REDDING (CBS News/AP) – Heat waves are setting all-time temperature records across the globe — again. Europe suffered its deadliest fire in more than a century. One of nearly 90 large fires in the Western U.S. burned hundreds of homes and forced the evacuation of at least 37,000 people near Redding, Calif. Flood-inducing downpours have pounded the Eastern U.S. this week. It’s all part of summer — but it’s all being made worse by human-caused climate change, scientists say. “Weirdness abounds,” said Rutgers University climate scientist Jennifer Francis.

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 record-setting hot events over more than 80 percent 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 build-up 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 said that allows the heat to stay in place over three areas where the kinks are: Europe, Japan and the western United States. The same jet stream pattern caused the 2003 European heat wave, the 2010 Russian heat wave and fires, the 2011 Texas and Oklahoma drought and the 2016 Canadian wildfires, Pennsylvania State University climate scientist Michael Mann said, pointing to past studies by him and others. He said in an email that these extremes are “becoming more common because of human-caused climate change and in particular, the amplified warming in the Arctic.” Climate scientists have long said they can’t directly link single weather events, like a heat wave, to human-caused climate change without extensive study. In the past decade they have used observations, statistics and computer simulations to calculate if global warming increases the chances of the events. A study by European scientists Friday found that the ongoing European heat wave is twice as likely because of human-caused global warming, though those conclusions have not yet been confirmed by outside scientists. The World Weather Attribution team said they compared three-day heat measurements and forecasts for the Netherlands, Denmark and Ireland with historical records going back to the early 1900s. “The world is becoming warmer and so heat waves like this are becoming more common,” said Friederike Otto, a member of the team and deputy director of the Environmental Change Institute at the University of Oxford. Erich Fischer, an expert on weather extremes at the Swiss Federal Institute of Technology in Zurich who wasn’t part of the analysis said the authors used well-established methods to make their conclusions. Georgia Tech climate scientist Kim Cobb said the link between climate change and fires isn’t as strong as it is with heat waves, but it is becoming clearer. In the United States on Friday, there were 89 active large fires consuming nearly 900,000 acres, according to the National Interagency Fire Center. The Carr Fire in Northern California has burned hundreds of homes and is threatening thousands of other structures. The blaze began Monday as a small wildfire and erupted into a living hellscape, CBS News’ Carter Evans reported from the city of Redding. “It’s like a war zone,” one woman said. “It’s just like a bomb just hit each house and just exploded.” So far this year, fires have burned 4.15 million acres, which is nearly 14 percent higher than average over the past 10 years. In Greece, a devastating fire this month — with at least 83 fatalities — is the deadliest fire in Europe since 1900, according to the International Disaster Database run by the Centre for the Research on the Epidemiology of Disasters in Brussels, Belgium. CBS News correspondent Seth Doane met 74-year-old Maria Nikolaou as she tried to start cleaning up on Wednesday in Greece. The fast-moving wildfire tore through her neighborhood. Her car was gutted, and in minutes her whole neighborhood was consumed. “Trees were falling everywhere, I was so scared,” she said. The first major science study to connect greenhouse gases to stronger and longer heat waves was in 2004. It was titled “More intense, more frequent and longer lasting heat waves in the 21st century.” Study author Gerald Meehl of the National Center for Atmospheric Research said Friday that now it “reads like a prediction of what has been happening and will continue to happen as long as average temperatures continue to rise with ever-increasing emissions of greenhouse gases from burning fossil fuels. It’s no mystery.” © 2018 CBS Interactive Inc. All Rights Reserved. This material may not be published, broadcast, rewritten, or redistributed. The Associated Press contributed to this report.
