Alarmed about climate change?
A doom response might be as unhelpful as a denier/delayer/diverter attitude, if the conclusion is inaction.
Instead, we should act together to replace our energy dependence on fossil fuels with renewables.

Belief change predicts behavioral change for nonpolitical issues. For political ones, belief change predicts behavioral change only for Democrats evaluating Democratic (not Republican) issues. Republicans' belief change doesn't track with behavioral change on any political issue.
