Just another brick in the wall of “settled science.” Daily Mail:

Climate change may not be as catastrophic for Greenland’s icecaps as scientists first thought after researchers found hotter summers may actually slow down the flow of glaciers.
Increased melting in the warmer summer months is causing the internal drainage system of the ice sheet to ‘adapt’ and accommodate more melt-water, without speeding up the flow of ice toward the oceans.
This is because in hot conditions there is initially so much melt-water that it runs off into channels below the ice, thereby decreasing the lubricating layer which sits on top of the ice sheets and causes melting over a much larger surface area.
Owing to this, the acceleration of melting appears to stall early on in hot summers, whereas it does not in cool ones.
The findings, reported in the journal Nature, have important implications for future assessments of global sea level rise.
