The petitions to reconsider EPA's "Endangerment Finding" claim that climate science can't be trusted, and asserted a conspiracy that calls into question 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 found no evidence to support these claims.

Therefore, in its "Denial of Petitions for Reconsideration of the Endangerment and Cause or Contribute Findings for Greenhouse Gases under Section 202(a) of the Clean Air Act", the EPA wrote: "The scientific evidence supporting EPA's finding is robust, voluminous, and compelling. Climate change is happening now, and humans are contributing to it. Multiple lines of evidence show a global warming trend over the past 100 years. Beyond this, melting ice in the Arctic, melting glaciers around the world, increasing ocean temperatures, rising sea levels, altered precipitation patterns, and shifting patterns of ecosystems and wildlife habitats all confirm that our climate is changing."
