The United States was hit hard by a series of catastrophes associated with climate change on Tuesday – floods, devastating fires, storms and potentially dangerous heat waves for a third of the country’s population – with the arrival of summer, France-Presse reported, quoted by Agerpres .
Nearly 120 million Americans have been affected in one degree or another by a heatwave alert, a phenomenon that has hit parts of the Midwest and the southeast.
“A high pressure dome should produce higher than normal temperatures, or even record temperatures, throughout the area, today and tomorrow (Wednesday).”warned the specialists from the US National Meteorological Service.
“This heat, accompanied by a high rate of humidity, is likely to generate temperatures well above 37 degrees Celsius in many areas.”they warned.
In some parts of Indiana, Kentucky and Ohio, mercury will reach thermometers of up to 43 degrees Celsius. This high-pressure area triggers exceptional phenomena at its periphery, said Alex Lamers, an expert with the US National Bureau of Meteorology.
“In many cases, if a strong heat wave occurs, you will immediately find storms and tornadoes, sudden floods, and torrential rains near its edges.”explained the American specialist.
At the northern edge of this heat dome, high temperatures collided with cold air masses and created violent storms on Monday, leaving hundreds of thousands of people without electricity in the Midwest.
That cold front risks causing other devastating weather, such as hail and strong winds.
In the western part of the country, images released by the National Parks Agency testify to the devastation caused by the floods in the famous Yellowstone National Park.
All entrances to this vast, nearly 9,000 km2 natural park, located between the states of Wyoming, Montana and Idaho, will remain closed until further notice due to “extremely dangerous conditions” caused by a flood and torrential rains. All visitors who were still in the park were asked to leave on Tuesday.
“Levels measured on the Yellowstone River are beyond record levels”stated the National Parks Agency on its website.
Floods caused landslides and landslides, destroying multiple sections of roads “and more bridges could be affected”added the same US agency.
Heatwave alerts have been issued in parallel in several regions of California and Arizona, where high temperatures and chronic drought are further exacerbating fire hazards.
Two outbreaks, each of which have already destroyed more than 120,000 acres, continued to burn in New Mexico on Tuesday.
Firefighters have been trying for weeks to isolate the flames at Black Fire and Hermits Peak, which are fueled by exceptionally dry vegetation.
New Mexico and almost the entire southwestern United States are facing a historic drought, and dozens of fires have already broken out in the region before just before the start of summer.
Firefighters find that the frequency, size and intensity of forest and vegetation fires have steadily increased in recent years.
Fires are common in the western United States, but they have become more intense due to global warming caused by human activities, especially fossil fuels.
According to Alex Lamers, although it is difficult to make a direct link between global warming and an isolated meteorological phenomenon, climate change is undoubtedly an aggravating factor.
