Takes too long before definitive proof comes in.
I haven't heard of anyone predicting that computers would bring about the "paperless office" losing his job. Nor those who were predicting that by the 80s, productivity gains would be such that no one would have to work full time, and the main demand for labor would be for psychotherapists to help the masses deal with all that free time. (Yes, I read that in a newspaper back in the 70s! I remember because it was so patently ridiculous it was hard to forget.)
Of course, maybe they didn't lose their jobs because no one can remember who they were. ;-)
Anarctica has been frozen for at least 35 million years.
There have been lots of warm periods since then and yet the ice remains.
The bulk of scientific studies show there is no net loss of glacial ice across the continent. Some ice shelves are losing mass while others are growing. The actual temperature records show some areas warming, some areas getting colder. As you would expect.
Here is a link to the temperature record for the actual South Pole since 1957. The average temperature has fallen by about 5 deg. C to minus 50 C.
(might have to cut and paste into the address bar to get the link.)
