I'm pessimistic about governments solving it through policy, but optimistic about science solving it. I'm particularly interested in technologies that sequester CO2, and I think this is a fantastic way to start setting prices for a carbon tax when things get worse. If all else fails, I've seen proposals for geoengineering that could work out in a reasonably short amount of time. I'd prefer if we solved it through being responsible (plant more trees, stop cutting down the rainforest, move to renewable energy, etc), but I'm not all that worried in general.
