Climate change. The greatest hoax ever perpetrated on mankind. The vast majority of people who eat this slop up couldn’t even identify the difference of a cumulonimbus(spelled right?)and a lenticular cloud. Or know what universal solvent is. And so on.
Gullibility is also a factor. Chicken Little claiming the sky is falling, or the story of The Boy Who Cried Wolf, is lost on them. They don’t see they are being manipulated.
The bottom line is that they WANT to believe because it buys them membership in “the good side”, which really is nothing but deception that will cause human suffering, which is actually evil.
