Trump administration plans to repeal key EPA climate rule, alarming environmentalists.

The Trump administration is planning to repeal the 2009 "endangerment finding," which established that greenhouse gases endanger human health and allowed the EPA to regulate emissions under the Clean Air Act. This move would eliminate the federal government's main tool for combating climate change, affecting regulations on industries like vehicles and power plants. Environmental groups are concerned, arguing that the proposal is legally misguided and could harm public health.
