Daily Heat Records Set On Tuesday Alone For At Least 50 Cities Just In The Eastern US As Heatwave Clamped Down

Nearly 130 million people were under extreme heat warnings or heat advisories on Thursday, according to NOAA’s Weather Prediction Center, with 282 locations breaking daily heat records this week, with another 121 equalling with previous highs, Noaa data showed. Daily heat records were set in at least 50 cities in the eastern US on Tuesday alone, according to the National Weather Service, with New York City recording its hottest day since 2012, according to NOAA.

Climate scientists blamed a rapidly warming Arctic for the heat dome – a consequence that they say is the result of the “stuck” weather patterns that come from a wavier polar jet stream, which can cause not just heatwaves but also heavy rainfall and floods.

A new study, published in the scientific journal Proceedings of the National Academy of Sciences, said found that stalled atmospheric patterns have tripled over the last 70 years. The authors of the study claim that while climate models predict that these patterns would occur more frequently with climate change, their study is the first to demonstrate that it is already happening – and will likely intensify as the planet continues to warm.

Climate Central’s climate shift index estimates that high temperatures over the past few days were at least five times more likely to occur because of human-caused climate change. Climate Central scientist Zachary Labe told Politico that the early heatwave “is a stark reminder that climate change is making these dangerous and oppressive heat waves far more likely, affecting millions of people”.
