Record-Smashing Heat Grips US: Expansive Heatwave Breaks March Records in 14 States

• A gigantic heat dome has shattered March heat records in 14 US states and the nation as a whole, potentially becoming one of America's most expansive heatwaves.
• The heat dome is expected to persist until mid-next week, with meteorologists noting that 'basically the entire US is going to be hot' and the area of record temperatures is 'extremely large'.
• This heatwave's physical area likely surpasses historic events like the 2012 Upper Midwest/Northeast and 2021 Pacific Northwest heatwaves, though not as intense as Dust Bowl events.
• Four locations in Arizona and California hit 44.4 degrees Celsius, breaking the continental US record for hottest March day by 2 degrees Celsius.
• International climate scientists attribute the record heat to climate change, stating it was 'virtually impossible' without it and 800 times more likely due to fossil fuel burning.
