"ONLY GEO-ENGINEERING CAN SAVE US"

This report by (you've guessed it) geo-engineers, makes the claim that CO2 reductions will not be enough to save us from the ravages of global warming. It is interesting to note that there are geo-engineering solutions, and my thinking is that if they exist then we can save them for the time when they are needed, instead of wasting countless billions in a futile attempt to reduce emissions of CO2.
