Why so many people in the US either deny, or don't care about climate change:

for the vast majority of the public, the only known solution to preventing climate change is to vote Democrat. That's it. When your force-fed this narrative about a problem that really can't be seen or felt in many parts of the country, and then told by the same people "just vote for us and we'll fix the problem you can't see!" Many people will become suspicious or angry towards the issue and the people pushing it.

Yeah I remember Al Gore saying back in 2003 that by 2014 the polar ice caps would be almost completely melted.
