Climate models project dangerous combinations of heat and humidity by the end of the 21st century. New research says these extremes are already happening.

Most of the United States was warmer than average. Wet conditions in March eased drought concerns in Southern California, but extreme dryness around the Gulf Coast raised the chances of drought there.
