More Extreme Heat Waves
Global Warming's Wake Up Call
Global warming will bring more extreme heat waves. As the United States warms another 4 to 11°F on average over the next century, we will have more extremely hot summer days. Every part of the country will be affected. Urban areas will feel the heat more acutely because asphalt, concrete, and other structures absorb and reradiate heat, causing temperature to be as much as 10°F higher than nearby rural areas.
