Mayflower: Deadly Tornado Sweeps Through Arkansas Town That Endured ExxonMobil Tar Sands Pipeline Spill in 2013

On March 29, 2013, ExxonMobil's Pegasus tar sands pipeline ruptured in Mayflower, Arkansas, sending hundreds of thousands of gallons of diluted bitumen (“dilbit”) pouring down the town's streets.

Now, just over a year after the massive spill, devastation has come to Mayflower and neighboring towns again, this time in the form of a lethal tornado. On the evening of April 27, the twister destroyed huge pockets of the town of just over 2,300 citizens in a wholesale manner, with 14 confirmed dead and likely many more still not counted.

“Sadly, we don't expect it to stay at 14,” tweeted Arkansas Governor Mike Beebe. At least 10 died in Faulkner County alone, which houses Mayflower, according to the Arkansas Department of Emergency Management.

The National Weather Service in Little Rock has given the tornado that hit Mayflower an EF-3 rating on a preliminary basis. EF3 (the highest rating is an EF5) equates to 136–165 mile per hour winds and KATV weatherman Todd Yakoubian tweeted that National Weather Service will have its final rating in by April 30.

On the whole, Arkansas Geographic Information Office has reported that 3,200 addresses in Faulkner County have had various levels of impact.

New York Times Joins the Bumbling Keystone XL Cops

This is a guest post by Brad Johnson, cross-posted with permission from Hill Heat.

In a New York Times Earth Day story, the usually excellent Coral Davenport grossly misrepresents the Keystone XL tar-sands pipeline’s true impact on global warming, and questions the wisdom of pipeline opponents like the activists now encamped on the National Mall.

The pipeline is intended to ship upwards of 830,000 barrels of tar-sands crude a day for a 40-year lifespan. The pipeline will add 120-200 million tons of carbon-dioxide-equivalent to the atmosphere annually, with a lifetime footprint of 6 to 8 billion tons CO2e. That’s as much greenhouse pollution as 40 to 50 average U.S. coal-fired power plants. Furthermore the Keystone XL pipeline is recognized by the tar-sands industry as a key spigot for the future development of the Alberta tar sands, which would emit 840 billion tons CO2e if fully exploited.

Interviewing Washington insiders who have offered various forms of support for the Keystone XL project, Davenport claims instead that “Keystone’s political symbolism vastly outweighs its policy substance.” To support the claim, Davenport then erroneously underestimates the global warming footprint of the pipeline by a factor of ten.

Davenport’s crucial error is to contrast the actual carbon footprint of existing fossil-fuel projects — such as US electric power plants (2.8 billion tons) and tailpipe emissions (1.9 billion) — to the impact of the pipeline’s oil being dirtier than traditional petroleum, without explaining that she was switching measurements:

New Study Shows Link Between Climate Change And California Drought

A study published by Geophysical Research Letters sheds new light on the connection between California's epic drought and human-induced climate change.

The study carries the decidedly wonky title, “Probable causes of the abnormal ridge accompanying the 2013-14 California drought: ENSO precursor and anthropogenic warming footprint.”

A subscription is required to read the full thing, but you can read the abstract, which concludes that “there is a traceable anthropogenic warming footprint in the enormous intensity of the anomalous ridge during winter 2013-14, the associated drought and its intensity.”

As the accompanying news release makes clear, this new research not only helps explain how global warming has intensified the drought in the Golden State, but also its role in the record-breaking cold weather that has hit the East Coast. But it's the climate-drought connection that is under the most scrutiny.

Essentially, an “anomalous high-amplitude ridge system,” or a ridge of exceptionally high atmospheric pressure, has contributed to what's known as a “dipole” — in this case, the two poles of the dipole being the high pressure in the Western U.S. and the low pressure in the East.

The researchers, from Utah State University, have “uncovered evidence that can trace the amplification of the dipole to human influences.” They go on to state that “it is important to note that the dipole is projected to intensify, which means more extreme future droughts for California.”

Not everyone accepts the connection between manmade climate change and the Cali drought. To wit, this study is likely to provoke another round in the very public debate between University of Colorado political scientist Roger Pielke, Jr. and Obama Administration Science Advisor Dr. John Holdren.

Responding to Investor Pressure, ExxonMobil Agrees to Disclose Fracking Risks

ExxonMobil, the nation's largest oil and gas company, will begin disclosing risks associated with shale drilling and fracking to investors, in response to a long-running campaign by a coalition of shareholders.

