Plenty of scientists (not earning a paycheck through any government) say it's bullshit as well. Let me explain something to you:
Our government (mostly Democrats) have been trying to get more and more control over the people as time went on. To some degree, they've been pretty successful. It's the one advantage about being older. You remember when the people in this country had much more liberty than today. But the two things stopping Democrats from total control of the people are healthcare and energy. If they could get total control over those two vestiges, they will indeed have total control over all of us.
In our system of government, our military cannot march into hospitals and energy producers and simply take over no matter how strong their leadership is. So how can they take over? Make the people beg them to take over these things.
This is done financially and through fear mongering. Make healthcare unaffordable and convince people that we are ending the world with our use of fossil fuels. Or as AOC once said, we only have ten years left before the end of the world. If they can convince enough people, they will beg the Democrats to save our existence.
So now you know (as the late Paul Harvey used to say) the rest of the story. This pollution, global warming, climate change started decades and decades ago, and in spite of the trillions we put into combating these things, the environmental kooks are more pissed off today than they were 50 years ago.
