Re: The universe will now disappear
"They are all wrong !"
Wrong. They are all approximations. Every scientific theory is an approximation; the question is how good (or bad) an approximation. Newtonian mechanics stood until Special Relativity came along, and Special Relativity stood until General Relativity came along. General Relativity and quantum theory are both very good approximations, but since they are inconsistent with each other, they are in fact both wrong in exactly the same way that the IPCC models are wrong - because all approximations are wrong, by your definition.
Climate models are hard - much harder than relativity and quantum mechanics, in a mathematical sense. So it's no surprise that they are less good approximations than physics.
As for the universe, yes, if it turns out that we're in a freaky area where matter predominates, then eventually we'll annihilate with another freaky area where antimatter predominates. So what? You'll never know about [bit stream suddenly ends]
