Warm tropical winds from the western US are set to intensify this week, as climate change and “heat” combine to bring warmer temperatures to the region.
In the coming days, hot waves will sweep across the Pacific Northwest, as foretold Seattle and Vancouver reaches above 41C and 39C, respectively.
Seattle weather analyst Cliff Mass described the allegations as “extremely” and “crazy” in an area known for cold and rainy weather.
“To be honest, I’m scared to predict the future,” he said. he wrote Mass, professor of space science at the University of Washington.
Climate experts have warned that the storm could be deadly in the north, where many homes lack air conditioning and people are not accustomed to extreme heat.
Heat hundreds notes was established in the southwestern US via Utah, Arizona, Colorado, New Mexico and California last week.
Climate scientists say this may be unusual, since the planet is still warming up because of global warming. The global record for June 53.2C was written earlier this month in Death Valley, California.
“There is no doubt that global warming has increased dramatically as a result of climate change,” said Friederike Otto, director of the Environmental Change Institute at Oxford University.
“The most important thing is to know how hot the heat is,” he added, citing older people especially those at risk.
Extreme temperatures, combined with a severe drought, have caused wildfires, according to Otto Areas in California and Oregon already preparing for summer. burning hotter than last year.
The high-altitude space above the western US, often referred to as the “hot dome”, maintains a warm wave.
“This is a season that can go on, it can last for days,” said Dim Coumou, a researcher at the Potsdam Institute for Climate Impact Research. “It brings air, extreme heat[s]. ”
While climate change has already warmed the earth by 1.2C since pre-industrial times, scientists like Coumou believe it has also changed the shape of the atmosphere.
His research shows that the gradual weakening of jet aircraft during the summer makes these high-speed machines more stable, resulting in higher temperatures. The jet river, a group of fast-moving winds in the atmosphere, has a profound effect on the northern climate.
“You usually have a machine that comes in a few days,” Coumou said. “The advantage of these houses is that they can last a long time. The heat can really increase and you can get these long-lasting waves.”
Other parts of the world have also experienced heat waves this month, including the Russian Arctic.
The area around Verkhoyansk, which is known as one of the coldest places in the world, wrote new point more than 40C on June 21, according to a satellite launch from Copernicus, the EU’s global monitoring program.
This surpasses the 38C record recorded near Verkhoyansk last year.
