I'm sorry, but this statement in particular is incredibly stupid:
"It's possible that warming may actually add to the thickness of the continental ice sheets by increasing evaporation, which then falls as snow. This seems to be happening to both ice sheets. Is this part of a planetary homeostatic system that keeps things in rough balance? We simply don't know. Perhaps James Lovelock can ask Gaia about it."

If that's true, maybe the frost that formed on the microscope slide that I dipped into liquid nitrogen as the slide was heating up to room temperature was part of a 'homeostatic mechanism.' It couldn't possibly be a fully predictable consequence of the slide heating from very low temperatures to low temperatures to room temperature.

Also, increased evaporation = increased water vapor = increased greenhouse gas.

Also, increased evaporation = increased water vapor = increased greenhouse gas.

To finish your thought, I think you were trying to to imply, Increased greenhouse gas = Increased temperature.

How about, Increased water vapor = Increased clouds = Increased albedo affect = Increased cooling. Concurrent with Increased precipitation.

In fact, that is one of the many possibilities.

Mr Dunn was very accurate by bringing this (well-known) hypothesis into the article. I'm surprised you don't seem to be aware of its existence.

Also, increased evaporation = increased water vapor = increased greenhouse gas.

But, increased evaporation = increased cloud cover = increased albedo = lower temperature.
