Heat transfer and meltwater flows in ice sheets

This post challenges the conventional framework for simulating meltwater flows on glaciers and ice sheets.


Increased melting rates due to potential increases in temperature would add liquid water directly into the oceans. An additional aspect is that the meltwater, on reaching the base of glaciers, might lead to increased sliding of the glaciers and the consequent calving at the terminus.

The World Resources Institute (WRI) has summarized the IPCC AR6 results regarding melting of Greenland and Antarctica ice:

Should warming reach between 2 degrees C (3.6 degrees F) and 3 degrees C (5.4 degrees F), for example, the West Antarctic and Greenland ice sheets could melt almost completely and irreversibly over many thousands of years, causing sea levels to rise by several meters.

The unity of government which constitutes you one people is also now dear to you. It is justly so, for it is a main pillar in the edifice of your real independence, the support of your tranquility at home, your peace abroad; of your safety; of your prosperity; of that very liberty which you so highly prize. But as it is easy to foresee that, from different causes and from different quarters, much pains will be taken, many artifices employed to weaken in your minds the conviction of this truth.  George Washington - Farewell Address

Two points:

a) bullshit.  In the miocene there were no ice caps - no glaciers anywheres - and yet somehow, when the present ice age started (yes, Virginia, the Earth is still in an ice age), the ice caps and glaciers all came back.

b) thousands of years - oh dearie me!!  The only people who won't be able to adapt to changes at that pace will be those benighted fools who waste all their time and resources on trying to stop the Earth from warming up out of its current ice age.
