Currying confusion

Dr. Judith Curry is chair of the School of Earth and Atmospheric Sciences at Georgia Tech, and has an extensive background in studying Earth's climate, particularly regarding changes in storms, hurricanes, and the like under changing climate conditions. She recently coauthored what seems a very interesting paper on the growth of Antarctic sea ice - apparently the effect of a moderate degree of warming such as we've seen so far is to actually increase sea ice extent in the southern ocean, thanks to increased precipitation in the form of snow. Higher sea temperatures mean more evaporation of water (mostly closer to the equator) which in turn leads to higher levels of precipitation (mostly further south), and if it's cold enough to snow, then paradoxically the result is actually more ice on the water surface, not less.
