all is now explained!

In her book This Changes Everything, Naomi Klein points to a study by sociologists Aaron McCright and Riley Dunlap that finds that white males are six times as likely to believe climate change “will never happen” as the rest of the adults surveyed.

They attribute this finding to the fact that white males are disproportionately threatened by the potentially disruptive effects that climate change policy will have on the kind of power they wield in society.

So in order to maintain their social rank, people who have more to lose are more likely to deny information that would force them to change their worldview.
