Wide Impact of Climate Change Already Seen in U.S.,
Study Says The effects of human-induced climate change are being felt in every corner of the United States, scientists reported Tuesday, with water growing scarcer in dry regions, torrential rains increasing in wet regions, heat waves becoming more likely and more severe, wildfires growing worse, and forests dying under assault from heat-loving insects.
