitation, pest outbreaks, disease, and electricity problems, all of which can "affect economic prosperity, public health and safety, and international stability."
Obama also says those anticipated climate change issues could adversely affect military readiness; negatively affect military facilities and training; increase demands for federal support to civil defense authorities,; and increase the need to maintain international stability and provide humanitarian assistance needs.
He has directed his national security and science/technology chiefs to chair an interagency working group to study climate-related impacts on national security and develop plans to deal with those impacts.
The working group will include high-ranking officials from the Departments of State, Treasury, Defense, Justice, Interior, Agriculture, Commerce, Health and Human Services, Transportation, Energy, Homeland Security, Agency for International Development, NASA, Director of National Intelligence, U.S. Mission to the U.N., Office of Management and Budget, Council on Environmental Quality, Millennium Change Corporation, and "any other agencies or offices as designated by the co-chairs."
Among other things, this bureaucratic working group will "develop recommendations for climate and social science data...that support or should be considered in the development of national security doctrine, policy, and plans."
The working group will create data repositories, climate modeling, and simulation and projection capabilities.
The presidential memo lays out a total 17 action points for the working group, all of them premised on the notion that human-caused climate change is indisputable fact.
The working group has been given 90 days to develop an action plan, which must include "specific objectives, milestones, timelines, and identification of agencies responsible for completion of all actions described therein."
And the working group has 150 days to "develop implementation plans" for the action plans. (Some of those implementation plans may be classified because they deal with national security.)
Section 7 of the presidential memo defines various terms, such as climate, climate change, climate modeling, and "fragility."
"'Fragility' refers to a condition that results from a dysfunctional relationship between state and society and the extent to which that relationship fails to produce policy outcomes that are considered effective or legitimate." (Considered "effective and legitimate" by the government, apparently.)
"'Resilience'" refers to the ability to anticipate, prepare for, and adapt to changing conditions and to withstand, respond to, and recover rapidly from disruptions.

Cutting Through the Doom and Gloom: We’re Nature’s Caretakers, Not Undertakers
One environmentalist says if we want to actually help the planet, we humans need to get over ourselves
Imagine a team of paleontologists eons from now, excavating the remains of ancient life. “Aha!” says one, holding up a finger stained with petroleum grease. “Look here,” says another, brandishing a petrified Coca-Cola bottle. “Yes, this confirms it,” remarks a third, holding up a fossilized chicken bone. “This layer is Anthropocene.”
That’s precisely the scene one group of experts seemed to have in mind at this summer’s meeting of the International Geological Congress. The group’s chair, a professor at the University of Leicester, argued that human beings have so profoundly altered our planet that we have entered a new geologic era. The so-called “Anthropocene,” or “era of man,” will be easy to recognize in future rock layers by its distinctive strata of garbage, radioactive fallout, carbon pollution, and yes—chicken bones. At least, that’s what these scientists claim.
And there’s another marker of the Anthropocene: a so-called “Sixth Extinction.” The current die-off of species at the hands of human beings is so severe, say some scientists, that it’s comparable to the extinction of the dinosaurs and other major die-offs in Earth’s history.
“Nature is dead,” we might paraphrase Nietzsche, “and we have killed her.” But is this bleak picture of our relationship with all other life really accurate? Are we really entering the geologic era of man?
Let’s not flatter ourselves, says environmentalist and author Stewart Brand. In a recent essay at Aeon, Brand argues that notions like the “Anthropocene” and the “sixth extinction” aren’t just wrong. They’re a recipe for panic and paralysis when it comes to protecting our still-beautiful and wild Earth.
“Viewing every conservation issue through the lens of extinction threat is simplistic and usually irrelevant,” Brand writes. “Worse, it introduces an emotional charge that makes the problem seem cosmic and overwhelming rather than local and solvable.”
If doctors talked to their patients the way most environmentalists talk to the public, they’d begin every session by saying, “Well, you’re dying. Let’s see if we can do anything to slow that down a little.”
Brand argues that the “lazy romanticism about impending doom” undergirding notions like the “Anthropocene” and the “sixth extinction” is a “formula for hopelessness,” and therefore, failure.
Instead he offers a dose of reality: Almost all of the most recent extinctions have taken place on tiny ocean islands. And those species, while worth mourning, were of almost no ecological importance to the majority of the planet.
Meanwhile, stories like the recovery of the giant panda, which was recently removed from the endangered species list, show that when we focus on incremental and local solutions, humans can undo much of our own damage.
This idea that nature is “extremely fragile or already hopelessly broken” isn’t remotely the case, Brand writes. Nature is resilient, and if given the chance, it will rebound with remarkable speed.
It turns out our understanding of ourselves and our place in the environment is crucial to preserving that environment. We’re caretakers, not undertakers. And naming geologic eras after ourselves does nothing to preserve or tend the world over which God has placed us as stewards.
Will future paleontologists identify our era by its abundant chicken bones? Well, maybe. But if we cut the doom and gloom and see our relationship with nature accurately, they may just find plentiful evidence of pandas, as well.

