A creep instability analysis of the Antarctic and Greenland ice sheets
Creep instability, the runaway increase of temperature and deformation due to internal strain heating, is analysed with a very simple model of one-dimensional heat transfer to estimate the stability of the Antarctic and Greenland ice sheets. Derived stability maps indicate that for the assumed rheol...
