Preparing for the effects is much more practical, and something that you can execute against. I have long been a proponent of the notion that there is ample, and incontrovertible, evidence of climate change even before people started adding their own hand to the mix. As such, the expected value of a dollar spent on preparing for a change in climate gives a better return in terms of survivability than spending a dollar changing a local contribution to CO2 production. Spending money on both is even better.

When one of the super volcanoes burps its going to screw up a lot of things, and it would be nice to have some options.
