> I think "doing nothing" is what people who advocate reduction of consumption and having fewer kids are doing. What I'm advocating is technological development to solve the problems related to global warming.

You may think so but that's not the case. I don't know of too many vegan-organic-bike-riding-hippy types who think we shouldn't invest in grid-scale storage, renewable power, carbon capture, or more efficient heating & cooling, manufacturing, or transportation systems. Arguably the only tech many of them oppose is nuclear power.
