The Union of Concerned Scientists and a broad coalition of experts argue that the EPA's proposal to repeal the 2009 Endangerment Finding is contrary to scientific evidence and the public interest. They assert that human-caused climate change is indisputable and causes severe harms to public health, the economy, and the environment. The authors specifically criticize the EPA's reliance on a Department of Energy report they describe as unscientific and inaccurate, while urging the agency to maintain regulations on heat-trapping emissions to meet global climate goals.

• The EPA's proposal to repeal the Endangerment Finding relies heavily on a Department of Energy study that the authors characterize as unscientific, inaccurate, and lacking rigorous review.
• Climate change causes severe public health issues, including increased heat-related morbidity and mortality, the spread of infectious diseases, poor air quality, risks to pregnant people and infants, heart and lung diseases, and worsening mental health.
• Climate attribution science now quantifies the contribution of human-caused emissions to specific extreme weather events such as heatwaves, floods, wildfires, and tropical cyclones, as well as ocean acidification and sea level rise.
• Climate change is imposing significant economic costs in the United States, evidenced by rising billion-dollar disasters and threats to household finances and insurance markets, particularly for low-income households.
• The United States is the largest historical contributor and the second largest annual contributor to global heat-trapping emissions, making its national action critical for meeting global climate goals.
