Latest World News: Heat waves in Europe, China and America could not have happened

The fingerprints of climate change are all over the intense heat waves hitting the globe this month, according to a new study. Researchers say the killer heat waves in the American Southwest and southern Europe could not have happened without the continued buildup of warming gases in the air.

These unusually strong heat waves are becoming more common, according to Tuesday’s study. The same research found that increases in heat-trapping gases, largely due to the burning of coal, oil and natural gas, have made another China heat wave 50 times more likely with the potential to occur roughly every five years.

A stagnant atmosphere, warmed by carbon dioxide and other gases, also made Europe’s heat wave 4.5 degrees Fahrenheit (2.5 degrees Celsius) hotter, those in the United States and Mexico 3.6 degrees Fahrenheit (2 degrees Celsius) and China’s 1.8 degrees Fahrenheit (1 degree Celsius). study find.

Several climatologists, using tree rings and other proxies for temperature records, say this month’s heat is likely the hottest Earth has been in about 120,000 years, easily the hottest in human civilization.

If there had been no climate change, such an event would almost never have happened, said the study’s lead author, Mariam Zachariah, a climatologist at Imperial College London. She called heat waves in Europe and North America virtually impossible without the increase in heat from the mid-1800s. Statistically, the one in China could have happened without global warming.

Since the advent of industrial-scale combustion, the world has warmed by 2.2 degrees Fahrenheit (1.2 degrees Celsius), so they are not uncommon in today’s climate and the role of climate change is absolutely overwhelming, said Imperial College climatologist Friederike Otto, who leads the World Weather Attribution team of international volunteer scientists carrying out the studies.

The particularly intense heat waves currently experiencing Texas, California, Arizona, New Mexico, Nevada, Baja California, Sonora, Chihuahua and Coahuila are likely to occur about once every 15 years in the current climate, according to the study.

But the climate is not stabilized, even at this level. If it warms a few tenths of a degree more, this month’s heat will become even more common, Otto said. Phoenix had a record 25 straight days of temperatures at or above 110 degrees Fahrenheit (43.3 degrees Celsius) and more than a week where the nighttime temperature never dropped below 90 degrees Fahrenheit (32.2 degrees Celsius)

The heat in Spain, Italy, Greece and some Balkan states is likely to recur every decade in the current climate, according to the study.

Because weather attribution researchers began their analysis of three simultaneous heat waves on July 17, the results are not yet peer-reviewed, which is the gold standard of science. But he used scientifically valid techniques, the team’s research is regularly published, and several outside experts told The Associated Press that it made sense.

The way scientists perform these rapid analyzes is to compare observations of current weather in the three regions to repeated computer simulations of a world that could have been without climate change, said study co-author Izidine Pinto, a climatologist at the Royal Netherlands Meteorological Institute.

In Europe and North America, the study does not claim that human-caused climate change is the sole cause of heat waves, but it is a necessary ingredient because natural causes and chance alone could not produce this.

Texas state climatologist John Nielsen-Gammon said the study was reasonable, but covers a large area of ​​the southwestern United States, so it may not apply to all places in the region.

In the United States, it’s clear that the entire southern tier is going to see the worst of the ever-worsening heat and this summer should be seen as a serious wake-up call, said University of Michigan environmental dean Jonathan Overpeck.

With heat waves, the most important thing is that they kill people and they kill, injure and destroy especially the lives and livelihoods of the most vulnerable people, Otto said.
