As much of the nation swelters under temperatures that have, sparked wildfires and taxed the infrastructure keeping people cool, experts warn that heat waves will only get more common.
Heat waves are just one of the types of extreme weather climate change becoming more frequent — but it's already led to deaths both in the U.S. and around the world this year.
“This is the climate change that we've been promised by scientists,” Michal Nachmany, founder of Climate Policy Radar, told CBS News foreign correspondent Ramy Inocencio about record-breaking temperatures in the U.K. this week.
“This level of extreme weather is life-threatening, and we really want to make sure that people are not under any illusion, that this is serious and this is here to stay for the foreseeable future,” Nachmany said.
In Phoenix, for example, heat kills as many people as homicides, David Hondula, the city's director of heat response and mitigation, told‘ Ben Tracy.
Climate scientist Daniel Swain, who writes about weather in the Western U.S. on his website, pointed out last week that what he called “a prolonged and locally intense heatwave across all of western North America in the coming weeks” is “the least extreme such event currently ongoing across multiple continents,” including Europe and China.
The Associated Press reports that heat waves in China earlier this month – specifically in the Zhejiang province, east of Shanghai – saw temperatures exceeding 42 degrees Celsius (up to 107 degrees Fahrenheit). The heat also hospitalized people in the Henang, Sichuan and Heilongiang provinces.
The human toll of heat this year is rising both around the world and closer to home. In North Texas, where 66-year-old woman died from heat-related causes this week – .in July compared with last year – and officials said a
“We have a pretty significant drought all across north and central Texas. This drought caused us to go into summer much earlier than we normally see,” Sarah Barnes, a meteorologist with the National Weather Service office in Fort Worth, Texas, told CBS News' Kris Van Cleave.
Those drought conditions prompt more hot temperatures, the NWS said.
“We're certainly seeing more extreme weather due to climate change,” Barnes added.
While air conditioning is, it isn't common everywhere. And when the power goes out, air conditioning goes out with it.
“There's been a doubling in the number of blackouts per year in the last five years, and the majority of the blackouts are happening in the summer, in warm weather,” Brian Stone, a professor at the Georgia Institute of Technology who studies urban climate change,earlier this year.
Inby extreme temperatures this summer — and officials in other states could be as well.
“Most summers these days are the hottest summer ever. What overlays that is just a creeping risk of antiquated infrastructure … and those trends are converging at the wrong time,” Stone said.
This week the,or about 104 Fahrenheit – 30 degrees hotter than typical summer temperatures in a country where less than 5% of homes were estimated to have air conditioning, CBS News foreign correspondent Roxana Saberi reports.
“Climate change has everything to do with the extreme weather that we're seeing at the moment, and it's human-induced climate change. It's not a natural variation,” Kirsty McCabe, a meteorologist at the U.K.'s Royal Meteorological Society, told CBS News correspondent Roxana Saberi.
The extreme heat has contributed to wildfires in the U.K. 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 our grandchildren.'” Nachmany said. “This isn't. This is us. This is here. This is now.”
