Americans are now nearly four times more likely to say they’re alarmed about the climate crisis than to be dismissive of it.

That’s the highest ratio ever since the Yale Program on Climate Change Communication (YPCCC) first began gathering data on American attitudes about climate change back in 2008. According to survey data collected in April and released last Friday, more than a quarter of the U.S. adult population — 26 percent — now thinks global warming and its attendant consequences are alarming. That’s more than double the 11 percent who were alarmed back in 2015, and almost four times the 7 percent who currently say the climate isn’t changing.

The data comes from a YPCCC project called Global Warming’s Six Americas, which categorizes Americans into six groups based on what they think about climate change. Using data from a YPCCC survey called Climate Change in the American Mind, the researchers identify where respondents stand on a continuum of climate worry. People fall into the “alarmed” category if their survey responses show that they’re very worried about climate change — these people are fully convinced of global warming’s reality and of the need for far-reaching political and individual action to address it. Those who land in the “concerned” think climate change is bad news but are less likely to prioritize action, and those in the “cautious” category recognize that the Earth is warming but aren’t convinced of its causes or of the need to take any action.