Powering countries, empowering people
Affordable energy brings jobs, improved living standards and pursuit of happiness
Paul Driessen
For 16 years, in a scene out of pre-industrial America, Thabo Molubi and his partner made furniture in South Africa’s outback, known locally as the “veld.” Lacking even a stream to turn a water wheel and machinery, they depended solely on hand and foot power. But then an electrical line reached the area.
The two installed lights, and power saws and drills. Their productivity increased fourfold. They hired local workers to make, sell and ship more tables and chairs, of better quality, at higher prices, to local and far away customers. Workers had more money to spend, thereby benefitting still more families.
Living standards climbed, as families bought lights, refrigerators, televisions, computers and other technologies that many Americans and Europeans simply take for granted. The community was propelled into the modern era, entrepreneurial spirits were unleashed, new businesses opened, and newly employed and connected families joined the global economy.
People benefited even on the very edge of the newly electrified area. Bheki Vilakazi opened a small shop so people could charge their cell phones before heading into the veld, where rapid communication can mean life or death in the event of an accident, automobile breakdown or encounter with wild animals.
Two hundred miles away, near Tzaneen, other South African entrepreneurs realized their soil and tropical climate produced superb bananas. After their rural area got electricity, they launched the Du Roi Nursery and banana cloning laboratory, where scientists develop superior quality, disease-free seedlings that are placed in gel in sealed containers and shipped all over Africa and other parts of the world.
Educated in a rural school only through tenth grade, Jane Ramothwala was a hotel maid before becoming a general nursery worker with the company. Over the ensuing decades, she worked hard to learn every facet of business operations, taught herself English, and took adult training and education courses – eventually attaining the position of manager for the company’s plant laboratory.
She now earns five times more than she did previously. During that time, the lab grew from 800,000 plants to 10 million, and today the laboratory, nursery and shipment center provide employment for several college graduates and 45 workers with limited educations. Their lives have been transformed, many have built modern homes, and their children have far brighter futures than anyone could have dreamed of a mere generation ago.
Access to electricity, Jane says, “has had a huge impact on the quality of life for many families in rural parts of Limpopo Province.” It has improved her and her neighbors’ lifestyles, learning opportunities and access to information many times over.
These scenes are being repeated all around the world, from Nigeria and Kenya, to Chile, Peru, China, India, Indonesia and dozens of other countries. Thousands of other communities, millions of other families, want the same opportunities. But for now many must continue to live without electricity, or have it only sporadically and unpredictably a few hours each week.
Across the globe, nearly three billion people – almost half the world’s population – still lack regular, reliable electricity. Nearly 1.3 billion people have no access to electricity.
In sub-Saharan Africa, over 600 million people – almost twice the population of the United States, and 70% of the region’s population – still have no or only limited, sporadic electricity. Over 80% of its inhabitants still relies on wood, dung and charcoal fires for most or all of their heating and cooking needs, resulting in extensive smoke and pollution in their homes and villages.
In India, more than 300 million people (almost as many as in Mexico and the United States) still have no electricity at all; tens of millions more have it only a few hours a day.
Countless people in these communities live in abject poverty, often on just a few dollars a day. Sub-Saharan Africa’s per capita income is roughly $1 per day, Zambia-born economist Dambisa Moyo writes, giving it the highest proportion of poor families in the world.
Mothers in these communities spend hours every day bent over open fires, their babies strapped on their backs, breathing poisonous fumes day after day. Many are struck down by debilitating and often fatal lung diseases. Their homes, schools, shops, clinics and hospitals lack the most rudimentary electricity-based technologies: lights, refrigerators, radios, televisions, computers and safe running water.
Their mud-and-thatch, cinderblock and other traditional houses allow flies and mosquitoes to zoom in, feast on human blood, and infect victims with malaria and other killer diseases. Women and children must walk miles, carrying untreated water that swarms with bacteria and parasites that cause cholera, diarrhea and river blindness. Unrefrigerated food spoils rapidly, causing still more intestinal diseases.
Hundreds of millions get horribly sick and five million die every year from lung and intestinal diseases, due to breathing smoke from open fires and not having refrigeration, clean water and safe food.
When the sun goes down, their lives largely shut down, except to the extent that they can work or study by candlelight, flashlight or kerosene lamp.
The environmental costs are equally high. Rwanda’s gorilla habitats are being turned into charcoal, to fuel cooking fires. In Zambia and elsewhere, entrepreneurs harvest trees by the thousands along highways, turning forest habitats into grasslands, and selling logs to motorists heading back to their non-electrified homes in rural areas and even large sections of cities.
As quickly as rich-country charities hold plant-a-tree fund raisers, people around the world cut trees for essential cooking and heating.
Unless reliable, affordable electricity comes, it will be like this for decades to come. Little by little, acre by acre, forest habitats will become grasslands, or simply be swept away by rains and winds. And people will remain trapped by poverty, misery, disease and premature death.
That unsustainable human and ecological destruction can be reversed, just as it was in the United States. A vital part of the solution is power plants that come equipped with steadily improving pollution controls – and burn coal or natural gas that packs hundreds of times more energy per pound than wood or dung or plant-based biofuels.
“Access to the benefits that come with ample energy trumps concerns about their tiny contribution of greenhouse gas emissions,” New York Times columnist Andrew Revkin observed in his DotEarth blog. Africa sits on vast deposits of coal, natural gas and liquid condensates that are largely ignored or simply burned as unwanted byproducts, as companies produce crude oil. Can someone find a business model that can lead to capturing, instead of flaring, those “orphan fuels,” he wondered.
Ultimately, the energy, environmental, climate change and economic debate is about two things:
Whether the world’s poor will take their rightful places among the Earth’s healthy and prosperous people – or must give up their hopes and dreams, because of misplaced health and environmental concerns.
And whether poor countries, communities and families will determine their own futures – or the decisions will be made for them by politicians and activists who use phony environmental disaster claims to justify treaties, laws, regulations and policies that limit or deny access to dependable, affordable electricity and other modern, life-saving technologies … thereby perpetuating poverty, disease and premature death.

A more moderate version of the usual food panic
They admit that some crops would do better. Their modelling assumes that farmers will continue to do the same thing if their yields decline. They won't. They will plant different strains of their crop to get their yields back up. And for commercial crops there are many cultivars available
As climate change continues to alter our planet, humans will soon be forced to find new ways to feed the growing population.
It’s estimated that the amount of food produced will have to double in order to meet the needs of over nine billion people that could occupy Earth in the next 30 years – but climate change threatens much of the land needed to support these crops.
In a new study, researchers explain which areas are expected to be hit hardest, and reveal the future locations that may become more suitable to host wheat, corn, and rice.
The study found that 43 percent of the world’s corn and roughly a third of all wheat and rice are grown in vulnerable areas, with the worst seen in Sub-Saharan Africa, South America, and the Eastern US.
But, climate change may increase the yield potential of croplands in temperate locations, the researchers say.
This includes western and central Russia, and central Canada.
The areas currently used to grow these crops could suffer major drops in productivity by 2050, according to the study, published in the journal Nature Communications.
To determine this, the researchers combined climate change models with maximum land productivity data, allowing them to estimate the changes that could come in the next few decades.
According to the researchers, the effects will be seen all around the globe, influencing the poorest areas in the world along with developed countries.
The study found that 43 percent of the world’s corn and roughly a third of all wheat and rice (33 percent and 37 percent respectively) are grown in vulnerable areas.
Sub-Saharan Africa, South America, and the Eastern US are expected to experience the most dramatic effects.
But, climate change may increase the yield potential of croplands in temperate locations, the researchers say. This includes western and central Russia, and central Canada.
‘Our model shows that on many areas of land currently used to grow crops, the potential to improve yields is greatly decreased as a result of the effects of climate change,’ says Dr Tom Pugh, lead researcher and University of Birmingham academic.
‘But it raises an interesting opportunity for some countries in temperate areas, where the suitability of climate to grow these major crops is likely to increase over the same time period.’
The researchers also say that highly developed counties may be hit harder by this effect, as they have a much smaller yield gap.
And, they say many other factors will influence future crops as well.
‘Of course, climate is just one factor when looking at the future of global agricultural practices,’ Pugh says.
‘Local factors such as soil quality and water availability also have a very important effect on crop yields in real terms.
‘But production of the world’s three major cereal crops need to keep up with demand, and if we can’t do that by making our existing land more efficient, then the only other option is to increase the amount of land that we use.’

