Thank you very much. Permit me to répondre en anglais.
One of the things the IPCC Working Group I report is saying is that indeed there is inertia in the climate system. We are seeing impacts now and we can expect to see impacts continue for the next two, three, or possibly four decades. What that says is that in fact the history is already written, and therefore we have some obligation to respond to those potential impacts. An adaptation no longer is simply a policy option; in my view, it now becomes a policy imperative.
Having said that, however, I think we have to be careful not to use adaptation as an excuse not to reduce our emissions. We have to understand that the root cause of the problem, as Professor Weaver was saying, is human emissions that are changing the balance of the climate. It is important to recognize that emissions have to be reduced not by 6% but possibly by as much as 60% if we're going to stabilize the concentrations and stabilize the climate at a level that is not dangerous to our livelihoods.