In February, the groups of investors in a handful of major oil and gas companies including Exxon, Chevron and EOG Resources, demanded for the fifth year in a row more information from companies about the risks associated with fracking. The motion won the support of over 30 percent of Exxon shareholders — an unusually strong showing for a shareholder resolution.

On Thursday, the investors’ coalition announced that Exxon was the first company to agree to disclose risks. The company will publish a report by September that will describe fracking’s potential harm to air quality, water and roads, as well as risks associated with the chemicals used. Exxon agreed to follow criteria identified in a 2013 report, cited by the coalition and called Disclosing the Facts: Transparency and Risk in Hydraulic Fracturing Operations, in which Exxon received a failing grade for its transparency.

We have seen the significant risks that come from hydraulic fracturing activities,” said New York City Comptroller Scott M. Stringer, custodian and investment advisor for the New York City Pension Funds’ $144 billion in assets, including $1.02 billion in ExxonMobil stock. “Corporate transparency in this arena is truly necessary for assessing risk and ensuring that all stakeholders have the information they need to make informed decisions.”

However, Exxon’s first report will not disclose data on methane leaks – information that shareholders argued strongly should be made public. Natural gas is primarily made of methane, a potent greenhouse gas that has climate changing effects over 80 times more powerful than carbon dioxide during the first two decades after it escapes to the Earth’s atmosphere.

New IPCC Report: Climate Hazards a “Threat Multiplier” and the World is Not Ready

climate change, IPCC

Human interference with the climate system is occurring, and climate change poses risks for human and natural systems.” IPCC WGII AR5

Every five years or so thousands of scientists from around the world release a major report on the state of climate science. These reports from the Intergovernmental Panel on Climate Change (IPCC) are the most definitive source of information for understanding not only the planet’s geologic and climatic history, but how humans are now influencing earth’s systems, most notably by altering the composition of the atmosphere.

The second part of the most recent report, released today in Yokohama, Japan, focuses on the impacts of climate change and how well governments are adapting to those impacts. This newly-released portion of the report, from the IPCC’s Working Group II, does not bode well for the future of people on this planet. The report predicts massively negative effects on crops, extinction of species, devastating heat waves, acid oceans and geopolitical conflict.

And that’s being called a “conservative” outlook.

FOX Alert: O'Reilly Factor Producer Asks DeSmogBlog to Provide Best Arguments Against Global Warming

Look out, folks. Bill O'Reilly is about to talk about global warming again on the O'Reilly Factor.

Of course, he's already reached his conclusion that “Nobody can control the climate but God.”  It's just that he doesn't have any data to back up his anti-science position. 

So he has one of his producers on the hunt today, apparently scrambling last minute, looking for “the very best arguments” to support climate change denial. Here's the email DeSmogBlog received this morning:   

I feel for O'Reilly's producers, honestly. It must be tough to face this “very tight deadline” problem when asked to provide factual support for a baseless, ideologically-motivated assumption.

Good luck, Robert and friends. It's a difficult job making stuff up so your boss can maintain his politically driven network's ignorance about climate science.  

Who knows, maybe he'll surprise us this time. Stay tuned.

New Study Shows Total North American Methane Leaks Far Worse than EPA Estimates

Just how bad is natural gas for the climate?

A lot worse than previously thought, new research on methane leaks concludes.

Far more natural gas is leaking into the atmosphere nationwide than the Environmental Protection Agency currently estimates, researchers concluded after reviewing more than 200 different studies of natural gas leaks across North America.

The ground-breaking study, published today in the prestigious journal Science, reports that the Environmental Protection Agency has understated how much methane leaks into the atmosphere nationwide by between 25 and 75 percent — meaning that the fuel is far more dangerous for the climate than the Obama administration asserts.

The study, titled “Methane Leakage from North American Natural Gas Systems,” was conducted by a team of 16 researchers from institutions including Stanford University, the Massachusetts Institute of Technology and the Department of Energy’s National Renewable Energy Laboratory, and is making headlines because it finally and definitively shows that natural gas production and development can make natural gas worse than other fossil fuels for the climate.

The research, which was reported in The Washington Post, Bloomberg and The New York Times, was funded by a foundation created by the late George P. Mitchell, the wildcatter who first successfully drilled shale gas, so it would be hard to dismiss it as the work of environmentalists hell-bent on discrediting the oil and gas industry.

Risks of Fracking Boom Draw Renewed Attention from Investors

A coalition of investors called out five oil and gas companies for failing to measure or reduce risks associated with fracking on Tuesday, singling out companies both large and small for how they’ve handled the myriad risks associated with shale oil and gas extraction.

