Watts up with dismissing the scientific consensus?

I keep hearing people put down the notion of trusting the "consensus view". And they do it with such self-certain distain, they imply it's so cheap to simply accept expert opinion, like some sort of intellectual cop out. Anyone out there willing to give a shot at explaining why we should trust experts? Heck any one (JS?) want to explain why they think they shouldn't trust experts and their collective learned opinion? and how about that consensus . . .
Scientific organizations endorsing the consensus The following scientific organizations endorse the consensus position that "most of the global warming in recent decades can be attributed to human activities": American Association for the Advancement of Science American Astronomical Society ........ Royal Society of New Zealand Polish Academy of Sciences https://www.skepticalscience.com/global-warming-scientific-consensus-intermediate.htm
Where is your science? On websites named “skepticalscience"? Sounds like a real winner. I don’t see the point here. You got 97% of the scientists saying that consensus is that man is having an effect on the climate. What more do you need? Are you trying for 98% or 100%? Hell, there are people who still believe man has not been to the moon yet. You are never going to get 100% of anything concerning the human factor. The point you are trying to make was made and accepted years ago. All I see happening most of the time is that some congressman who has access to congressional reports that are unavailable to the public. These reports are costing the taxpayers a lot of money. The congressman tries to make points from these reports that the general public is mostly unaware of and creates a communication problem. Gets labeled a denier and the thought the congressman was trying to make never gets fully understood. The real facts are that the science of how much man-made warming is taking place is not solid. Until a baseline of the nature’s heat of the earth is available there is no legally accepted baseline. And if we are going to be a nation of laws, then we need this information. The computer models are working on this problem right now. As far as the experts, every court case has experts on both sides of the case. I guess you have to pick the experts you believe the most. Myself, I am backing and supporting the IPCC. Always have, and so far I like the path they are taking.
