Clearly there is a problem here that requires adaptation to the inevitable effects over the next two to three decades. As John and my other colleague have said, there's nothing we can do about this. This is inertia that's built into the system. The differences, however, beyond two to three decades are huge, depending upon the greenhouse gas path we choose to travel.
But there are steps we have to take as well to try to protect ourselves in the short term against the impact we'll undoubtedly feel during these first few decades.
So I agree with you; it's a two-stage process that we have to follow.
