The EPA is headed beyond the pale

As far as where they got those numbers, I suspect that they just made them up.

On Tuesday, Environmental Protection Agency Administrator Lee Zeldin announced a proposal to rescind the agency’s 2009 “endangerment finding,” a critical Obama-era scientific decision about the human health costs of greenhouse gases that allows the EPA to regulate emissions…

In its press release on Tuesday, the EPA said that rolling back the endangerment finding would “undo the underpinning of $1 trillion in costly regulations” and “save more than $54 billion annually” by repealing rules like the Biden administration’s tailpipe emission limits. “With this proposal,” Zeldin said in a statement, “the Trump EPA is proposing to end sixteen years of uncertainty for automakers and American consumers.”

It’s not clear where the agency got these numbers. In 2023, as CNN reported, researchers estimated that climate-driven extreme weather events—which are only expected to get worse—cost the US $150 billion per year. - Mother Jones
