This blog has been posting weather conditions at Scott Base, Antarctica from The New Zealand Herald for some time now. The conditions sometimes look poor but most of the time look favorable. Note kindly that even though temperatures are subzero C, that does not preclude sublimination of the ice. Antarctica is entering into winter. This temperature is from today. It isn't as cold as it needs to be and where it is one needs to realize this is the bottom of Earth. There are some of the 3 mile thick Blue Ice that rarely is exposed to solar radiation regardless the time of year. Even then where the very bottom of Earth is below -90 C; there can still be sublimination if warm winds circle it. By every measure Antarctica is WARM.