Attributing Louisiana Floods to Global Warming
By PAUL C. "CHIP" KNAPPENBERGER and PATRICK J. MICHAELS
In mid-August a slow moving unnamed tropical system dumped copious amounts of precipitation in the Baton Rouge region of Louisiana. Reports were of some locations receiving over 30 inches of rain during the event. Louisiana’s governor John Bel Edwards called the resultant floods “historic” and “unprecedented.”
Some elements in the media were quick to link in human-caused climate change (just as they are to seemingly every extreme weather event). The New York Times, for example, ran a piece titled “Flooding in the South Looks a Lot Like Climate Change.”
We were equally quick to point out that there was no need to invoke global warming in that the central Gulf Coast is prime country for big rain events and that similar, and even larger, rainfall totals have been racked up there during times when there were far fewer greenhouse gases in the atmosphere—like in 1979 when 45 inches of precipitation fell over Alvin, TX from the slow passage of tropical storm Claudette, or in 1940 when 37.5 in. fell on Miller Island, LA from another stalled unnamed tropical system.
But we suspected that this wouldn’t be the end of it, and we were right.
All the while, an “international partnership” funded in part by the U.S. government (through grants to climate change cheerleader Climate Central), called World Weather Attribution (“international effort designed to sharpen and accelerate the scientific community’s ability to analyze and communicate the possible influence of climate change on extreme-weather events such as storms, floods, heat waves and droughts”) and was fervently working to formally (i.e., through a scientific journal publication) “attribute” the Louisiana rains to climate change.
The results of their efforts were made public a couple of weeks ago in parallel with the submission (we’ll note: not acceptance) of their article to the journal Hydrology and Earth System Science Discussions.
Their “attribution” can well, be attributed, to two factors. First, their finding that there has been a large increase in the observed probability of extreme rainfall along the central Gulf Coast—an increase that they claim can be directly related to the rise in the global (!) average temperature. And second, their finding that basically the single (!) climate model they examined also projects an increase in the probably of heavy rainfall in the region as a result of human-induced climate changes. Add the two together, throw in a splashy press release from a well-funded climate change propaganda machine and headlines like the AP’s “Global warming increased odds for Louisiana downpour” are the result.
As you have probably guessed a closer look finds some major shortcomings to this conclusion.
For example, big rains are part of the region’s history—and most (but not all) are result from meandering tropical weather systems whose progress has been slowed by mid-latitude circulation features. In most cases, the intensity of the tropical system itself (as measured by central pressure or maximum wind speed) is not all that great, but rather the abundant feed of moisture feed from the Gulf of Mexico and slow progress of the storm combine to produce some eye-popping, or rather boot-soaking, precipitation totals. Here is a table of the top 10 rainfall event totals from the passage of tropical systems through the contiguous U.S. since 1921 (note that all are in the Gulf Coast region). Bear in mind that the further you go back in time, the sparser the observed record becomes (which means an increased chance that the highest rainfall amounts are missed). The August 2016 Louisiana event cracks the top 10 as number 10. A truly impressive event—but hardly atypical during the past 100 years.
As the table shows, big events occurred throughout the record. But due to the rare nature of the events as well as the spotty (and changing) observational coverage, doing a formal statistical analysis of frequency changes over time is very challenging. One way to approach it is to use only the stations with the longest period of record—this suffers from missing the biggest totals from the biggest events, but at least it provides some consistency in observational coverage. Using the same set of long-term stations analyzed by the World Weather Attribution group, we plotted the annual maximum precipitation in the station group as a function of time (rather than global average temperature). Figure 1 is our result. We’ll point out that there is not a statistically significant change over time—in other words, the intensity of the most extreme precipitation event each year has not systematically changed in a robust way since 1930. It’s a hard sell link this non-change to human-caused global warming.
Admittedly, there is a positive correlation in these data with the global average surface temperature, but correlation does not imply causation. There is a world of distance between local weather phenomena and global average temperature. In the central Gulf Coast, influential denizens of the climate space, as we’ve discussed, are tropical cyclones—events whose details (frequency, intensity, speed, track, etc.) are highly variable from year to year (decade to decade, century to century) for reasons related to many facets of natural variability. How the complex interplay of these natural influencers may change in a climate warmed by human greenhouse gas emissions is far from certain and can be barely even be speculated upon. For example, the El Niño/La Niña cycle in the central Pacific has been shown to influence Gulf Coast tropical cyclone events, yet the future characteristics of this important factor vary considerably from climate model to climate model and confidence in climate model expectations of future impacts is low according to the U.N. Intergovernmental Panel on Climate Change (IPCC).
Which means that using a single climate model family in an “attribution” study of extreme Gulf Coast rainfall events is a recipe for distortion—at best, a too limited analysis, at worse, a misrepresentation of the bigger picture.
So, instead of the widely advertised combination in which climate models and observations are in strong agreement as to the role of global warming, what we really have is a situation in which the observational analysis and the model analysis are both extremely limited and possibly (probably) unrepresentative of the actual state of affairs.
Therefore, for their overly optimistic view of the validity, applicability, and robustness of their findings that global warming has increased the frequency of extreme precipitation events in central Louisiana, we rate Climate Central’s World Weather Attribution’s degree of spin as “Slightly Soiled” and award them two Spin Cycles.
"Slightly Soiled" = Over-the-top rhetoric. An example is the common meme that some obnoxious weather element is new, thanks to anthropogenic global warming, when it’s in fact as old as the earth. An example would the president’s science advisor John Holdren’s claim the “polar vortex,” a circumpolar westerly wind that separates polar cold from tropical warmth, is a man-made phenomenon. It waves and wiggles all over the place, sometimes over your head, thanks to the fact that the atmosphere behaves like a fluid, complete with waves, eddies, and stalls. It’s been around since the earth first acquired an atmosphere and rotation, somewhere around the beginning of the Book of Genesis. Two spin cycles.

