The amount of snow/ice which accumulates on Greenland’s surface is much greater than the amount of melt. This autumn, accumulation is at a record high.
Some skeptics fall into the trap of believing alarmist BS about “total mass balance” and “basal melt” Those are things which can’t be measured accurately, and are a response to the surface mass balance. If the amount of ice accumulating on the surface increases or decreases, then the amount of ice flowing to the sea will eventually adjust to match the surface mass balance – and return to steady state equilibrium. Over the long term, the amount of snow accumulation, melt and glacial loss has to be a net zero.
The only interesting long-term metric is the surface mass balance. which shows that more snow falls on Greenland’s surface every year than melts from Greenland’s surface. This tells us that Greenland is absolutely not melting down. It is possible that there is a temporary imbalance between accumulation and calving, but this will eventually adjust back to a net zero.
