Urban Heat Islands: A Growing Threat to Millions in the U.S.

A recent analysis by Climate Central reveals that over 40 million people in the United States live in urban heat islands, where temperatures are elevated by at least 8 degrees Fahrenheit due to the replacement of natural land cover with buildings and pavement. The study highlights how certain populations are disproportionately affected by global warming, with cities like New York, Houston, and Los Angeles housing over a million people impacted by the urban heat island effect. Experts warn that higher temperatures in urban areas pose health risks, particularly for vulnerable communities, and suggest solutions such as increasing green spaces, using reflective materials, and planting trees to mitigate the impact of urban heat islands.
