EPA Accused Of Blocking Scientific Advancement of Corexit In BP Cleanup

Oil Spill Eater International (OSEI), through the Gulf Oil Spill Remediation Conference group, issued a press release this week saying that the U.S. Environmental Protection Agency (EPA) effectively blocked or otherwise delayed scientific advancement in the cleanup of the 2010 Gulf of Mexico oil disaster by refusing to acknowledge the toxicity of the oil dispersant Corexit.

According to OSEI, the EPA is guilty of violations to the Clean Water Act because they knowingly used the toxic dispersant instead of opting for cleaner, less toxic methods of oil spill cleanup.

OSEI is actually not off base with their accusations.  Reports from late 2012 revealed that using oil dispersants like Corexit make oil spills less visible, but when combined with the oil, create a mixture that is 52 times more toxic than the oil itself.  The studies revealed that even in small amounts, the combination of oil and Corexit reduced the number of egg hatchings in small marine invertebrates by 50%.  These are small creatures like krill, shrimp, and other crustaceans that form the bottom of the oceanic food pyramid.

Those results were just from small doses of the mixture.  And as I wrote in 2011, the amount of Corexit dumped into the Gulf was anything but “small”:

The Credibility Gap: All Talk and Not Much Action on Climate Change

By Hannah McKinnon, National Program Manager at Environmental Defense.

In last week's State of the Union address, President Obama reiterated his vision for clean energy and urgent action on global warming. With TransCanada’s Keystone XL tar sands pipeline on the frontlines and looking threatened, oil industry supporters are suddenly desperate to look like the environmental and climate risks of the tar sands are under control.
 
But there’s a massive credibility gap as Canada’s contribution to global warming is spiralling out of control, with the reckless expansion of the tar sands.
 
We’ve always believed that actions speak louder than words. So while the oil industry and government embark on a pro-tar sands PR campaign, let’s look at how Canada has behaved on climate action and the environmental risks of the tar sands.

Retreat from Science: Interview with Federal Scientist Peter Ross Part 1 of 2

When the Harper government announced deep funding cuts to science programs across the country, the Institute of Ocean Sciences, one of Canada's largest marine institutes located in Sidney, B.C., was among those research outfits hurt as a result. Lead research scientist Peter Ross is one of more than one thousand Department of Fisheries and Oceans (DFO) employees who discovered their position had been terminated.

Canadian Youth Delegation: Tar Sands Creating "Commitment Issues" for Canada at COP18

Canada's leadership is failing to uphold international commitments to reduce the country's emissions under the United Nations Framework Convention on Climate Change (UNFCCC). This failure on the global stage is the direct result of Canada's domestic policies, according to the Canadian Youth Delegation to COP18's recent report “Commitment Issues.”  

Canada's determination to develop Alberta's tar sands constitutes the nation's primary obstacle to progress on climate action. Bitumen extraction in the region “invalidates Canada's commitment to limit global warming to 2 degrees celsius since pre-industrial times and sets a dangerous global precedent for extreme extraction,” the report states.
 
The Canadian government has participated in several significant international agreements and treaties aimed at reducing global levels of greenhouse gas emissions. Yet, given the country's aggressive oil and gas development, these agreements only serve to highlight Canada's disregard for, rather than participation in, international efforts to prevent dangerous global warming.

Why Climate Deniers Have No Scientific Credibility - In One Pie Chart

This is a guest post by James Lawrence Powell.*

Polls show that many members of the public believe that scientists substantially disagree about human-caused global warming. The gold standard of science is the peer-reviewed literature. If there is disagreement among scientists, based not on opinion but on hard evidence, it will be found in the peer-reviewed literature.

I searched the Web of Science for peer-reviewed scientific articles published between 1 January 1991 and 9 November 2012 that have the keyword phrases “global warming” or “global climate change.” The search produced 13,950 articles. See methodology.

"Stephen Harper Hates Science": Federal Scientists Muzzled to Protect Tar Sands Reputation

The Canadian government is working hard behind the scenes to cover up the negative effects that tar sands extraction is having on the local environment, wildlife, communities and the global climate. According to Access to Information documents obtained by Postmedia's Mike De Souza, the Stephen Harper government has actively suppressed the release of vital information regarding the spread of tar sands contamination by muzzling federal scientists.

The gag order, according to De Souza, came on the heels of a newly researched government report in November 2011 which confirmed the findings of University of Alberta scientists Erin N. Kelly and David Schindler. The scientists discovered concentrations of toxics such as heavy metals were higher near tar sands operations, showing a positive correlation between tar sands activity and the spread of contaminants in the local environment.

The government of Canada and the government of Alberta denied the correlation, saying local waterways tested showed no signs of toxic contamination and reports of mutated and cancerous fish downstream from the tar sands were unfounded.

PBS NewsHour Falls Into “Balance” Trap, Provides Megaphone For Anthony Watts

PBS – the network that conservatives have regularly attacked for “liberal bias” for more than 40 years – finally put that myth to rest tonight by airing a one-sided interview with climate change denier Anthony Watts. The former weatherman-turned business owner and blogger Watts, was given close to ten minutes of uncontested airtime to spout his disinformation about climate change, without any retorts from actual climate scientists.

Update: Forecast The Facts launched a petition calling for PBS Ombudsman Michael Getler to investigate whether the segment met PBS' standards.

Watts freely admitted in the interview that he is not a climate scientist, but said that he has a problem with climate scientists because, as Watts says, they are using “faulty data.”

Watts should know a thing or two about faulty data, as he was recommended to PBS reporter Spencer Michels for an interview by the disinformation specialists at the Heartland Institute.

Here is a brief snip from the PBS Newshour interview:

U.S. Government Significantly Underestimating Costs Of Climate Change And Dirty Energy

A new study released today shows that the U.S. government is using faulty calculations and outdated information to determine the costs of energy and climate change in America. The study was written by Chris Hope from the University of Cambridge and Laurie Johnson of the Natural Resources Defense Council, and published in the Journal of Environmental Studies and Sciences.

Current government models would have us believe that fossil fuels provide the cheapest sources of electricity for the United States, but the new study says that the numbers being used are misleading, as they do not take into account all of the costs, specifically those related to climate change, that these sources of energy carry.

What's The Fracking Problem With Natural Gas?

This is a guest post by David Suzuki with contributions from David Suzuki Foundation Communications Manager Ian Hanington.

At least 38 earthquakes in Northeastern B.C. over the past few years were caused by hydraulic fracturing, commonly called fracking, according to a report by the B.C. Oil and Gas Commission. Studies have found quakes are common in many places where that natural gas extraction process is employed.
 
It’s not unexpected that shooting massive amounts of water, sand and chemicals at high pressure into the earth to shatter shale and release natural gas might shake things up. But earthquakes aren’t the worst problem with fracking.
 
Hydraulic fracturing requires massive amounts of water. Disposing of the toxic wastewater, as well as accidental spills, can contaminate drinking water and harm human health. And pumping wastewater into the ground can further increase earthquake risk. Gas leakage also leads to problems, even causing tap water to become flammable! In some cases, flaming tap water is the result of methane leaks from fracking. And methane is a far more potent greenhouse gas than carbon dioxide!
 
Those are all serious cause for concern—but even they don’t pose the greatest threat from fracking. The biggest issue is that it’s just one more way to continue our destructive addiction to fossil fuels. As easily accessible oil, gas and coal reserves become depleted, corporations have increasingly looked to “unconventional” sources, such as those in the tar sands or under deep water, or embedded in underground shale deposits.
