Every once in a while I put up something from Real Climate, an organization of climate scientists. This entry shows very visibly how climate is changing over time.
Graphics with solid verbal explanations can convince me reasonably well. Most projections suggest that the arctic regions will warm most, followed in turn by the northern middle latitudes. That's what the pulse distribution shows. Then comes the Antarctic region which includes Antarctica itself and the ocean abutting it. But he tropical and subtropical regions are warming some. Lagging is the upper-middle latitudinal zone of the southern hemisphere, but that is almost entirely ocean, water surfaces generally gaining less in temperature due to the heat capacity of water.
The ice sheet atop of the Arctic Ocean is known to be shrinking, and climate maps show this. The July monthly isotherm of 50F in northern climatic zones that serves as the usual boundary between non-polar and tundra climates has moved away from Reykjavik; Nome, Alaska is now just barely out of the tundra climate zone.
But not even the ferocious winds (the Roaring Forties, Furious Fifties, and Screaming Sixties) and the strong Antarctic Current surrounding Antarctica can fully shield Antarctica from global warming, as is shown by the calving of some ice shelves on the Antarctic Peninsula.
