Behind ongoing heatwave in the US, a combination of heat dome and climate change
The United States is experiencing a prolonged heatwave, driven by a persistent 'heat dome' that is expected to raise temperatures by 10-20 degrees Fahrenheit above average over the Fourth of July weekend. The National Oceanic and Atmospheric Administration (NOAA) anticipates that numerous daily temperature records will be broken, reflecting a broader trend of increasing summer heatwaves, which have roughly doubled in frequency since 1980. This phenomenon is exacerbated by man-made climate change and intensified natural events like El Niño, impacting over 100 million people in the region.
