At the risk of stating the obvious, modeling the clouds correctly in the climate models is of some importance. It impacts longwave radiation cooling of the atmosphere (yes, longwave flux divergence in the atmosphere is typically negative), the incoming solar that reaches the ground, and incoming solar absorption by the atmosphere which creates heating.

I believe that we will continue to see anthropogenic warming, to some degree, for the foreseeable future. Whether it will turn out to be an existential threat is, in my opinion, to be determined. Those who believe we are facing an existential threat are probably basing it on climate model simulations and probably the 8.5 scenario. To be clear, there are a lot of uncertainties. Nobody knows for sure. As with almost anything that is complex, the odds of it happening are based on a probability function.

OK thanks, I guess that we can agree on the "indirectly" part. I was hoping that you might want to share an opinion on Dr DOOM's statement about Florida since it MAY (?) start affecting your golf game during increasingly HOT summers starting next summer. of course, if you are a snowbird then it would be just academic.
