The endangerment finding that greenhouse gas emissions threaten human health and the environment is based on overwhelming scientific evidence from thousands of expert climate scientists and peer-reviewed studies over decades. Respected scientific bodies like the Intergovernmental Panel on Climate Change, National Academy of Sciences, American Association for the Advancement of Science, and virtually every major scientific organization have confirmed the reality and dangers of human-caused climate change. Revoking this bedrock finding would be an unscientific and dangerous move that ignores the consensus of the global scientific community. It would undermine the EPA's ability to regulate greenhouse gas emissions from vehicles, power plants and other major sources - putting public health and the environment at grave risk. This draft plan prioritizes narrow industry interests over scientific facts and disregards the catastrophic consequences of unchecked climate change like rising seas, stronger storms, heat waves, droughts and ecosystem collapse. I urge you to listen to the overwhelming scientific evidence and expert voices, and reject any attempts to undermine the endangerment finding or repeal vehicle emissions standards. Taking action to rapidly reduce greenhouse gas pollution is crucial to protect current and future generations from climate change's existential threats. The scientific reality demands bold climate leadership, not denial.
