Global Warming - past the point of return

In this article linked by my header, scientists are claiming global warming is so entrenched it is now past the point of no return. GOOD. Now that we can't do anything about it, we can take this off the table and move on to more important issues. Once we make that claim, will scientists then say they may be wrong about the point of no return. Funny how they can be selectively sure of their correctness. If they are wrong about the point of no return, then they logically could be wrong about global warming itself. "No, no were sure about that part." Right, man.
