1: ALBEDO FEEDBACK
‘Albedo Effect’ – reflectivity-absorption-melting feedback. As the temperature goes up, more snow melts, decreasing summer albedo, increasing warming – accelerating melting

2: MELTWATER LUBRICATION FEEDBACK
‘Meltwater lubrication feedback’ – warming of the atmosphere causes ice sheet surface melting. Before this meltwater runs to the sea, it can also speed up glacier movement, accelerating sea level rise

3: ICE HEIGHT FEEDBACK
Diminishing ice sheet altitude feedback working on temperature, meltseason lengts & snow accumulation – easily overlooked, but a sensical Grand Final to full collapse(!)

4 & 5: ICE SHELF COLLAPSE FEEDBACKS
Here we take two in one: the (basic) ocean warming and sea level rise* ice shelf feedback. (There are more complicated ice shelf feedbacks, as we’ll find out later!)

6-8: BIPOLAR SEESAW FEEDBACKS
Greenland-Antarctic bipolar seesaw, Dansgaard-Oeschger & Heinrich Events: hemispheric asynchrony as a mechanism for accelerating net ice sheet disintegration and sea level rise

9: VOLCANIC ICE MELTING FEEDBACK
Isostatic rebound volcanology melting (and CO2) feedback

10 & 11: ICE CLIFF COLLAPSE (& HYDROFRACTURING OF ICE SHELVES)
Again, we pile together two ice sheet melting feedbacks (as they’re never as clearly defined) – both illustrating a mechanism for increased glacier flow and ice melting at the ice sheet marine margin.

12 & 13: SOUTHERN OCEAN ‘COLD LID’ MELTWATER FEEDBACK
We get to the new Hansen study and can again pile two additional amplifying feedbacks together: a Southern Ocean meltwater surface ‘cold lid’ that promotes heat build up directly under ice shelves (and increases the Earth’s energy imbalance, amplifying the net warming)
