Obama’s Biggest Environmental ‘Victory’ Was A Huge Win for Frackers

by Joshua Frank
 
Greenhouse gas emissions are hot news these days — especially in the lead up to an election when candidates, at least those who claim to believe in climate science, vow to do something about the biggest environmental crisis facing our little blue planet: climate change.

In early March of this year, while campaigning in New Hampshire, Obama vowed to end $4 billion in Big Oil and Gas subsidies. “You can either stand up for the oil companies, or you can stand up for the American people,” Obama said to an applauding audience. “You can keep subsidizing a fossil fuel that’s been getting taxpayer dollars for a century, or you can place your bets on a clean-energy future.”

That sounds dandy, but ending subsidies to polluters is only half the battle, and Obama’s idea of a “clean-energy future” is tenuous at best. In an attempt to round up the green vote, which he successfully accomplished, President Obama trumpeted his half-hearted attempt to put the breaks on climate change by tapping energy sources here at home and regulating the industry that’s doing most of the damage. Only days after the president announced he was looking to fast-track the southern portion of the Keystone XL tar sands pipeline, his administration released the first-ever federal standards to limit greenhouse gas emissions from new power plants.

In what’s now become typical Obama fashion, the move was meant to appease environmental critics while at the same time ensure the fossil fuel industry that the so-called New Source Performance Standard would not actually hurt its bottom lines.

Here’s why: the EPA rule would only impact new coal-fired power plants, but only those that break ground in later next year. In all, 15 proposed coal plants in 10 states could be potentially impacted by the rule, even though most are already hung up in court battles. As such, no coal-fired power plants in the United States have broke ground over the past three years and tenacious environmentalists have seen far more victories than defeats when it comes to battling King Coal.

The new greenhouse rule will require fossil fuel-fired electricity generating units to restrict their emissions to 1,000 pounds of carbon dioxide (CO2) per megawatt-hour of electricity produced; a strict standard to be sure, but one that doesn’t come without caveats. All old power plants, some well over 50 years in age, will be exempt entirely from Obama’s greenhouse rule when it comes into effect, despite the fact that these archaic facilities alone account for over 40 percent of carbon emissions in the country. In a nutshell, the biggest coal polluters are being let off the hook altogether.

Five years ago a staggering 151 new coal plants were slated for construction, but with one of the greatest environmental achievements in our history, grassroots activists across the country stopped their development.

Obama is still riding on the coat-tails of these victories, but what’s underlying the greenhouse gas rule is a bit more sinister. As concerns about the impacts of fracking continue to grow, the power plants that burn natural gas extracted through this process of pumping a mix of water, chemicals and sand deep into the earth’s crust, won’t be covered by the rule. Generally, natural gas plants produce less than 900 pounds of CO2 per megawatt-hour. Indeed the limit set by the EPA was not arbitrary; it directly aids and abets the natural gas industry. Obama knows quite well that natural gas is poised to be the fossil fuel of the future and his administration and the EPA are not going to stand in the way of the big boom.

This isn’t to say the effect of natural gas on climate change is benign — far from it. While still producing a large amount of carbon emissions (albeit less than coal), natural gas also spews a whole bunch of methane (natural gas is methane), which is far more potent than CO2 when it comes to the immediate warming of our planet. In fact, it is estimated that methane gas has a global warming potential 25 times that of CO2 (averaged over 100 years). So, in absolute terms, natural gas does contribute substantially to greenhouse gas emissions, and with more production in the works, this contribution is going to grow a lot more in the years to come.

The EPA certainly understands methane is a big contributor to global warming. In an analysis released last year the agency doubled its earlier estimate for the amount of methane that leaks from natural gas wells and pipelines. This leaking is so extensive that it is equal to the annual emissions from over 35 million automobiles. In addition, the EPA reported that the levels of methane release during the fracking of shale gas were actually 9,000 times higher than previously thought.

Methane, unfortunately, is not covered by Obama’s proposed greenhouse gas rule. Perhaps that’s because Obama supports the expansion of natural gas exploration as well as the notion of “safe” fracking — an oxymoron akin to “clean” coal.