Brown passes cow fart law, compares fighting climate change to building 'Noah's Ark'
California’s Governor Jerry Brown (D) has just signed the first legislation in U.S. history to control cow flatulence as his state's economy suffers from anemic growth and high taxes. The new law would target 'short-lived' greenhouse-gas emissions from dairy cows and landfills.
The new law is part of Brown’s ongoing crusade to fight #Climate Change. Meanwhile, voters are wondering what he is doing to fix the state’s lackluster economy now that this legislative session has officially ended.
The short-lived emissions targeted include methane, refrigerant gases (HFCs), diesel tractor emissions (black carbon), etc. Methane is believed to have a global warming potential 23 times higher than carbon dioxide (CO2). Most modern landfills have vents that capture methane emissions and use the gas to generate electricity or to burn raw sewage.
"When Noah wanted to build his ark,” Brown said at the signing ceremony, “Most of the people laughed at him. We've got to build our ark, too, by stopping [these] dangerous pollutants.” Brown said Senate Bill 1383 will protect people’s health and their lungs, though any correlation to poor health is still being investigated.
Part of the problem, he says, is how cow farts and manure impact the #Environment. Under the new law, “farmers have to cut methane emissions to 40 percent below 2013 levels by 2030.” Because this is California, farmers can get assistance from the $50 million brought in under its stringent carbon tax.
Dairy farmers can use the money to buy technology that burns methane and sell the excess electricity back to power companies. All of which is going to take time as they acclimate to being mini-electrical power generators as well as milk and butter producers.
Called “methane digesters,” this type of technology is very expensive and will be funded by money from the state’s carbon tax and other fees. It also penalizes one industry (dairy) at the expense of another (agriculture), which the latter emits far more methane per acreage.
The California Air Resources Board (CARB) says regulating bovine flatulence can be done by reducing the cows' belching and breaking wind. Others say it’s a way to make favored donors wealthier by rewarding ‘big green.’ Environmental activists have also had a hand in writing the new regulations and hope that tackling these short-lived gases will avert warming long enough for new technologies to be created.
The bill was passed entirely by state Democrats. The current law, however, wasn’t good enough for some anti-fossil fuel activists, who demanded stronger language, more ambitious goals, and not postponing mandates until 2024, which gives farmers time to put in place the new technology.
The National Federation of Independent Businesses wrote in a statement that the “mandated 40 percent reduction in methane and 50 percent reduction in [man-made] black carbon gas” was a “direct assault on California’s dairy industry and will hurt manufacturing.”
The new cow and landfill emission law is also tied to a spending bill for the dairy industry and landfill owners that total $90 million.
California Republicans have denounced the new measures as being onerous, saying they will hurt farmers and other businesses. This new legislation is part of the governor’s far-reaching climate change fight that scientists say will do little to avert warming.

Global warming to trigger financial crisis?
Move over mortgages. There’s now something much, much bigger to worry about, and harder to curtail, and far more likely to cause the next financial crisis: global warming.
That’s the conclusion of a new report published recently by the Bank of Canada.
The report is mainly focused on the reinsurance industry, a shadowy corner of the insurance business, and the fact that what the last financial crisis showed us was that when insurance companies aren’t properly regulated or the risks they take on are poorly understood, the results can be disastrous. On top of that, the report’s authors argue that in an era when climate change is causing natural disasters to be more severe, the risks that reinsurance are taking on could be larger than they appear.
The authors argument focuses on the role of retrocession, which are the risk-sharing arrangements among reinsurers. They are often not fully detailed in insurers accounting statements. “An important feature of the retrocession market is its opacity to both to market participants and regulators,” the report reads, adding that the big problem is that reinsurers often don’t know how much risk or what kinds of risks other insurers or reinsurers are taking on. “It is possible for contagion . . . to occur, in which the losses of one party cascade to others in the network.”
Still, a lot would have to go wrong for a failure in the reinsurance industry to spread to the broader economy. The authors, after running a series of stress tests that evaluate the effect of various scenarios on the industry, argue that the stability of the financial industry appears to fairly robust and that “it would take a catastrophic event larger than any experienced in recent history to result in material failures within the industry.”
Unfortunately for the industry, scientists are predicting that natural disasters, and particularly hurricanes, are going to grow in intensity as the effects of climate change grow. For instance, forecasters are predicting Miami—the twelfth largest metropolitan economy in the United States—will have anywhere from 4 to 8 hurricanes this year. The incidence will only grow over time, as will the chances of unprecedented property damage.
Of course, this is the worst-case scenario, and therefore not the most likely to happen.

Steinem: ‘Forced childbirth is the single biggest cause of global warming’
So abortion will cure global warming?
Gloria Steinem helped Planned Parenthood launch a $12 million fundraising campaign last week by saying “nothing is more important” than expanding abortion and “forced childbirth is the single biggest cause of global warming.”
Speaking to a room of 600 people at a gala celebrating Memphis Planned Parenthood’s 75th anniversary, Steinem said, “Nothing but nothing is more important than ensuring our fundamental right to reproductive freedom,” which is “the principle that government power stops at our skin.”
“Forced childbirth is the single biggest cause of global warming,” Steinem told the crowd.
She also trashed members of the pro-life movement for opposing contraception and sodomy.
“Why is it that the same people who are against birth control and abortion are also against sex between two women or two men?” Steinem asked. It’s because those people “are against any sex that cannot end in reproduction,” she said.
Planned Parenthood Greater Memphis Region told local media they’ve already raised $9.8 million in gifts and pledges. Their $12 million fundraising campaign will fund a second Memphis abortion facility and $1.5 million worth of “education” and “advocacy.”
Half of all funds raised are supposed to go toward “sustainability” to keep the Planned Parenthood’s mission alive “for future generations.”
That’ll be difficult given most of what Planned Parenthood does is abort future generations.

