Interesting article. We should not underestimate advances in CO2 sequestration, or modest increases in nuclear and hydroelectric power. I'm more optimistic about renewable energies growth in the coming decades than the authors however (think computer revolution over the last 30 years; very similar science and technology are involved). Add to this improvements in energy efficiency (as has been happening steadily for decades), substitution of natural gas (with sequestration) for coal, and there is yet more cause for optimism. If we can meet a goal of keeping CO2 levels =< 500 PPM, a 1 - 1.5 temperature rise is within possibility.
I can't agree with Figure II's details. GW will not only shift the temperature curve, but should broaden it as well. This means extreme warm events will increase and the opposite decrease, but there will still be plenty (and more, albeit) of both.
Oh, please don't use pictures of cooling towers emitting plumes of steam. That has nothing to do with CO2 or warming (even ST plants have them), and can only confuse people. And phrases like, "global meltdown" really are misleading