“We have a supply of natural gas that can last America nearly one hundred years, and my administration will take every possible action to safely develop this energy,” said President Obama in his last State of the Union address. “The development of natural gas will create jobs and power trucks and factories that are cleaner and cheaper, proving that we don’t have to choose between our environment and our economy … it was public research dollars, over the course of thirty years, that helped develop the technologies to extract all this natural gas out of shale rock.”

The process Obama is touting is the fracking of natural gas and oil from underground geological formations, like the Marcellus Shale on the East Coast. The procedure has been documented in a draft report by the EPA as causing groundwater pollution in Wyoming, yet fracking remains exempt from the Clean Water Act.

As coal becomes a relic of the past in the U.S., natural gas, with fracking as its main source of extraction, is being set up as the fossil fuel of the future, thanks in large part to Obama’s embrace and the EPA’s blind eye. In 2008 the Obama campaign amassed $884,000 from the oil and gas industry. In 2012 that number topped $2 million.

Often seen as a “bridge fuel” from coal toward renewables, natural gas has not come under the same scrutiny as other fossil fuels. Instead natural gas has been seen as a safer, cleaner burning fuel — an improvement over dirty coal. Hence why the EPA continues to punt on proposing regulations on the industry, as it did for a second at the beginning of last April when it delayed the release of rules for the oil and gas industry. If the EPA caves to the natural gas industry, as it will likely continue to do, the majority of existing fracking wells will be exempt from regulation.

Yet, even if fracking wells begin to receive the regulatory oversight they so gravely deserve, the burning of natural gas is not about to come under intensified scrutiny any time soon. On the contrary, as long as the EPA’s attention remains on curbing coal’s carbon footprint, the natural gas industry is sure to benefit and more methane is sure to seep from the depths of Earth. A recent study by tech billionaire Nathan Myhrvold and climate scientist Ken Caldeira argues that shifting to natural gas “cannot substantially reduce the climate risk in the next 100 years.”

Those fighting the frackers ought to expand their focus from fracking’s immediate dangers, which are very real, to natural gas’ long-term impacts on climate change. Even if fracking were to one day be outlawed, as long as natural gas continues to be burned the planet will continue to heat up. In short, natural gas is not a bridge to renewable energy; it’s a bridge to an even more toxic planet.

Heartland Institute Leak Exposes Strategies of Climate Attack Machine

The documents show how groups play up controversy to undermine confidence in well-established scientific findings
Bob Ward | Tuesday, February 21, 2012 | The Guardian/UK

After the leak from the Chicago-based thinkthank the Heartland Institute, much attention is now being focused on the alleged deception used by the water scientist Peter Gleick to obtain the sensitive internal documents.

And while acts of deception cannot be condoned, it is also important to note that the documents obtained by Gleick provide an insight into how some of those groups that are fundamentally opposed to reducing emissions of greenhouse gases attempt to convey the impression that their arguments are founded on science rather than on ideology.


The Heartland Institute states on its website that its mission is "to discover, develop, and promote free-market solutions to social and economic problems", and that the aim of its work on climate change is to promote "market-based, rather than government-based, solutions to environmental problems".

The Institute has been one of the most active lobbyists against policies in the United States to curb emissions, primarily by attempting to undermine confidence in the findings of scientific research that climate change is driven mainly by human activities.

One of the newly released documents shows very clearly how the institute intends to target teachers and schoolchildren with this strategy. It begins by claiming:
"Many people lament the absence of educational material suitable for K-12 [kindergarten to 12th grade] students on global warming that isn't alarmist or overtly political. Heartland has tried to make material available to teachers, but has had only limited success. Principals and teachers are heavily biased toward the alarmist perspective."

The document then suggests that it will pay Dr David Wojick, described as "a consultant with the Office of Scientific and Technical Information at the US Department of Energy in the area of information and communication science", to produce teaching materials which emphasise controversy and uncertainty:
"Wojick would produce modules for Grades 7-9 on environmental impact ("environmental impact is often difficult to determine. For example there is a major controversy over whether or not humans are changing the weather"), for Grade 6 on water resources and weather systems, and so on."

This, of course, is a biased and distorted representation of current scientific knowledge, and conflicts with the approach to school lessons outlined by a recent workshop on climate change education, hosted by the United States National Academy of Sciences, which begins with the statement: "The global scientific and policy community now unequivocally accepts that human activities cause global climate change".

