The actual decrease in (year-round average) albedo wouldn't be as significant due to seasonal snow/ice cover, but as solar energy is massively concentrated in the summer at Antarctic latitudes, the effective albedo would still be much less. Topography and other effects allowing warm ocean currents and air masses to move southward. The general warming of the Antarctic would cause the maximum-density Antarctic Circumpolar Current to move southward, with subtropical currents such as the Brazil, Agulhas, and East Australian currents pushing southward and providing a Gulf Steam-like influence. The lower elevation of the interior would also allow (warm) weather fronts from lower latitudes to penetrate deep into the continent. As implied all throughout this, there would be negative feedbacks causing reglaciation, and said glaciation would stop at some point, but the point of contention is when and where, i.e. how negative the second derivative of glacial area is. So, with all the factors taken into account, what would be the answer? Is Barry Lewis correct or not?
†This was roughly calculated by combining solar angle with the Stefan-Boltzmann law at the albedo of open water, with an estimate of the atmospheric absorption and reflection given absolutely ideal atmospheric conditions adjusted by angle.
