WASHINGTON: A widespread heat wave is expected to deliver a fresh batch of record temperatures along the US West Coast, as millions of Americans sweat through a heat dome that is also hovering over Arizona and Nevada.

About 36 million people — roughly 10% of the country — are under excessive heat warnings coming from the heat dome centered over California, the National Weather Service said on Sunday. Fossil fuel-driven climate change is driving extreme heat waves across the world and will continue to deliver dangerous weather for decades to come, research shows.

High temperatures are forecast to meet or exceed daily high records in Washington state, Oregon, California, northern Arizona and central Idaho.

In Death Valley National Park along the California-Nevada border, the NWS projects highs near 130 degrees Fahrenheit (54 degrees Celsius) through Friday. On Saturday, the thermometer reached 128 degrees Fahrenheit there, breaking a 17-year record, and reached 115 degrees Fahrenheit in Las Vegas, which tied a record that was set in 2007.

Temperatures are running as much as 20 degrees above normal this time of year in places like Redding, a city a northern California that hit an all-time high of 119 degrees Fahrenheit (48 degrees Celsius) on Saturday, NWS meteorologist Bryan Jackson said.
