Discouraging. Although scientists overwhelmingly agree about human-caused warming, I would have hoped that scientists would be more immune to confirmation biases than this. I guess scientists are fully-flawed humans after all.
These results tell us more about human nature than about climate change. There is considerable literature about how facts may or may not influence beliefs and attitudes, and how these may or may not in turn lead to actual behaviours. So if we are still working on beliefs and attitudes among the best-informed people in the world, it is going to be a long journey before everyone changes their climate-related behaviour.
