North → East expansion… “Near 40 degrees Celsius next week”
Doubt about climate change… Academia “No natural occurrence of record heat waves”
(Seoul = Yonhap News) Reporter Yuhan-ju = There is a forecast that tens of millions of people will groan in the sweltering heat due to the rise of huge heat domes in the United States.
CNN reported on the 18th (local time), citing a forecast from the meteorological agency, that the heatwave that recently hit the United States will get worse next week.
Already last week, the United States suffered from an untimely heat wave.
The U.S. Meteorological Administration issued a heat wave advisory on the southeastern coast of Mexico, the Great Lakes, and eastern Carolina on the 13th and advised 17.5 million residents to refrain from going out and stay indoors if possible.
On the 15th, a third of the U.S. population was advised to stay at home to avoid the heat.
According to reports, more than 25 million people in dozens of U.S. states were under heat wave warnings that day.
In particular, temperatures from Lincoln, Nebraska to Fargo, North Dakota are expected to exceed 37 degrees Celsius this weekend.
The problem is that the heat will continue into next week due to the hot sea bream.
Heat dome refers to a phenomenon in which high pressure stagnates in an area and hot air is trapped, leading to cauldron heat.
The sea bream, which currently resides on the northern plains of the United States, will move eastward and bring a record-breaking heatwave next week, CNN reported.
In the case of St. Louis, Missouri, which recorded a high of 30 degrees on that day, the highest temperature on the 21st could soar to 37.7 degrees.
Chicago, where the highest temperature did not exceed 21 degrees on that day, is expected to soar to a high of 35 degrees on the 20th.
Raleigh, North Carolina is expected to reach a high of 37.8 degrees Celsius on the 22nd.
The heat dome phenomenon, which brings such unusual heat, is observed not only in the United States but also in other parts of the world.
In particular, the frequency and intensity of sea bream tend to increase and persist for a long time, and scientists suspect climate change as the cause.
As global warming worsens due to the increase in the use of fossil fuels, the number of heat seams also tends to worsen.
Some scientists suspect that changes in the jet stream due to warming may be related to the heat dome.
Although the specific cause is not clearly established, it is a general consensus in the academic world that record heatwaves do not occur naturally.
“Climate change is a game changer for heatwaves,” said Friederike Otto, a climate expert at Imperial College London, UK.
He analyzed that the frequency of heat waves in Europe alone has increased by more than 100 times because of human actions that dump greenhouse gases into the atmosphere.
“Scientists have shown that human-induced climate change is making certain heatwaves more intense,” said Vicky Thompson, a climate scientist at the University of Bristol.
