One of the biggest mysteries surrounding President Donald Trump’s EPA is how it plans to revoke the endangerment finding — the lifeblood of most climate regulations. … Experts said EPA may be betting that it can upend the scientific finding — which paved the way for the nation’s rules on climate pollution on cars, power plants and across other sectors — without taking direct aim at the overwhelming evidence that greenhouse gases are driving up global temperatures. Instead EPA Administrator Lee Zeldin and other officials whom the president tasked in January with undoing the finding could raise questions about whether a sector — or even the whole country — contributes enough climate pollution globally to warrant regulation.
