— 17.23° Celsius — was recorded on July 6 . “It’s pretty clear that July is going to hit the record,” Pershing said.
He and his colleagues used computers to simulate the world with contemporary climate warming — 1.27 degrees C above preindustrial levels — and without it to isolate the influence of climate change on temperatures worldwide.Climate change is making hotter temperatures more likely to occur around the world, especially in the tropics. This map shows how many times more likely average temperatures for the month of July were due to climate change than without it.Last month more than 6.
The recent return of El Niño, a natural climate phenomenon that temporarily raises global average temperatures, is also “definitely having an effect,” said Pershing. But humans are warming the climate so fast that this year’s elevated temperatures could soon return even without El Niño. “This is the hottest El Niño year we’ve ever had,” Pershing said, “and five years from now, this will be a normal year.”
