Longterm, we will have to find some kind of climate control. The last ice age was not too long ago, but mankind has almost entirely lived without. A return of the glaciers would be even worse than global warming (in my estimates), and extrapolating the curves shows that the next ice age is due (were it not for the fact that we changed the atmospheric composition sufficiently to avert that for sure). Right now we already are playing around with the climate, but very uncontrolled and destructive. I'm also not in favour of using methods designed for climate control in our situation due to the risk (which is different for the different methods, and the failure results are very different also, but still) - the better solution is clearly to stop emitting CO2 - but longterm, we will need the knowledge. Best to test it on another planet first..