New study undercuts favorite climate myth ‘more CO2 is good for plants’(?)
I have commented on this before but now that The Grauniad has got hold of it, I think I should note it again. The grasses in the Stanford experiment showed little response to enhanced CO2 because the soil in the area was phosphorous deficient -- and that stopped the plants from taking much advantage of the other growth factors. See here. There is nothing in the experiment to upset the thousands of studies that show high levels of CO2 enhancing growth.
And the authors below are confused. In their desperation to show corroboration for the badly implemented Stanford study, they quote a study of corn growth in France. But that study showed an adverse effect of high temperature, not high levels of CO2. So it corroborates nothing. All plants do have a temperature range within which they function best so it is no surprise that the corn cultivars mostly used in France were adversely affected by unusually high temperatures. Corn grows in a lot of quite warm areas in Latin America and India so it is just a matter of choosing the right cultivar for the climate. In some places the optimum temperature for maize (corn) germination is given as 33 degrees C! Toasty!
And the prophecy about wheat yields is just modelling, and we know how good Warmist models are. But wheat cultivars vary too so again the only potential challenge posed by a temperature change as small as one degree would be to choose the right cultivar
And in the grand tradition of Green/Left cherry picking, the crooks below ignore the other effects that a temperature rise would bring -- in particular the larger area that would become available for cropping. Canadian wheat farmers are enormously productive despite farming right up to where the cold limits them. A temperature rise would open up vast new areas of croplands for them -- leading to glut rather than any shortage of grain crops
A new study by scientists at Stanford University, published in the Proceedings of the National Academy of Sciences, tested whether hotter temperatures and higher carbon dioxide levels that we’ll see post-2050 will benefit the kinds of plants that live in California grasslands. They found that carbon dioxide at higher levels than today (400 ppm) did not significantly change plant growth, while higher temperatures had a negative effect.
The oversimplified myth of ‘CO2 is plant food’
Those who benefit from the status quo of burning copious amounts of fossil fuels love to argue that more carbon dioxide in the atmosphere will benefit plant life. It’s a favorite claim of climate contrarians like Matt Ridley and Rupert Murdoch.
It seems like a great counter-argument to the fact that carbon dioxide is a dangerous pollutant – a fact that contrarians often dispute. However, reality is far more complicated than the oversimplification of ‘CO2 is plant food.’ Unlike in the controlled environment of a greenhouse, the increasing greenhouse effect on Earth causes temperatures to rise and the climate to change in various ways that can be bad for plant life. We can’t control all the other variables the way we can in a greenhouse.
So far, as contrarians like Rupert Murdoch love to point out, the plant food effect has won out. Earth has become greener in recent decades (although that trend may now be reversing). The situation is not unlike a human diet – at relatively low calorie levels, more food is beneficial. But as calorie intake continues to rise, at a certain point it’s no longer benefiting the human body. More food is good, but only up to a certain point, as the global obesity epidemic makes clear.
The experiment
The Stanford scientists set up 132 plots of flowers and grass in California and introduced varying levels of carbon dioxide, temperature, water, and nitrogen. The scientists conducted the experiments over 16 growing seasons between 1998 and 2014. They found that only higher nitrogen levels resulted in higher plant productivity, while higher temperatures caused it to decline.
While this experiment was specific to California grasslands, other studies have similarly undermined the ‘more CO2 is great’ myth. For example, a 2012 paper found that higher temperatures are detrimental to French corn yields. While French corn production has increased steadily in recent decades due to a combination of technological improvements and CO2 fertilization (the former far more than the latter), yields have leveled off in recent years, and were particularly low when struck by heat waves.
Another study published in Nature Climate Change last week concluded that higher temperatures will cause wheat production to decline. Just a 1°C rise in global temperature will decrease wheat yields by about 5% (approximately 35 million tons). Climate change is bad news for several of our staple crops.

After Eight Years, Obama's Energy Secretary Visits West Virginia
A visit much earlier in the administration's tenure might have made some difference
Those who lived in or near the southern West Virginia and/or southwest Virginia coalfields during the peak of the coal business in the 1950s and ‘60s know that state and local economies thrived because of the tens of thousands of people employed by mining companies and the dozens of companies that supported the industry.
The Norfolk and Western Railway yard in Bluefield, WV, was always filled with coal cars — many of them full of the world’s most widely used fossil fuel — that were bound for the port in Norfolk, VA, or ready to be unloaded into trucks for delivery. The rest were empty, heading back into the coalfields to be refilled and brought back for distribution.
They remember the bustling downtown that was the financial, shopping and recreational center of the region’s coalfields and Bluefield’s population of well over 20,000 residents during the time of peak coal. These are valued memories of the good times.
Today’s population is half that size, and the rail yard is often empty. To those who have seen firsthand the decline of the industry and its effects on local communities, the industry’s decline is a very real and painful thing.
The decline began with natural technological advances, as mechanization gradually began putting hundreds of miners out of work. Over time other forces developed that affected the industry, including the very recent rise of cheap natural gas. Through all of that, there was always a market for coal.
But the federal government’s assault on coal through excessive environmental regulation, spurred by the hotly debated idea that burning coal pours too much carbon dioxide — a gas essential for life on Earth — into the atmosphere, is the greatest problem. Barack Obama put this attack into high gear. However, today our air is cleaner than it’s been in 100 years, mostly because of evolving technological improvements.
Cloistered away in their comfortable offices in Washington, DC, our public servants frequently have no idea what life is like for those toiling away to pay the taxes that fund their salaries. Perhaps if they got out of Washington more they would understand the problems they create for the people they serve.
This may be the case with Energy Secretary Ernest Moniz, who at the invitation of Sen. Joe Manchin (D-WV) finally visited the state after many invitations over the eight painful years of the Obama administration. But while in the state last week, Moniz suggested there is no war on coal, arguing to the contrary that the Obama administration is working to keep coal as an important part of a low-carbon energy future. He also said that cheap natural gas prices are primarily responsible for coal’s downturn.
The absurd idea that there is no war on coal today would be hilarious if the reality wasn’t so tragic, and the suggestion that the very recent drop in natural gas prices is the principal reason for coal’s decline is simply false.
This general situation was foretold by Barack Obama back in the 2008 campaign. “So, if somebody wants to build a coal plant, they can — it’s just that it will bankrupt them, because they are going to be charged a huge sum for all that greenhouse gas that’s being emitted,” Obama declared.
Assuming that Moniz has the capacity to recognize the misery the administration for which he works has caused for this region or really cares about the people affected by its policies, visiting West Virginia much earlier in the administration’s tenure might have made some difference.
Hillary Clinton is on that same path. While campaigning in Ohio earlier this year, she said, “We’re going to put a lot of coal miners and coal companies out of business.” Trying to make that sound better, she said she favored funding to retrain those put out of work, but she didn’t say what kind of jobs and how many of them are currently waiting for trained workers.
Shortly thereafter, while campaigning in West Virginia, Clinton was asked about that comment by a tearful out-of-work coal miner, to whom she responded that what she meant was that coal job losses will continue. See the difference?
Obama’s energy policy is like putting a square peg in a round hole. If you want to put a square peg in a round hole, take some time and think it through: You should gradually and gently reshape the square peg so it will comfortably and appropriately fit into the round hole. Obama’s method is to place the peg on top of the hole and beat it with a hammer until enough of the corners are destroyed that the peg will go into the hole. And even then, it is a poor fit.
Just as horse-drawn wagons and carriages gave way to motorized vehicles when they came to be, coal’s role as a primary fuel would have changed as better methods evolved. Such a process would have been not only more humane and less destructive but infinitely smarter than what has transpired.
Through the centuries humans solved life’s problems and improved their lives through applied intelligence. Somehow, they managed to do this without Barack Obama and the EPA.

