Politics works in cycles and maybe we are seeing the backlash of a lot of people starting believing in climate issues. Now that actions start being taken, people not caring about climate start pushing back because they need to change their lifestyle, and some parties (right wing/populists) promise them nothing has to change.
I think though that is getting harder and harder to ignore actual climate issues (storms, floods, heat), wonder what will be these parties next claim to convince voters "is the left wing/immigrants that generated the floods?"...
