The earth has never warmed and cooled before.
Never had floods or volcanoes before either. These are all manmade horrible results of us existing here.

Understand that it’s not about facts. They know the science points to a cooling trend, but the opportunity to implement a social system with total population control is too ripe. As temperatures start to dip, it’ll become obvious that “warming” is a hoax, and they’ll declare that their system saved the day. All is well!
