| Summary: | As counter-intuitive as it sounds, Dr Jan Lieser, lead author of the ACE CRC report, told me the increase in sea ice is consistent with the changes in a warming world.The sea ice is sitting at the interface of the ocean and the atmosphere, and so it gets a double-whammy effect. We actually understand the physics of this quite well. It is because of the warming that we can see the sea ice increasing at the moment.Speaking from Hobart and an international gathering of scientists to discuss polar sea ice, Dr Lieser said the picture of change in the Antarctic was complex.But he said increased wind, wave and storm activity in the Antarctic helped to stir up the waters, creating ridges and rifts that helps sea ice to thicken.
