Above figure 5: > During the last glacial period, Greenland experienced a sequence of very fast warmings (see Fig. 5). The temperature increased by more than 10°C within a few decades. Other records show us that major changes in atmospheric circulation and climate were experienced all around the northern hemisphere. Antarctica and the Southern Ocean experienced a different pattern, consistent with the idea that these rapid jumps were caused by sudden changes in the transport of heat in the ocean. So what you're seeing is not a 10-15 degree rise in global temperature, but an oversized effect on Greenland in one direction (while other parts of the world were experiencing different effects in different directions).a
