You are right. Specifically, the question was: > ENV17: Within the next 10-15 years, how likely is that the earth will become uninhabitable and humanity will be wiped out? The other questions were directly about climate change, so presumably that framing had an effect. But on that short a time span, I think nuclear warefare has a more likely (though distant) chance of wiping out humanity than climate change (and I'm no climate change denier), and I could imagine some of the respondents reasoning similarly.
