There is a threshold of glacier extent reduction dependent on the magnitude
of ablation rate increase, where glacier runoff declines, the few examples suggest this is in the 10 - 20 % areal extent loss.
Comparison
of ablation rates and onsite temperature records in the case of the South Cascade Glacier, Easton Glacier, Ice Worm Glacier and Columbia Glacier yield a relationship between air temperature and daily ablation for snow and ice in SWE (Figure 1).

In the paper the authors argue that there is no evidence for a speed up
of the ice marginal zone due to enhanced
ablation rates, which by some people was explained as if Greenland was not contributing to sea level change any more.
Ablation rates in May at the start

They continue at a
rate set by the wind and the moisture gradient, and rob the glacier
of energy that would cause more
ablation if used for melting.
The surface mass balance observations similarly indicate that the ELA has migrated upwards at a
rate of 44 m / a over the 1997 — 2011 period in West Greenland, resulting in a more than doubling
of the
