......and in regards to that link.........
I will not repeat what I have already stated in this thread on this issue, but to,........ quote:
"I wonder whether the green nutcases will also start to threaten the skeptical world with nuclear weapons. You may choose: 0.5 °C of man-made warming (or cooling) in the 21st century, or a global nuclear Armageddon? Which of these two "catastrophes" is worse? ;-) The laws of Nature imply that we will only get the first one (i.e. nothing happens) if we manage to stop the fanatics but the historical experience suggests that we may get both if we will fail to do so."
.....................is way OTT! Why bring nuclear war into the equation? For dramatic effect I suppose, but it is so way off! Nuclear war over environmental issues? Over oil, water, political ideology, Afghanistan, maybe, but who would bring nuclear conflict into this issue but someone running out of sound argument. As for the "historical" reference, when was nuclear weapons used to make a state, and the world stop and think beyond Hiroshima and Nagasaki??
Obama is the last US President to use nuclear weapons over environmental and trade issues. He, and all his advisors know the outcome such a move would produce, with the world shuddering at the very thought!
No, reference to nuclear war is purely shock tactics by one side against the other and is totally irresponsible.

Lizzie, I should point out that Lubos Motl has an acerbic sense of humour. I rather think it was a tongue-in-cheek comment, parodying recent comments by alarmists on the web that climate sceptics should be put on trial or executed - yes, really.
