...until then, don’t try to sell it as an immutable truth. “The debate about global warming is over,” crowd is selling faith, not fact...they have completely lost sight of the scientific method. They have a conclusion and steps that need to be taken immediately to abate the problem...yet they still seek evidence for it, by any means necessary.
This is the way it has always been done. If you believe you have the science to back up your conclusions you have the immutable truth. Then when you are proven wrong, you get egg all over your face. This is science at is highest level with politics, religion and economics thrown in.