A Climate Plan Many Don't Want to Fund
The United Nations is getting closer to garnering enough participation to officially kick-start last year’s Paris climate agreement. According to the Washington Examiner, “The U.N. is expecting about 20 countries to send their ratification documents in the coming days, with Morocco, which is hosting the next round of meetings on the Paris deal in November, saying it plans to ratify the climate accord Wednesday. Brazil, Mexico and other countries are also expected to ratify the deal during the special Wednesday ceremony at U.N. headquarters in New York during the week-long General Assembly.”
The report explains the significance: “As of [last] week, 27 countries, including the U.S., China and Norway, have ratified the agreement. With [this] week’s moves, it would be close to going into effect, but would be just shy of the 55 countries required, representing 55 percent of the world’s emissions, to enter into full force.” However, the UN’s David Nabarro says he’s “absolutely certain” enough countries will formally join within the next few months.
The future of Obama’s Clean Power Plan — or what the Examiner describes as “the central ingredient in Obama’s plan to meet the Paris agreement’s goal” — is questionable, but even assuming it survives legal challenges, a new poll shows that, though most Americans accept so-called climate change, a large percentage are not at all on board with personally funding a plan to mitigate it. According to the recent survey: “Sixty-five percent of Americans say climate change is a problem the U.S. government should address.” However, “When asked whether they would support a monthly fee on their electric bill to combat climate change, 42 percent of respondents are unwilling to pay even $1.”
Writing in The Wall Street Journal, Sam Ori offers an explanation: “The reality may be that while most Americans see climate change as a collective threat, they don’t see it as a threat to them personally.” Perhaps that’s because the atmospheric in the real world is far less hostile than the outlandish claims people see in the mainstream media. But what Americans know is unequivocally hostile was seen just prior to the UN climate summit last November, when Islamists tore through Paris, killing 130 innocent people. That’s a threat most are willing to fight against with their tax dollars in the form of military prowess, which Barack Obama is working diligently to deplete. He’d rather spend your money on other things. Even if you don’t want to.

History keeps proving prophets of eco-apocalypse wrong
We might as well stop panicking. After all, it isn’t good for our health, and it’s probably too late to panic anyway. The avalanche of eco-cataclysm predictions that have proven to be wrong certainly left an imprint on the public mind.
If we do not reverse global warming by the year 2000, “entire nations could be wiped off the face of the earth by rising sea levels”, warned Noel Brown, a director of the United Nations Environment Programme, in 1989.
It is common cause that sea levels have been rising ever since the start of the Holocene at the end of the last Ice Age, about 11,700 years ago. Throughout the 20th century, tide gauge data has shown this rise to be fairly steady at about 1.5mm/year, and largely unaffected by changes in temperature or atmospheric carbon dioxide levels. Since 1993, satellite altimetry has determined a fairly constant sea level rise of just over 3mm/year. However, it is far from clear whether this represents an acceleration or an artefact of how sea level is measured with respect to surrounding land.
A 2016 paper by Australian scientists Albert Parker and Cliff Ollier suggests that the altimetry record suffers from errors larger than its trends, and “returns a noisy signal so that a +3.2 mm/year trend is only achieved by arbitrary ‘corrections’”.
“We conclude that if the sea levels are only oscillating about constant trends everywhere as suggested by the tide gauges, then the effects of climate change are negligible,” they write, “and the local patterns may be used for local coastal planning without any need of purely speculative global trends based on emission scenarios. Ocean and coastal management should acknowledge all these facts. As the relative rates of rises are stable worldwide, coastal protection should be introduced only where the rate of rise of sea levels as determined from historical data show a tangible short term threat. As the first signs the sea levels will rise catastrophically within a few years are nowhere to be seen, people should start really thinking about the warnings not to demolish everything for a case nobody knows will indeed happen.”
Clearly, history proved Noel Brown wrong.
In 2002, George Monbiot urged the rich to give up meat, fish and dairy, writing: “Within as little as 10 years, the world will be faced with a choice: arable farming either continues to feed the world’s animals or it continues to feed the world’s people. It cannot do both.”
In 2002, 908-million people worldwide suffered hunger. Ten years later, that number had declined to 805-million, according to the UN Food and Agricultural Organisation. Because of continued population growth, this nominal decrease represents a much larger decline in the prevalence of undernourishment, from 18.2% of the world’s population in 2002 to 14.1% in 2012. Hunger remains steadily on the decline. Famines, once so common, are rare nowadays.
Clearly, history proved George Monbiot wrong.
In 2008, the US television channel ABC promoted an apocalyptic “documentary” called Earth 2100, hosted by Bob Woodruff. The film cites a host of scientists, including such perennial alarmists as James Hansen, formerly head of Nasa’s Goddard Institute for Space Science, and John Holdren, the US science czar who in the 1970s thought population control might be necessary to ward off mass starvation (see Prophets of doom in high places).
The show depicts the world at various times in the future, leading up to a collapse of civilisation “within this century, and perhaps your lifetime”. By 2015, it said, agricultural production would be dropping because of rising temperatures and the number of malnourished people “just continually grows”. We’ve already seen that the latter prediction proved to be false. Agricultural output also remains on a strong upward trend worldwide, and most of that is because of rising productivity, and not a rise in land use, irrigation, labour or other capital inputs.
A carton of milk would cost $12.99 by 2015, the film said, and a gallon of fuel would cost over $9. In reality, milk cost $3.39 and fuel cost $2.75 in 2015. Much of New York and surroundings would be inundated by rising sea levels, they said.
Clearly, history proved Bob Woodruff and his famous scientific sources wrong.

