Unprecedented Number of Heat Records Broken Around World This Year

An anonymous reader shares a report: A record 15 national heat records have been broken since the start of this year, an influential climate historian has told the Guardian, as weather extremes grow more frequent and climate breakdown intensifies. An additional 130 monthly national temperature records have also been broken, along with tens of thousands of local highs registered at monitoring stations from the Arctic to the South Pacific, according to Maximiliano Herrera, who keeps an archive of extreme events.

He said the unprecedented number of records in the first six months was astonishing. 'This amount of extreme heat events is beyond anything ever seen or even thought possible before,' he said. 'The months from February 2024 to July 2024 have been the most record-breaking for every statistic.' This is alarming because last year's extreme heat could be largely attributed to a combination of man-made global heating -- caused by burning gas, oil, coal and trees -- and a natural El Nino phenomenon, a warming of the tropical Pacific Ocean surface that is associated with higher temperatures in many parts of the world. The El Nino has been fading since February of this year, but this has brought little relief.

'Far from dwindling with the end of El Nino, records are falling at even much faster pace now compared to late 2023,' said Herrera. New ground is broken every day at a local level. On some days, thousands of monitoring stations set new records of monthly maximums or minimums. The latter is particularly punishing as high night-time temperatures mean people and ecosystems have no time to recover from the relentless heat. In late July, for example, China's Yueyang region sweltered though an unprecedentedly elevated low of 32C during its dark hours, with dangerously high humidity.
