paleoclimatologists

Another Dow friend recently cited to me the ice core samples from the paleoclimatologists, for example:

Nature paper: Eight glacial cycles from an Antarctic ice core

Anyway, as a right-leaning dude, his observation was that we should hope that the current global warming trend (and the ice age it might trigger) have human orgin because that means we can do something about it. Otherwise, we're toast.

Polar Ice Loss

JM,

Sticking with the "sun as culprit" theme. I wonder if polar ice loss is especially indicative of a solar effect. My earlier post cited scientific studies of other locations, some of which had increases in ice coverage. Thus ice loss is not uniform as one might expect in the case of an atmospheric cause.

I'm thinking of the magnetosphere and the field lines directing charged particles (higher energy particles) to the poles.

Would be nice if our resident physicist would grace us with a comment, Bob?
