Climate change is a possible cause of some tornadoes

According to IRNA on Tuesday, the website of the American Hill newspaper wrote: the increase of global temperature has prepared the ground for the occurrence of deadly tornadoes that recently hit several states in the United States and killed at least 47 people in Kentucky.

Experts say climate change cannot be directly blamed for storms and tornadoes, but climate change is a compound that can cause tornadoes.

“Climate change may play a role in the formation of materials and compounds that we believe were necessary for hurricanes and hurricanes,” said Walker Ashley, a professor and atmospheric scientist at the University of Northern Illinois.

The tornado struck Arkansas, Illinois, Kentucky, Mississippi, Missouri and Tennessee on Friday night, killing dozens.

Storms are an unusual occurrence in December, and their occurrence this month of the year has led some to blame climate change for the event. US President Joe Biden has called on relevant agencies such as the US Environmental Protection Agency to investigate the role of weather in hurricanes.

In an interview with Hill, experts said the link between climate change and tornadoes is not yet causal.

James Elsner, a professor at Illinois State University who studies the changing nature of hurricane and hurricane hazards, also said that blaming the weather for hurricanes was like saying that fog caused a car accident.

“There may be more accidents when the weather is foggy, but it cannot be blamed,” he said.
He added: “If we know climate change like fog, we can not really say that it caused an accident, but it helped the accident.” This condition is necessary but not sufficient. Experts say the factors that cause tornadoes include warm, humid air at low levels, cool dry air at higher levels, and changes in wind speed and direction, called wind shear.

Harold Brooks, of the National Oceanic and Atmospheric Administration’s National Laboratory for Severe Storms, also said that climate change depends on hot and humid weather, but that its effect on wind formation is not clear.
According to experts, the tornado was unprecedented in the United States, and the media reported that at least 50 tornadoes occurred in different states, some of which covered a distance of about 200 miles, or more than 300 kilometers, and destroyed everything in its path. Removed.

According to CNN, eight states in the south and mid-west of the United States witnessed a tornado that caused power outages and tore off the roofs of buildings, overturned cars and heavy vehicles.
