The melt is predicted in 30-40 years by the models.<quoted text>
My badÖthey did predict more snow. But they also predicted more melt due to CO2 forcing. So when someone says that an increase in Antarctic SIE is expected in a warming world, can you point out where that was expected and the models that came from?
As to your second question, try the paper that *you* posted that says the current increase is within the range of natural variability in the models.
