Trump Revokes Climate Change Basis

The Trump administration has controversially revoked the 2009 scientific finding that greenhouse gases endanger public health, effectively dismantling the legal basis for all U.S. climate regulations under the Clean Air Act. Described by President Trump as "the single largest deregulatory action in American history," this move faces immediate legal challenges and fierce criticism from environmental and health advocates who warn of dirtier air and increased health costs.

The Trump administration has rescinded the 2009 scientific determination that greenhouse gases endanger public health and welfare, effectively removing the legal basis for regulating climate pollution under the Clean Air Act.
This action, described by President Trump as "the single largest deregulatory action in American history," dismantles the foundation for all U.S. climate regulations, as reported by The Washington Post.
Environmental and health advocates have strongly criticized the decision, with many calling it a "betrayal" of the EPA's mission and pledging legal challenges.
The repeal significantly weakens federal climate authority and is expected to lead to dirtier air and higher health costs for communities, according to the provided article and various environmental groups.
The 2009 endangerment finding, which was based on a 2007 Supreme Court ruling, had served as the linchpin for federal greenhouse gas regulations, including emissions standards for vehicles and power plants.
Critics, including former Vice President Al Gore, have condemned the move as "a direct assault on science, knowledge, and public health," prioritizing fossil-fuel profits over American lives, as noted by Autoweek.
The administration argued that the finding drove up energy costs and hampered U.S. energy dominance, while environmental groups predict increased U.S. greenhouse gas emissions and a prolonged ideological rift over climate change.
