There is no practical way to get carbon dioxide levels down to 350 [parts per million in the atmosphere] without the annihilation of large numbers of people and collapsing economies. When the 1.6 billion people in developing countries raise their standard of living, what we do here and in Western Europe is not going to have any real effect. We're going to have higher emissions for the next several decades in spite of anyone's efforts. If that's the reality, then we have to deal with it. If people believe that going above 450 ppm is going to cause an environmental calamity, then we'd better spend more resources on adaptation, because it's almost inevitable that we're going to go beyond that level.
