Southern Europe is bracing for a second heat storm in a week, with Italy, Greece and Spain, along with Morocco and other Mediterranean countries, being told temperature records could be broken on Tuesday. A new anticyclone that pushed into the region from north Africa on Sunday could lift temperatures above the record 48.8C (120F) seen in Sicily in August 2021, and follows last week’s Cerberus heatwave. The European Space Agency said the next week could bring the hottest temperatures ever recorded in Europe in a heatwave named Charon after the Greek mythological boatman who ferries souls to the underworld. …A study recently published in Nature Medicine said more than 60,000 people died because of last year’s summer heatwaves across Europe, with the highest mortality rates seen in Italy, Greece, Spain and Portugal. …Unrelenting temperatures are also being felt in the US, where sweltering conditions put more than one-third of Americans under extreme heat alerts.
