The ideal approach would be a "just-in-case" climate-change mitigation plan. If global warming stays at or under current baseline projections, we probably would do best to simply just adapt. However, if global warming accelerates, we would want to take strong steps to counteract it.
I'm of a similar mind, although to me, the best "just in case" thing to do requires decades of construction, that is, a massive increase in the number of Nuclear Powerplants. I say we start now, hedging our bets.
Agreed.