Coal still in demand
Some news from Australia
Miner New Hope Group expects a recent lift in coal prices will be sustained and boost its earnings in the current financial year.
Weak global oil and gas prices contributed to a $53.7 million loss for 2015/16 for the Queensland-based company, more than double the $21.8 million loss in the prior year, although costs from a new mine acquisition were also a big driver.
New Hope lost $22.6 million to sliding coal and oil prices and in foreign exchange impacts during the 12 months to July 31, but managing director Shane Stephan says better times are ahead after the Chinese government restricted thermal coal supplies - a move that has driven prices up 40 per cent since the start of July.
"Last year, around 50 per cent of the Australian thermal coal industry was not making cash," Mr Stephan told AAP.
"Most importantly, over 90 per cent of the Chinese domestic thermal coal industry was not making cash. That is simply not sustainable."
He said he expected the better coal prices to hold steady.
"We can't see the Chinese government going backwards from the action they have taken in order to constrain supply," he said.
Japan Taiwan and South Korea were also driving demand for thermal coal, he said, with future opportunities expected in the Philippines, Thailand and Vietnam.
New Hope recorded earnings before interest, tax, depreciation and amortisation (EBITDA) of $81.3 million in 2015/16, down from $132.8 million a year earlier.
In the 12 months to July 31, New Hope's profit before extraordinary items was $5.03 million, down from $51.7 million in 2014/15.
Revenue was up 5.1 per cent at $531.5 million but New Hope's bottom line was hit by $52.1 million in acquisition costs, including costs related to its purchase of a 40 per cent stake in the Bengallla coal mine in NSW.
Mr Stephan said the company was benefiting from firmer prices in the current financial year and from its "well-timed" Bengalla acquisition.
The benchmark Newcastle spot price for coal was $US51 a tonne in March when the Bengalla transaction was completed, he said, and was now $US70 a tonne.
During the five months of New Hope's ownership, Bengalla production contributed 1.5 million tonnes to coal sales and earnings of $21.3 million.
Fat Prophets analyst David Lennox said the group's operational result was solid.
"The balance sheet is reasonable with an operating cash surplus of $61 million which is a good result given the sector has been under considerable price pressure," he said.

CO2-caused global warming, invalidated … conclusively
There's nothing in the data to confirm it and much to contradict it
The US EPA will be shuddering following this research announcement by a large group of scientists and reviewers. The most important assumption in EPA’s CO2 Endangerment Finding has been conclusively invalidated
Research Report Executive Summary
Background
On December 15, 2009, EPA issued its Green House Gas (GHG) Endangerment Finding, which has driven very significant and costly regulations beginning with CO2. Focusing primarily on the time period since 1950, EPA’s Endangerment Finding predicated on Three Lines of Evidence, claims that Higher CO2 Emissions have led to dangerously Higher Global Average Surface Temperatures.
Relevance of this Research
The assumption of the existence of a “Tropical Hot Spot (THS){ is critical to all Three Lines of Evidence in EPA’s GHG/CO2 Endangerment Finding.
Stated simply, first, the THS is claimed to be a fingerprint or signature of atmospheric and Global Average Surface Temperatures (GAST) warming caused by increasing GHG/CO2 concentrations[1]. The proper test for the existence of the THS in the real world is very simple. Are the slopes of the three temperature trend lines (upper & lower troposphere and surface) all positive, statistically significant and do they have the proper top down rank order?
Second, higher atmospheric CO2 and other GHGs concentrations are claimed to have been the primary cause of the claimed record setting GAST over the past 50 plus years.
Third, the THS assumption is imbedded in all of the climate models that EPA still relies upon in its policy analysis supporting, for example, its Clean Power Plan recently put on hold by a Supreme Court Stay. These climate models are also critical to EPA’s Social Cost of Carbon estimates used to justify a multitude of regulations across many U.S. Government agencies.
Objectives of the Research
The objective of this research was to determine whether or not a straightforward application of the proper mathematical methods would support EPA’s basic claim that CO2 is a pollutant. Stated simply, their claim is that GAST is primarily a function of four explanatory variables: Atmospheric CO2 Levels, Solar Activity, Volcanic Activity, and a coupled ocean-atmosphere phenomenon called the El Nino-Southern Oscillation (ENSO.)
The first objective of this research was to determine, based on the very considerable relevant and credible tropical temperature data evidence, whether or not the assumed THS actually exists in the real world.
The second related objective was to determine whether, adjusting ONLY for ENSO impacts, anything at all unusual with the Earth’s temperatures seemed to be occurring in the Tropics, Contiguous U.S. or Globally. It is a well-known meteorological fact that, other things equal, El Ninos lead to a global scale warming and La Ninas a global scale cooling, whose magnitudes are related to their ENSO strengths.
The third objective was to determine whether the rising atmospheric CO2 concentrations alone can be shown to have had a statistically significant impact on the trend slopes of often -publically -quoted temperature data.
It should be noted that in carrying out this research project, every effort was made to minimize complaints that this analysis was performed on so-called “cherry picked temperature data”. To avoid even the appearance of such activity, the authors divided up responsibilities, where Dr. Christy was tasked to provide temperature data sets that he felt were most appropriate and credible for testing the THS as well as the two other EPA Endangerment Finding hypotheses. All told, thirteen temperature time series (9 Tropics, 1 Contiguous U.S. and 3 Global) were analyzed in this research. The econometric analysis was done by Jim Wallace & Associates, LLC, and when completed, cross checked by the two other authors as well as seven reviewers.
Findings of the Research
These analysis results would appear to leave very, very little doubt but that EPA’s claim of a Tropical Hot Spot (THS), caused by rising atmospheric CO2 levels, simply does not exist in the real world. Also critically important, even on an all-other-things-equal basis, this analysis failed to find that the steadily rising Atmospheric CO2 Concentrations have had a statistically significant impact on any of the 13 critically important temperature time series data analyzed.
Thus, the analysis results invalidate each of the Three Lines of Evidence in its CO2 Endangerment Finding. Once EPA s THS assumption is invalidated, it is obvious why the climate models they claim can be relied upon, are also invalid. And, these results clearly demonstrate 13 times in fact that once just the ENSO impacts on temperature data are accounted for, there is no “record setting” warming to be concerned about. In fact, there is no ENSO-Adjusted Warming at all. These natural ENSO impacts are shown in this research to involve both changes in solar activity and the well-known 1977 Pacific Climate Shift.
Moreover, on an all-other-things-equal basis, the research strongly implies that there is no statistically valid proof that past increases in Atmospheric CO2 Concentrations have caused the officially reported rising, even claimed record setting temperatures.
Finally, regarding the credibility of these research findings, the temperature data measurements that were analyzed were taken by many different entities using balloons, satellites, buoys and various land based techniques. Needless to say, if regardless of data source, the results are the same, the analysis findings should be considered highly credible.

