Topic: House Science Committee

During a House Science Committee hearing, a representative points out that U.S. trains contribute a negligible percentage of global CO2. The hosts also discuss a 2024 peer-reviewed paper confirming a "global greening" trend, where increased CO2 levels have led to an expansion of Earth's leaf cover equivalent to 1.4 times the size of the United States.

Michael Mann discussed his testimony before the House Science Committee, where he was the sole witness representing the scientific consensus against three "contrarian" witnesses. Mann criticized the Trump administration, specifically EPA head Scott Pruitt and Secretary of State Rex Tillerson, for their ties to the fossil fuel industry and their rejection of human-caused climate change data.
