World already seeing more dangerous heat days — and it’s just the beginning, study says

A new global climate study warns the world is on track to face nearly two extra months of dangerous “superhot” days each year by 2100 — with poorer nations hit hardest. The analysis, from World Weather Attribution and Climate Central, shows that without the 2015 Paris Agreement, Earth would be heading toward 114 additional deadly hot days annually. Scientists say the deal has made a real difference, but warn that even at current warming levels, millions could suffer from extreme heat, rising deaths, and widespread loss of livelihoods.