However, the emphasis on uncertainty and controversy is very much in line with another famous leaked document, the so-called Luntz memo, which came to light in 2003. It was prepared by Frank Luntz, the favourite opinion pollster of President George W Bush, and contained advice for Republican activists on how to talk to potential voters about environment issues. On climate change, the memo offers the following recommendation:

"The scientific debate remains open. Voters believe that there is no consensus about global warming within the scientific community. Should the public come to believe that the scientific issues are settled, their views about global warming will change accordingly. Therefore, you need to continue to make the lack of scientific certainty a primary issue in the debate, and defer to scientists and other experts in the field."

The strategy of playing up controversy and uncertainty to undermine confidence in well-established scientific findings was pioneered by the tobacco industry to avoid and delay regulation of its products. As Naomi Oreskes and Erik Conway point out in their book Merchants of Doubt:
"Doubt is crucial to science – in the version we call curiosity or healthy scepticism, it drives science forward – but it also makes science vulnerable to misrepresentation, because it is easy to take uncertainties out of context and create the impression that everything is unresolved. This was the tobacco industry's key insight: that you could use normal scientific uncertainty to undermine the status of actual scientific knowledge."

The Heartland Institute documents also contain details of another activity designed to give its ideological campaign against emissions regulations a veneer of scientific credibility. It notes that the Heartland Institute sponsors the Nongovernmental International Panel on Climate Change (NIPCC), an international network of scientists who write and speak out on climate change.

Again this echoes an approach outlined in the Luntz memo:

"You need to be even more active in recruiting experts who are sympathetic to your view, and much more active in making them part of your message. People are much more willing to trust scientists, engineers, and other leading research professionals, and less willing to trust politicians. If you wish to challenge the prevailing wisdom about global warming, it is more effective to have professionals making the case than politicians."

And it also copies the tactics of cigarette companies which, according to Oreskes and Conway, hired a renowned geneticist in the 1950s to "head the Tobacco Industry Research Committee and spearhead the effort to foster the impression of debate, primarily by promoting the work of scientists whose views might be useful to the industry".

The Heartland Institute documents demonstrate once again how those driven by ideological dogma or vested commercial interests attempt to hide their true motives behind a facade of false controversy and uncertainty in science.

Time to Bury Cap and Trade and Plan Anew

by Jesse Jenkins and Devon SwezeyJuly 26, 2010  | The Breakthrough Institute

Cap and trade is dead. Again. For real this time.

Reports put the time of death at 1 P.M. EST, July 22nd, 2010. That is when Senate Majority Leader Harry Reid emerged from a meeting of the Democratic Caucus without enough support for even a severely weakened and scaled-back emissions cap on the utility sector.

With that, recognition has finally set in everywhere: the United States Senate is not going to enact any form of cap and trade. Not this year. And probably not any time in the foreseeable future.

Worse yet, clean energy progress this year has gone down with the long-sinking cap and trade ship.

Democrats in the Senate have now successfuly wasted what little time they had left on the Congressional calendar wrangling over a utility-only cap--already compromised beyond recognition and destined for political failure--instead of working to advance a package of measures that would have started to make real progress on clean energy.

Reid has made it clear he'll bring only an extremely narrow bill to the floor before the August recess, one pairing measures responding to the Gulf oil spill with some incentives for home efficiency retrofits and natural gas vehicles. That's it. After a full two-year Congressional cycle, Democratic super-majorities, and Barack Obama in the White House: home retrofits and natural gas vehicles are all the Senate will deliver. We should let that sink in for a moment...

Blame Game or Moment of Reflection?

After making his decision to drop cap and trade (and any meaningful clean energy measures with it), Reid wasted no time in pinning the blame on those recalcitrant Republicans, declaring in a statement:
"Many of us want...a comprehensive bill that creates jobs, breaks our addiction to oil and curbs pollution. Unfortunately, at this time not one Republican wants to join us in achieving this goal. That isn't just disappointing. It's dangerous."
Whether it was Republicans, the filibusteroil and coal industry lobbyists or President Obama himself, blame has already been cast far and wide.

But if anything is deserving of blame, it is the cap and trade strategy itself.

