US Supreme Court wrestles with oil companies' bid to scuttle climate lawsuit
The US Supreme Court heard arguments from ExxonMobil and Suncor Energy, appealing a Colorado Supreme Court decision allowing a lawsuit by Boulder officials seeking damages for climate change harms. The oil companies argue that state law cannot regulate global conduct, while Boulder accuses them of misleading the public and driving climate change. The Trump administration supports the companies, citing federal authority over air pollution.
