One of the most popular global warming feedbacks is considered to be changes in the extent of polar ice. The story goes that as the ice melts, more heat gets absorbed in the ocean, leading to higher temperatures. Today we test that theory.
According to NSIDC, Antarctic ice extent is nearly 20% above normal, as seen in the graph and map below.
If the theory is correct, the large amount of excess ice should be cooling Antarctica – and that is exactly what we see happening. Temperatures in Antarctica have been running persistently below normal, as seen in the maps below.
There is just one problem with all this. The effect is exactly opposite of what has been predicted by global warming modelers. Antarctic ice is increasing and temperatures are cooling.