Cap and trade has now died four times in the last seven years (this time, we can hope, for good). There is little evidence that Senate Democrats had substantially more votes for cap and trade this year than they did in 2003 (when it failed with 43 votes), 2005 (failed again with 38 votes) or 2008, when Reid also pulled the bill before it could go down in embarrassing defeat and insiders put the final tally at only 35-40 votes in support of the bill.

At this dark moment, the important question is whether any greens or Democrats in Congress are willing to seriously re-think a policy framework that was structurally flawedfrom the beginning and has consistently failed politically.

(Early indications are that they aren't, with Nancy Pelosi saying of the House-passedWaxman-Markey bill, "we're very proud of it and excited to take it to conference.")

The Serial Failure of Cap and Trade

Cap and trade has repeatedly failed because it doesn't address the main barrier to the widespread deployment of clean energy technologies: the technology-based price gap between new clean energy and mature fossil fuels.

Many renewables, like wind and solar power, are expensive, intermittent, and difficult to scale for example, while nuclear power is extremely capital intensive and faces substantial local opposition.

Because of higher costs and technical barriers to widespread clean energy adoption, efforts to move the U.S. energy system away from fossil fuels towards clean energy alternatives inevitably comes with a significant price tag.

The result: every country in the world has been unwilling to raise the price of fossil fuels--either through a carbon tax or a cap and trade system--high enough to close this gap for the majority of clean energy technologies.

The United States is a clear case in point, where the proposed cap and trade bill was riddled with so many loopholes and cost containment mechanisms--most notably the availability of up to 2 billion dubious carbon offsets--that the effective price on carbon wastoo low to effectively spur clean energy innovation and adoption and the "cap" on carbon was rendered effectively non-binding.

But there's another rub. For all the talk about the urgency of a "cap" on emissions in the United States, China has become the world's largest emitter of greenhouse gases and its voracious appetite for energy threatens to wipe out any gains we achieve here in the United States.

China has moved aggressively in recent years to become a leader in the clean energy industry; with timing so perfectly ironic it seems almost planned, China announced last week that the national government would level a staggering $74 billion in annual investments over the next ten years (5 trillion yuan) to adopt clean fuels and build the nation's clean energy industries. But even while establishing itself as the dominant global clean energy power, China's insatiable energy demand is so large that the nation's demand for fossil fuels continues to rise almost unabated.

In the end, until we make clean energy cheap enough to be widely available and affordable throughout the world, countries like China will continue to satisfy the majority of their increasing energy demand with fossil fuels.

Planning Anew for Clean Energy Progress

Given the stakes for both the global climate and the nation's economic outlook, we can't afford yet another episode in the serial failure of the cap and trade strategy.

This moment demands a fundamentally new strategy designed to overcome the inherent political obstacles to carbon pricing and simultaneously achieve the primary objective upon which our climate future hinges: making clean energy cheap in real, unsubsidized terms.

History shows that such technological transformations do not occur through modest shifts in market price signals. We didn't tax the telegraph to get telephones or put a cap on typewriters to see the birth of the personal computer, as Breakthrough's Michael Shellenberger and Ted Nordhaus often note.

Instead, time-and-time again, the most reliably successful driver of new innovation and transformative technology changes has been an active partnership between private-sector entrepreneurs and innovators and a public sector acting as both an initial funder and demanding customer of new, cutting-edge technologies.

This will demand an unprecedented level of public investment in clean energy innovation and the accelerated adoption, scale-up, and improvement of a full suite of clean energy technologies.

Such a strategy can begin to cut U.S. emissions in the near-term, but most importantly it will be absolutely essential to establish the technological and economic foundations for deep emissions cuts in the long term.

As the International Energy Agency has been clear, a global clean energy technology revolution is urgently required, and we have not a moment left to lose.

Without clean, cheap energy, emissions both at home and abroad will continue their inexorable rise, while China and other economic competitors solidify their dominance of new global clean technology markets. With this latest death of cap and trade, will we finally bury a fundamentally flawed strategy and dare to plan (and act!) anew?

