How does one prove global warming is based on humans and isnt a natural phenomenon? Then claim that the proof is so substantial/wide spread that its obvious to everyone involved. They would _need_ to know of wrong doing to be guilty of turning a blind eye/disinformation to it, right?
FWIW, I do think we (humans) are the cause of the earth warming up and, those with the biggest part at play should be held accountable for their actions.
