Renewable energy and carbon sequestration simply can’t move fast enough to prevent real disaster in Antarctic above all (and Arctic disaster sooner as a painful harbinger of bigger things). Buying 50 years would substantially increase our hope of doing the rest in time. In those 50 years, sheer exhaustion will also reduce the power of fundamentalists in the oil industry to keep us from saving our lives (and theirs!). Still, we do have a little time to work to develop other geoengineering options besides sulfate particles. If we had any sanity at all, we would be working very energetically to develop such options. This is not a game; if we don’t buy more time, we are ;probably dead.
