Hi Pieter,
You've gotta remember that most people just chug along and don't pay much attention to the attempts of politicians posing as scientists to panic them about the termination of the human race. This kind of disguised political agitation has been going on as long as I've been around and I've been around a long time (relatively). It was particularly active during FDR's reign in the U.S. It subsided for a fair term, but it's been with us again, big time, for a couple decades.
Now Alan will tell you that he IS a scientist -- whatever that means -- and I don't doubt it. But is it possible that Alan could have a political view that might at least aim his scientific ideas in a particular direction? Perish the thought?
If global warming really is a threat, and looking at the history of long-term warming and cooling cycles I have to doubt it, then nothing's going to be done until a problem is visible, or felt, by a majority. And agitation in the (fake?) news media and on the internet isn't going to make this problem, if it is a problem, felt.
So the "scientists" crying wolf are spinning their wheels (to mix a couple metaphors). It's gonna take a disaster, or near disaster for them to get traction. But even on the basis of our current "scientific" guesses disaster is a long way off in the future.
Which is why this thread is a giant waste of time. But so is solitaire, and this is a lot more entertaining than solitaire.
