-- First we increase the greenhouse gases — then that causes warming in the atmosphere and oceans — as the oceans warm up, they evaporate more H2O — more moisture in the air means more precipitation (rain, snow)-- the southern hemisphere is essentially lots of water and a really big ice cube in the middle called Antarctica — land ice is different than sea ice — climate models
indicated that more snowfall would cause increases in the frozen H2O — climate models
indicated that there would be
initial increases in sea ice extent —
observations confirm the indications and expectations that precipitation is increasing, calving rates are accelerating and sea ice extent is increasing.
