Taken as a whole, scientists are fairly open to new evidence, but conservative about making non-orthodox claims about that evidence. Climate research is harder because it's a slow-moving phenomenon. 'People all over' are not in a position to understand that.

'People' also tend to be slow at recognizing how much different their lives are from those a century ago - because of science discoveries. Taking away all those advantages for a while would put a quick stop to most of their negativity. So what they think is not terribly significant.
