Global Warming is supposed to have greater effect in polar regions, but for some time the apparent refusal of the South Polar region to comply has been of some interest. Sea ice area increase can be explained away by various mechanisms, but actual temperatures are more difficult to explain.
Using UAH V6.0 data, here is the graph of the Temperature of the Lower Troposphere (TLT) for the South Polar Region, below 60 degrees South, since satellite records began in December 1978.
For as long as we have records, Antarctica has not warmed at all. The trend is -0.04 degrees Celsius (+/- 0.1C) per 100 years. Zero trend, (or slightly cooling if you want to annoy your Global Warming Enthusiast colleagues).
