Then, in 2012 or 2013, the IPCC will issue yet another report, the Fifth Assessment, in which the world's scientists will tell us, "We really meant what we said in all those other reports. Plus, it's even worse now because emissions are higher, so reductions would have to be far faster and deeper, and we've modeled the ice sheets better, so we're easily facing 3 feet of sea level rise by 2100, and we've modeled the carbon cycle feedbacks better, so the tolerable level of emissions is even lower than we thought in 2007."
By then, our ability to solve the climate problem the market-friendly way will have all but disappeared, and we will need a World War II-scale effort to avoid the ever-approaching catastrophe. By the end of the next decade, it won't just be climate scientists who are desperate, it will be all of us.
