Europe heatwave: Nearly all major Italian cities on red heat alert

A heatwave in Europe has led to red alerts for extreme heat in most of Italy’s major cities. The high temperatures, expected to peak on Wednesday, have put 23 cities on high alert.

The heatwave is affecting millions of people in the northern hemisphere and is accompanied by wildfires in Greece and the Swiss Alps. The heatwave is caused by a high-pressure system bringing warmer air from the tropics, while a jet stream remains stuck over central Europe.

The extreme heat is forecasted to continue through Wednesday in southern Europe, with temperatures exceeding 40°C (104°F). Italy’s health ministry has activated “heat codes” in emergency rooms to handle the increase in heat-related illnesses.

There has been a 20% rise in patients admitted with symptoms such as dehydration, exhaustion, and heat stroke. Record-breaking temperatures of 41.8°C (107.2°F) were recorded in Rome. Red alerts are also in place in Spain, Greece, and parts of the Balkans. The heatwave is expected to continue into August, according to the World Meteorological Organization.

Other parts of the world, including the US and China, are also experiencing extreme heatwaves. Climate change is cited as a significant factor in the increasing frequency and intensity of heatwaves.