Methane levels may see 'runaway' rise, scientists warn

Methane levels may see 'runaway' rise, scientists warn
By Michael McCarthy, Environment Editor

A rapid acceleration may have begun in levels of a gas far more harmful than CO2

Atmospheric levels of methane, the greenhouse gas which is much more powerful than carbon dioxide, have risen significantly for the last three years running, scientists will disclose today - leading to fears that a major global-warming "feedback" is beginning to kick in.

For some time there has been concern that the vast amounts of methane, or "natural gas", locked up in the frozen tundra of the Arctic could be released as the permafrost is melted by global warming. This would give a huge further impetus to climate change, an effect sometimes referred to as "the methane time bomb".

This is because methane (CH4) is even more effective at retaining the Sun's heat in the atmosphere than CO2, the main focus of international climate concern for the last two decades. Over a relatively short period, such as 20 years, CH4 has a global warming potential more than 60 times as powerful as CO2, although it decays more quickly.

Now comes the first news that levels of methane in the atmosphere, which began rising in 2007 when an unprecedented heatwave in the Arctic caused a record shrinking of the sea ice, have continued to rise significantly through 2008 and 2009.

Although researchers cannot yet be certain, and there may be non-threatening explanations, there is a fear that rising temperatures may have started to activate the positive feedback mechanism. This would see higher atmospheric levels of the gas producing more warming, which in turn would release more methane, which would produce even further warming, and so on into an uncontrollable "runaway" warming effect. This is believed to have happened at the end of the last Ice Age, causing a very rapid temperature rise in a matter of decades.

The new figures will be revealed this morning at a major two-day conference on greenhouse gases in the atmosphere, taking place at the Royal Society in London. They will be disclosed in a presentation by Professor Euan Nisbet, of Royal Holloway College of the University of London, and Dr Ed Dlugokencky of the Earth System Research Laboratory in Boulder, Colorado, which is run by the US National Oceanic and Atmospheric Administration (NOAA).

Both men are leading experts on CH4 in the atmosphere, and Dr Dlugokencky in particular, who is in charge of NOAA's global network of methane monitoring stations, is sometimes referred to as "the keeper of the world's methane". In a presentation on "Global atmospheric methane in 2010: budget, changes and dangers", the two scientists will reveal that, after a decade of near-zero growth, "globally averaged atmospheric methane increased by [approximately] 7ppb (parts per billion) per year during 2007 and 2008."

They go on: "During the first half of 2009, globally averaged atmospheric CH4 was [approximately] 7ppb greater than it was in 2008, suggesting that the increase will continue in 2009. There is the potential for increased CH4 emissions from strong positive climate feedbacks in the Arctic where there are unstable stores of carbon in permafrost ... so the causes of these recent increases must be understood."

Professor Nisbet said at the weekend that the new figures did not necessarily mark a new excursion from the trend. "It may just be a couple of years of high growth, and it may drop back to what it was," he said. "But there is a concern that things are beginning to change towards renewed growth from feedbacks."

The product of biological activity by microbes, usually in decaying vegetation or other organic matter, "natural gas" is emitted from natural sources and human activities. Wetlands may give off up to a third of the total amount produced. But large amounts are also released from the production of gas for fuel, and also from agriculture, including the production of rice in paddy fields and the belches of cows as they chew the cud (which is known as "bovine eructation"). However, methane breaks down and disappears from the atmosphere quite quickly, and until recently it was thought that the Earth's methane "budget" was more or less in balance.

Global atmospheric levels of the gas now stand at about 1,790 parts per billion. They began to be measured in 1984, when they stood at about 1,630ppb, and were steadily rising. It was thought that this was due to the Russian gas industry, which before the collapse of the Soviet Union was affected by enormous leaks.

After 1991, substantial amounts were invested in stopping the leaks by a privatised Russian gas industry, and the methane rise slowed.

Methane in the atmosphere: The recent rise

Many climate scientists think that frozen Arctic tundra, like this at Sermermiut in Greenland, is a ticking time bomb in terms of global warming, because it holds vast amounts of methane, an immensely potent greenhouse gas. Over thousands of years the methane has accumulated under the ground at northern latitudes all around the world, and has effectively been taken out of circulation by the permafrost acting as an impermeable lid. But as the permafrost begins to melt in rising temperatures, the lid may open - with potentially catastrophic results.
