Recent data analysis reveals a concerning trend of increasing heatwaves in cities across the United States, with human-caused climate change exacerbating the situation. The phenomenon known as the urban heat island effect is causing urban areas to experience temperatures up to 20 degrees Fahrenheit higher than surrounding green spaces.
All of the 50 most-populated cities in the US have witnessed a rise in temperatures over the past 50 years, with a significant increase in the number of 'extremely hot' days above 95 degrees. This summer, cities like Las Vegas and Phoenix have endured over 80 days above 95 degrees, while coastal cities such as Los Angeles and San Francisco have been relatively spared.
