Scary September heat

Axios -  Even by the standards of a sizzling summer, September's temperature anomaly stands out, Andrew writes. Following the hottest June through August on record, and the globe's hottest ever month in July, last month's preliminary data has astonished climate researchers who long predicted such extremes eventually..... "We've never seen a record smashed by anything close to this margin," climate scientist Zeke Hausfather told Axios. "It's frankly a bit scary." "This month was, in my professional opinion as a climate scientist — absolutely gobsmackingly bananas," Hausfather posted on X.com. ... The extreme heat this summer and fall is the result of a combination of factors, starting with long-term, human-caused climate change. In addition, an increasingly intense El Niño event is underway in the tropical Pacific Ocean, which is drawing more heat out of the deep oceans.

"While a fraction of a degree might not initially strike us as significant," Texas A&M climate professor Andrew Dessler told Axios via email, "Even small increments in global temperatures have far-reaching consequences."
