Extreme heat intensifies across south-west US

4 min read

A heat dome over the US south-west has translated into extreme heat warnings from coast to coast, which continue to affect more than 110 million people.

Up to 38 cities might see temperature records smashed.

The extreme heat wave in Las Vegas poses a threat to surpass or tie the city’s all-time high temperature of 117F (47.2C) on Sunday.

It happens at a time when southern Europe is also experiencing record-high temperatures and Canada is coping with its worst wildfire season ever.

Scientists have long warned that the frequency and intensity of extreme weather events will rise as a result of climate change brought on by human activity.

On the outskirts of Los Angeles, hundreds of firemen from other parts of the south-western US have been battling brush fires in the sweltering heat and low humidity.

The National Weather Service (NWS) reports that on Sunday, the temperature in Death Valley, California, reached 128F (53.9C). It was there that 134F (56.7C), the highest temperature ever accurately measured on Earth, occurred.

Security personnel are on duty at premium casinos and hotels’ fountains to deter guests from leaping in, and Las Vegas’ often bustling streets are noticeably less congested than usual.

With no sign of relief in sight, El Paso, Texas, has been experiencing temperatures of at least 100.4F (38C) for more than a month.

For 17 days straight, Phoenix, Arizona, has experienced temperatures exceeding 109.4F (43C). On Sunday, the city was given a slight break from recent peaks thanks to thick cloud cover, although daytime highs of 114F (45.5C) were nevertheless recorded.

However, the heat is expected to last for some time, and authorities are cautioning that those who are more susceptible, such as young children, pregnant women, and the elderly, face a high danger of contracting a heat-related illness.

homeless individuals with third-degree burns are reportedly being treated by mobile clinics. In some areas of California and Nevada, public buildings have been transformed into “cooling centres” where people can escape the heat.

Park ranger Matthew Lamar noted the severe heat in Death Valley, saying, “We hadn’t hit 130F (54.4C) here in over 100 years. After that, we received 130 in 2020 and 2021, and we may do it once more this weekend.

Tourists who wanted to “experience the extremes” were drawn to the area because of the weather, he continued.

However, several tourists argued that people shouldn’t forget that these extremes are a sign of climate change.

“People are coming out here to celebrate this,” Tom Comitta said in an interview with Reuters on Saturday. Everyone is thrilled. It is not a turning point. It’s called Happy Death Day by me.

When air is forced downward by a zone of high pressure, it is compressed and heated, creating a heat dome. The cycle of air sinking through the ‘dome’s’ centre and rising along its sides is created when the warmer air rises once again.

The pressure also limits the formation of other weather systems, such rain clouds, that would chill the region.

According to the NWS, the present system affecting the southwest of the US is “one of the strongest” of its sort to have ever affected the area.

According to The Weather Channel, the dome will spread across the nation’s south by the middle of next week, which means temperatures in other southern US states will soar.

Other regions of the US are preparing for severe thunderstorms and flash floods, and the ongoing wildfires in Canada could cause another round of bad air quality in the northeastern states.

At a press conference, New York Governor Kathy Hochul stated, “As if the rain coming out of the sky isn’t enough, if you start looking up tomorrow, you’re going to see a similar situation in what we had a couple of weeks ago because of the air quality degradation [from the wildfires].” And as I already stated, this might be the new normal for us.

Since the start of the industrial age, the world has already warmed by around 1.1C, and temperatures will continue to rise unless governments drastically reduce emissions.
