The US West Coast is bracing for extreme temperatures, with the thermometer in desert cities expected to reach up to 49 degrees Celsiuswhile Phoenix in Arizona completed 100 consecutive days during which the temperature has not dropped below 38 degrees Celsius.

In California the temperature is expected to reach 45 degrees Celsius in some parts of Los Angeles.

According to meteorologists, an anticyclone will cause temperatures to rise above normal levels, in some cases even 10 degrees above normal.

The wave heatwave It will begin at noon today and is expected to last until Friday night, the National Weather Service (NWS) said.

The upscale neighborhood of Woodland Hills, located about 15 kilometers from Malibu, is expected to record the hottest temperature in Los Angeles County.

Karen Bass, the city’s mayor, announced that many air-conditioned areas will be open to citizens who do not have access to air conditioning.

Coastal areas of Los Angeles, which have had a milder summer so far this year, will this time see temperatures on par with those far from the Pacific Ocean, according to climatologist Daniel Swain.

“Most areas near the coast were spared this summer’s record temperatures,” meaning that “although most of California had a record-breaking summer in terms of high temperatures, it did not affect the majority of residents.” as most live in the coastal areas, he explained.

In Death Valley, one of the hottest places on Earth, the thermometer will reach 47°C, just below the 50°C recorded in July.

The neighboring state of Arizona will also be affected by the heat. In the city of Phoenix yesterday — Tuesday — was the hundredth day in which the temperature did not fall below 38° Celsius.

The previous corresponding record dates back to 1993, when the temperature in Phoenix remained above 38°C for 76 days.

Recurring heat waves are a sign of climate change caused by people’s dependence on fossil fuels, scientists point out.

Recent research by the US Environmental Protection Agency (EPA), which analyzed data from 50 major US cities, concluded that the average frequency of heat waves doubled every year in the 1960s and quadrupled every year in the 2010s and 2020s.
