Nearly 4 in 10 Americans think there's a good chance climate change will cause human extinction, according to a new poll released Wednesday.
The survey from the Yale Program on Climate Change Communication found that 39 percent think the odds of global warming ending the human race are at least 50 percent.
Fifty-eight percent of respondents said climate change is human-caused — the highest number since the program began surveying on the topic in 2008.
About a quarter of respondents said providing a better life for younger generations is the most important reason to reduce global warning, with 16 percent of respondents saying that preventing the destruction of most life on Earth is the most important reason.
The survey was polled 1,266 adults between May 18 and June 6 and has a margin of error of 3 percentage points.
