The US Environmental Protection Agency on Tuesday issued a proposal to rescind a foundational scientific finding that underpins the federal government's authority to limit greenhouse gas emissions from motor vehicles and, more broadly, to address climate change. The proposed move is certain to face legal challenges.

Experts warn the move will severely curb the federal government's ability to combat climate change.

EPA\u00a0Administrator Lee Zeldin\u00a0announced the agency's plan to rescind the finding that greenhouse gases endanger public health.
