Los Angeles, US | July 28 H eat waves are setting all-time temperature records across the globe, again. Europe suffered its deadliest fire in more than a century, and one of nearly 90 large fires in the U.S. West burned dozens of homes and forced the evacuation of at least 37,000 people near Redding, California. Flood-inducing downpours have pounded the U.S. East this week.

It’s all part of summer — but it’s all being made worse by humancaused climate change, scientists say.

“Weirdness abounds,” said Rutgers University climate scientist Jennifer Francis.

Japan hit 106 degrees on Monday, its hottest temperature ever. Records fell in parts of Massachusetts, Maine, Wyoming, Colorado, Oregon, New Mexico and Texas. And then there’s crazy heat in Europe, where normally chill Norway, Sweden and Finland all saw temperatures they have never seen before on any date, pushing past 90 degrees.

So far this month, at least 118 of these all-time heat records have been set or tied across the globe, according to the National Oceanic and Atmospheric Administration.

The explanations should sound as familiar as the crash of broken records.

“We now have very strong evidence that global warming has already put a thumb on the scales, upping the odds of extremes like severe heat and heavy rainfall,” Stanford University climate scientist Noah Diffenbaugh said.

“We find that global warming has increased the odds of recordsetting hot events over more than 80% of the planet, and has increased the odds of record-setting wet events at around half of the planet.”

Climate change is making the world warmer because of the buildup of heat-trapping gases from the burning of fossil fuels like coal and oil and other human activities.

And experts say the jet stream, which dictates weather in the Northern Hemisphere, is again behaving strangely.

“An unusually sharply kinked jet stream has been stuck in place for weeks now,” said Jeff Masters, director of the private Weather Underground. He says that allows the heat to stay in place over three areas where the kinks are: Europe, Japan and the western United States.
