The U.S. Environmental Protection Agency (EPA) has denied 10 petitions challenging its 2009 determination that climate change is real, is occurring due to emissions of greenhouse gases from human activities, and threatens human health and the environment
As soon as the EPA had issued its determination, many a group in America had filed petitions for it to reconsider it. The petitions – filed in by actors as diverse and varied as the Chamber of Commerce, the Ohio Coal Association, the Commonwealth of Virginia – claimed that climate science cannot be trusted, and assert a conspiracy that invalidates the findings of the Intergovernmental Panel on Climate Change (IPCC), the U.S. National Academy of Sciences, and the U.S. Global Change Research Program.
After months of serious consideration of the petitions and of the state of climate change science, EPA finds no evidence to support these claims. In contrast, EPA’s review shows that climate science is credible, compelling, and growing stronger.
“The endangerment finding is based on years of science from the U.S. and around the world. These petitions — based as they are on selectively edited, out-of-context data and a manufactured controversy — provide no evidence to undermine our determination. Excess greenhouse gases are a threat to our health and welfare,” said EPA Administrator Lisa P. Jackson. “Defenders of the status quo will try to slow our efforts to get America running on clean energy. A better solution would be to join the vast majority of the American people who want to see more green jobs, more clean energy innovation and an end to the oil addiction that pollutes our planet and jeopardizes our national security.”
“America’s Climate Choices,” a report from the National Academy of Sciences and the most recent assessment of the full body of scientific literature on climate change, along with the recently released “State of the Climate” report from the National Oceanic and Atmospheric Administration both fully support the conclusion that climate change is real and poses significant risk to human and natural systems. The consistency among these and previously issued assessments only serves to strengthen EPA’s conclusion.
