Occasionally, I get asked what is going on with the Antarctic. While the Arctic is warming faster than the global average1, the Antarctic seems to be doing its own thing (be it sea ice, temperature, ocean heat, penguins3) and it’s always slightly counterintuitive. This paper looks at one of the major influences on temperature in the Antarctic and the mid-to-high latitudes of the Southern Hemisphere, the Southern Annular Mode. It suggests that if one somehow removes the effects of the Southern Annular Mode then warming is more uniform across the hemisphere, which would be neat as it explains quite a lot.
