Let me put a final question to you gentlemen, if I could.
In the Summary for Policymakers, which I have here in front of me, you're right that there's absolutely nothing here in terms of policy. It's pure science. But is your work in this report predicated on a fundamental understanding that if we're going to deal with climate change, we have to first understand that there may be 184 nation-states, but there's only one atmosphere; and that perhaps the greater the proximity of cooperation between those 184 nation-states, the better the chance we're going to have in dealing with the reality of global warming with one atmosphere? Is that a fair assessment of what you have come to, as scientists, in terms of conclusions?