Shareholders in five companies — ExxonMobil, Chevron, EOG Resources, Occidental Petroleum and Pioneer Resources — filed resolutions objecting to the ways that the companies describe the risks of hydraulic fracturing and their failures to reduce the environmental and social impacts of fracking.

“The damaging impacts of hydraulic fracturing on air, water, and local communities have made the public understandably nervous and resistant to permitting this controversial industrial activity,” said Leslie Samuelrich, President of Green Century Capital Management, which together with the New York State Comptroller Thomas DiNapoli, filed the resolution at EOG Resources.

“Companies that fail to demonstrate a public commitment to identifying and mitigating their impacts will fail to earn the public trust,” she added, “and may put shareholder value at risk.”

Four of the five companies – ExxonMobil, Chevron, EOG Resources, and Occidental Petroleum –  received failing scores in a recent report that examined how companies disclosed the impact of fossil fuel extraction and graded their efforts to mitigate risks. Disclosing the Facts: Transparency and Risk in Hydraulic Fracturing Operations focused on 24 companies that use fracking, assessing the ways each handled toxic chemicals, water and waste, air emissions, community impacts, and governance. EOG Resources received a score of 6 out of 32, Chevron a score of 3, ExxonMobil and Occidental Petroleum each got a score of just 2.

That has some investors, including those overseeing New York City’s pension fund, worried.

Keystone XL Decision Highlights Coziness Between Oil and Gas Industry, Obama Administration

This past week was good to the oil and gas industry. First, President Obama talked up jobs gains from drilling and labeled natural gas a “bridge fuel” in his State of the Union address, using terminology favored by natural gas advocates.

Then, on Friday, the Obama administration released a much-awaited assessment of the Keystone XL pipeline’s environmental impacts which concluded that pipeline construction “remains unlikely to  significantly impact the rate of extraction in the oil sands,” effectively turning a blind eye to the staggering carbon emissions from tar sands extraction and expansion plans.

While Mr. Obama’s warm embrace of fossil fuels surprised some environmentalists, it should come as little surprise in light of prior comments made by the CEO of the American Petroleum Institute (API).

“It's our expectation it will be released next week,” Jack Gerard confidently told Reuters, referring to the Keystone XL assessment, while many were still speculating that the report might not be issued until after the November mid-term election. “We're expecting to hear the same conclusion that we've heard four times before: no significant impact on the environment.”

Mr. Gerard added that these predictions were based on sources within the administration.

In fact, as the Keystone decision-making process has unfolded, the oil and gas industry has had — as they’ve enjoyed for decades — intensive access to decision-making in the White House.  This access has helped form the Obama administration’s schizophrenic energy policy, in which the President backs both renewable energy and fossil fuels without acknowledging that the two are competitors. When fossil fuels gain market share, renewables lose.

While even the World Bank has called for immediate action on climate change, the API, which has worked hard to shape Obama’s views on fossil fuels, has also worked to create doubt around the very concept of fossil-fuel-driven climate change and to downplay the impact their industry has had.

There’s no question that the oil and gas industry wields enormous sway inside Washington D.C.

The API has spent $9.3 million dollars this year alone on reportable lobbying expenses, the highest amount in the group’s history, according to data from OpenSecrets.org. This summer, a DeSmog investigation found that API spent $22.03 million dollars lobbying at the federal level on Keystone XL and/or tar sands issues since June 2008, when the pipeline project was first proposed.

Transcript: President Obama's State of the Union Remarks on Energy and Climate Change

President Barack Obama's remarks on energy and climate change during the State of the Union address: (H/T The Guardian)

Now, one of the biggest factors in bringing more jobs back is our commitment to American energy. The all-of-the-above energy strategy I announced a few years ago is working, and today, America is closer to energy independence than we’ve been in decades.

One of the reasons why is natural gas – if extracted safely, it’s the bridge fuel that can power our economy with less of the carbon pollution that causes climate change. Businesses plan to invest almost $100 billion in new factories that use natural gas. I’ll cut red tape to help states get those factories built, and this Congress can help by putting people to work building fueling stations that shift more cars and trucks from foreign oil to American natural gas. My administration will keep working with the industry to sustain production and job growth while strengthening protection of our air, our water, and our communities. And while we’re at it, I’ll use my authority to protect more of our pristine federal lands for future generations.

It’s not just oil and natural gas production that’s booming; we’re becoming a global leader in solar, too. Every four minutes, another American home or business goes solar; every panel pounded into place by a worker whose job can’t be outsourced. Let’s continue that progress with a smarter tax policy that stops giving $4 billion a year to fossil fuel industries that don’t need it, so that we can invest more in fuels of the future that do.
