Heat waves are hitting all over the world. Scientists say climate change is making it more frequent

As a lot of the nation suffers under the temperatures that it has Canceled outdoor sportshas caused wildfires and taxed infrastructure to keep people calm, and experts warn heat waves will become more common.

Heat waves are just one of the types of climate change extremes that are becoming more frequent — but they have already led to deaths both in the United States and around the world this year.

“This is the climate change that scientists have promised us,” Michel Nachmani, founder of Climate Policy Radar, told CBS News foreign correspondent Rami Inocencio of record temperatures in the UK this week.

“This level of severe weather is life threatening, and we really want to make sure that people are not under any illusion, that this is dangerous and that is there to stay for the foreseeable future,” Nachmani said.

In Phoenix, for example, heat kills as many people as homicides, said David Hondola, the city’s director of heat response and mitigation, CBS NewsBen Tracy.

Climate scientist Daniel Swain, writing about weather in the western United States on his website, noted last week that what he called “a long, locally intense heat wave across western North America in the coming weeks” is “the least extreme of such events.” Currently across multiple continents,” including Europe and China.

The Associated Press reported that heatwaves in China earlier this month – specifically in Zhejiang province east of Shanghai – saw temperatures exceeding 42 degrees Celsius (up to 107 degrees Fahrenheit). Heat was also transferred to hospitals in Henang, Sichuan and Heilongyang provinces.

The human toll from heat this year is on the rise worldwide and closer to home. In North Texas, where Firefighters fought 780% more fires In July compared to last year – officials said a A 66-year-old woman died Heat-related reasons this week. La Niña helps drive drought and high temperatures.

“We have significant droughts across northern and central Texas. This drought has caused us to enter summer much earlier than we normally see,” Sarah Barnes, a meteorologist with the National Weather Service’s office in Fort Worth, Texas, told CBS News. Chris Van Cleef.

The NWS said these drought conditions are leading to more high temperatures.

“We are definitely seeing more extreme weather due to climate change,” Barnes added.

While air conditioning One of the best ways to stay calmIt is not common everywhere. And when the electricity goes out, the air conditioning goes out with it.

Brian Stone, a professor at the Georgia Institute of Technology who studies urban climate change, said: He told CBS Moneywatch earlier this year.

in Texas, the electrical grid has already been taxed Extreme temperatures this summer — and officials in other states Warning their energy infrastructure It could be.

“Most summers these days are the hottest ever,” Stone said. “What overlaps is just a creeping danger of antiquated infrastructure…and these trends are converging at the wrong time.”

this week The UK saw a record 40°Cor about 104 F — 30 degrees hotter than typical summer temperatures in a country where it’s estimated that less than 5% of homes have air conditioning, CBS News foreign correspondent Roxana Sabry reports.

Kirsty McCabe, a meteorologist for the UK’s Royal Meteorological Society, told CBS News: “Climate change has everything to do with the extreme weather we’re seeing right now, and it’s man-made climate change. It’s not natural change. “. Correspondence to Roxana Sabry.

Extreme temperatures have contributed to bushfires in the UK and across Europe – including in France, Spain, Italy, Greece and Portugal.

“We used to look at polar bears, and then we used to say: This is about our children and grandchildren,” Nachmani said. “This is not. This is us. This is here. This is now.”
