Milder winters have caused millions of Americans to stop stressing climate change, researchers from New York University and Duke University found in a recent study. For most people living in the United States, the average July temperature has risen only half a degree over the past 40 years, while the average January temperature has risen more than four degrees. Many Americans have reportedly taken these warmer winters as a reason to be less worried about global climate change, with many describing the change as “pleasant.” Patrick Egan, a researcher from New York University, said evidence suggests public opinion starts to change when summer temperatures start to rise, which scientists predict will happen within several decades.
