We should research stabilizing our climate. Absolutely. But while we are at it, it would also be in our interest to make humans a multiplanet species, in order to protect us from a global extinction threat that isn't man made, as well. Super volcanoes, calderas (pretty much the same, I know), large meteor strikes.... none of these have anything to do with man made pollutants, and survival of the species is kind of a neat little concept, in my opinion =) Granted, we would probably become a new species in several thousand years, once we were off planet, due to the radiation and gravity differences, but hopefully the problem solving and intelligences would remain.
