Working Group I, remember, was supposed to tell us the scientific case for man-made global warming. If our emissions aren’t driving the climate towards a catastrophe, then we don’t need to analyze what happens during the catastrophe we probably won’t get. This applies equally to War, Pestilence, Famine, Drought, Floods, Storms, and Shrinking Fish (which, keep in mind, could have led to the ultimate disaster: shrinking fish and chips).
This way of looking at the climate is new for both scientists and policymakers. Until now, many of them have thought of the climate as a problem like no other; and best dealt with by trying to stop it (by reducing greenhouse-gas emissions). The new report breaks with this approach. It sees the climate as one problem among many, the severity of which is often determined by its interaction with those other problems. And the right policies frequently try to lessen the burden—to adapt to change, rather than attempting to stop it. In that respect, then, this report marks the end of climate exceptionalism and the beginning of realism.

The question then becomes NOT what is causing climate change or how we can prevent it, but rather: How much resilience can we afford?
Take this climate matter everybody is thinking about. They all talk, they pass laws, they do things, as if they knew what was happening. I don’t think anybody really knows what’s happening. They just guess. And a whole group of them meet together and encourage each other’s guesses.