“Dakota Access Pipeline” Opponents Deliver Nonsense
Spanning 1,172 miles from North Dakota to Central Illinois, and with a daily carrying capacity of approximately half a million barrels of crude oil, the proposed Dakota Access Pipeline (DAPL) is one of the most significant energy projects underway. It is also one of the most controversial: The $3.8 billion pipeline is the subject of ongoing lawsuits, federal injunctions, and protests. Much of the opposition, unfortunately, rests on misunderstandings about the relative risk posed by the pipeline as well as unlawful tactics by demonstrators, according to Independent Institute Senior Fellow William F. Shughart II.
“Trespassing demonstrators, who have tried to prevent pipeline workers from doing their jobs and at one point caused the closure of a state highway, have gone too far, especially since many of them did not bother to attend public meetings or file comments before DAPL’s construction began,” Shughart writes in a recent op-ed.
Moreover, those demonstrators fail to acknowledge the environmental benefits from the completion of the DAPL. “What the activists apparently fail to grasp,” Shughart continues, “is that the alternative to transporting crude oil by pipeline is shipping it by railcar or over the road—much less safe or environmentally friendly transportation modes.” One can only hope that the ill-informed, ill-mannered protestors run out of gas.

Polar bear tragedy porn dressed up as science features in new BBC Earth video
This new effort by the BBC would make the PR department of the Center for Biological Diversity proud, with it’s prominent use of animal tragedy porn pretending to be science. In contrast, the actual science shows something quite different: though summer sea ice since 2007 has declined to levels not predicted until 2040-2070, there has been virtually no negative impact on polar bear health or survival, a result no one predicted back in 2005.
Bizarrely entitled “A 3-million-year ice age is coming to an end“ (15 September 2016), this slick video pretends it’s promoting the recently released paper by Harry Stern and Kristen Laidre (2016) that got a lot of media attention last week (see here and here).
Who exactly suggested the profound prophesy stated in their chosen title, the BBC Earth folks don’t say: the Stern and Laidre paper certainly does not. And the use of a bear that appears to drown before our eyes is Hollywood-style emotional manipulation. Note the careful use of “might” (above) and “could” (below).
“A 3-million-year ice age is coming to an end : A dramatic animation shows how much of the Arctic sea ice has melted away in the last 35 years. The ice loss poses a terminal threat to polar bears” (15 September 2016, BBC Earth).
That summer ice loss has occurred is not news: this paper simply defines a new standardized method of describing summer sea ice loss across all polar bear habitats. As I pointed out previously, the IUCN Polar Bear Specialist Group (PBSG) added this metric to it’s polar bear status table in early 2015 (more than a year before this paper describing the method was submitted for peer review).

La Niña is on its way
The global cooling weather phenomenon La Niña in the equatorial Pacific is steadily increasing in strength – and the NOAA has not recognized this: NOAA Cancels La Niña Watch While La Niña Conditions Exist.
The NOAA has even removed its “La Niña-Watch” last week from its ENSO weekly reports even though the sea surface temperature anomalies (SSTA) in the main Niño-area 3.4 around August 31 had -0.7 K.
The Southern Oscillation Index (SOI) is considered as the two-month leading indicator for the development of the easterly trade winds at the equatorial Pacific, and thus for the development of the ENSO. The 30-day index shows the difference between the surface atmospheric pressure between Tahiti and Darwin (Australia).
Currently it’s at +10.6 and thus clearly in the La Niña range of over +7 and rising steeply:
The warm surface water of the Pacific is driven westwards topwards Australia, and thus bringing cooler water from the depths to the sea surface: Cold upwelling is created and leads to the La Niña.
The SOI shows a clear La Niña path for at least the coming two months.
The cold upwelling phase can also be seen (at least by most of us) through the measured/calculated subsurface temperatures down to 300m depth at the equatorial Pacific:
Despite these clear indications in both the atmosphere and in the water at the equatorial Pacific region, the ENSO models remain completely in dispute over the development up to November.

New paper finds sea levels rising by at most 1.4mm p.a. or 5.5 inches per century
Are long tide gauge records in the wrong place to measure global mean sea level rise?
P. R. Thompson et al.
Abstract
Ocean dynamics, land motion, and changes in Earth’s gravitational and rotational fields cause local sea level change to deviate from the rate of global mean sea level rise. Here, we use observations and simulations of spatial structure in sea level change to estimate the likelihood that these processes cause sea level trends in the longest and highest-quality tide gauge records to be systematically biased relative to the true global mean rate. The analyzed records have an average 20th century rate of approximately 1.6 mm/yr, but based on the locations of these gauges, we show the simple average underestimates the 20th century global mean rate by 0.1 ± 0.2 mm/yr. Given the distribution of potential sampling biases, we find < 1% probability that observed trends from the longest and highest-quality TG records are consistent with global mean rates less than 1.4 mm/yr.

Is the Arctic sea ice ‘spiral of death’ dead?
This year, as every year, there has been much excitement in the media about ‘catastrophic’ melting of Arctic sea-ice, run-away melting, tipping points, death spirals and “ice-free” summers.
There has been the usual guessing game about when exactly the minimum will / has occurred and what the ice area or extent will be on that day.
Claims of ‘ice-free’ conditions at some time in the summer have been bandied about for years in various forms but as the reality sinks in that it’s not as bad as some had claimed, the dates when this is expected happen have often been pushed out beyond the life expectancy of those making the claims.
The meaning of “ice-free” has also been the subject of some serious goal-post relocation efforts, we are now told that ‘ice-free’ does not actually mean free of ice, it means there will be less than one million square km of ice left.
This special branch of mathematics is apparently based on the axiom that zero = 10 6
The problem with this obsessive focusing on one single data point out of 365, is that there is a lot of short term, weather driven variability that can affect the exact timing and size of the minimum in ice coverage. Since the main interest ( outside maritime navigational requirements ) is the hope to find some indications of long term changes in climate, this is not a very instructive way to use the detailed data available.
There have been three notably low summer minima in recent years: 2007, 2012 and 2016. The 2012 event was the lowest in the satellite record going back to 1979. The other two years tie for second place, meaning the current minimum is indistinguishable from the one which occurred nine years previously and the lowest one lies between the two. This incompatible with claims of run-away melting. This was a reasonable hypothesis and cause for concern in 2007 when the relatively short record could be characterised as an increasing rate of change but this interpretation is not compatible with what has happened since.
