'Climate change made killer heat 35x more likely in US'

(UPDATE) WASHINGTON, D.C. — Deadly heat that blanketed the United States, Mexico and Central America recently was made 35 times more likely due to global warming, an international network of climate scientists said on Thursday.

The World Weather Attribution (WWA) group of scientists also said extreme highs witnessed over that region in May and June were four times as likely to occur today as a quarter of a century ago.
