Scientists have known for decades that greenhouse gas emissions from burning fossil fuels create a blanket of pollution that overheats our planet, supercharging extreme weather. We’re seeing this right now in a deluge of summertime climate chaos—deadly flash flooding, heat waves, and wildfires—touching families across the country. That’s why it’s so egregious that the Trump administration is trying to stop EPA’s ability to limit climate pollution. Trump’s EPA Administrator Lee Zeldin has announced a proposal that would rescind the Endangerment Finding, the legal and scientific foundation of EPA’s responsibility to limit greenhouse gas pollution. The proposal also calls for eliminating all limits on climate pollution from vehicle tailpipes, which are one of the largest sources of planet-heating emissions in the U.S. We cannot let this happen. Speak up and tell EPA not to rescind the Endangerment Finding.
