The great ice sheets are melting with increasing velocity. Melt ponds are forming over Greenland, then pounding heat down through the ice like the smoldering hammers of ancient Norse fire giants. Warming mid-depth ocean waters are eating away at the undersides of Antarctica’s great ice shelves. Pools of fresh water are expanding outward from the bleeding glaciers, flooding the surface zones of the world’s oceans. Sea level rise rates have jumped to 4.4 millimeters per year (see study here). And the North Atlantic Overturning Circulation (AMOC) is slowing down.
Keeping all this in mind, let’s talk a little bit about the ugly transition to phase 2 climate change. A transition it now appears we’re at the start of. The — you should have listened to Dr. James Hansen and read The Storms of My Grandchildren — phase of climate change. The awful, long, stormy period in which the great glaciers really start going down.
In an effort to organize how human-caused climate change may proceed, it helps to break the likely progression of human-caused climate change down into three basic phases. For this simplification we have phase 1 — polar amplification, phase 2 glacial melt and storms, and phase 3 — runaway hothouse and stratified/Canfield Oceans. For this article, we’ll focus mostly on phase 1 and 2.
