"In Antarctica there has been a small increase in winter sea-ice extent due to changes in Southern Ocean winds. There is considerable regional variability, with some regions showing significant decrease in winter ice and in the length of the ice season."
There is a difference between sea ice and ice mass. The article is dishonest as it wrongly infers that the two are the same. The Antarctic ice mass is declining, despite the growing sea ice, and will cause higher sea levels if the trend continues.
