Actually they have.<quoted text>It is not the responsibility of ‘climate realist’ scientists to prove that dangerous human-caused climate change is not happening. Rather, it is those who propose that it is, and promote the allocation of massive investments to solve the supposed ‘problem’, who have the obligation to convincingly demonstrate that recent climate change is not of mostly natural origin and, if we do nothing, catastrophic change will ensue. To date, this they have utterly failed to do so.
There is no proof possible, on;y models & predictions based on events past & present.
Look at this hurricane. Many weather scientists had Sandy going out to sea.
But one group said no. Their model had it turning left.
If it were up to the moronic right, they would have demanded proof & called these people morons & have done nothing to prepare.
Thank Gos we had sane people in charge. Many lives were saved.
