A new poll asked U.S. adults about their experiences and found that 78 percent of those asked had recently experienced a severe weather event –tornado, hurricane or tropical storm, wildfire, major flooding, major drought, and severe cold/winter storms. More than half said that extreme heat was the most impactful weather in the last five years, and nearly a quarter of the survey respondents reported that climate change is threatening their health a great deal or a lot. The report is a joint project from the Robert Wood Johnson Foundation, National Public Radio, and the Harvard T.H. Chan School of Public Health.
