Human-derived climate change dramatically upped the odds of record-shattering heat, a new study concludes. London broiled at record temperatures last month, it was a rare occurance easily labeled “extreme weather.” But the heat surge that rippled airport runways and led to major health alarms can’t be considered entirely random bad luck.

Scientists say record temperatures are 10 times more likely to have happened in modern times versus the pre-industrial era. When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. London’s heat wave, which peaked on July 18 and 19, set a record for the hottest temperature in the history of the U.K., at 104.54°F.

On July 19, a total of 34 weather stations broke the previous all-time national temperature record. The scorching readings hit as parts of western Europe sweltered under their own streak of extreme highs. Two years ago, the Met Office posted an alarming, red-splashed temperature map.

U.K. weather officials drew a scary heatwave map for 2050 — this week it came true, 28 years early. July 2022’s record and the real map shown across television and social media was nearly identical to the 2050 hypothetical. Heat extremes and precipitation extremes are far more likely and intense now.

Extreme heat events in 2021 in the typically temperate U.S. Pacific Northwest have been found to be virtually impossible to occur without human-caused warming. "In Europe and other parts of the world we are seeing more and more record-breaking heatwaves causing extreme temperatures that have become hotter faster than in most"
