Regardless of how they are corrected it makes sense
This makes a _LOT_ of sense. Glacier ice retreat so far has been limited predominantly to the northern hemisphere. The retreat in the southern hemisphere is nowhere as pronounced. This in inconsistency is a subject of constant flamewars.
In the case of global WARMING due to greenhouse gas this difference is extremely difficult to explain.
In the case of global MELTING due to the albedo of the ice dropping like a stone things start making a lot more sense.
The temperate and polar zone air flows in the north and southern hemisphere are nearly perfectly isolated. To add insult to injury in the south there is an also little mix-up between the air masses across the inhabited temperate regions and the polar region because of the way roaring 50-es can go around the earth uninterrupted.
As a result any soot going up into the air in the north stays in the north and can be carried all the way into the arctic (no roaring 50-es in the northern hemisphere). Which in turn results in snow staying for much shorter during the winter (observed), glaciers retreating (observed) and arctic ice cap retreating as well (observed). None of that has been observed in the South. There you have a mixed bag. Retreat here, advance elsewhere.
This actually is a _MUCH_ worse scenario than global warming.
1. The sea rise from this is way faster than from global warming.
2. The models show that the worst case scenario for gulfstream interruption is actually in the case of change in ocean salinity due to excessive melting of ice.
So if this is the case we will actually see Europe sinking and frozen in our lifetime.
