Of course what is the best way to minimise the risk is a question for debate. Personally I think we should be investing a massive amount in energy R&D and efficient ways of extracting the CO2 from the atmosphere so if we do start to slip into a runaway greenhouse event we are in a position to do something about it. If we just continue along the path we are on (do nothing) if something catastrophic does happen we will not have the tools to respond.
