Climate change is expanding Antarctica's sea ice, according to a scientific study in the journal Nature Geoscience.

The paradoxical phenomenon is thought to be caused by relatively cold plumes of fresh water derived from melting beneath the Antarctic ice shelves.

This melt water has a relatively low density, so it accumulates in the top layer of the ocean.

The cool surface waters then re-freeze more easily during Autumn and Winter.

This explains the observed peak in sea ice during these seasons, a team from the Royal Netherlands Meteorological Institute (KNMI) in De Bilt says in its peer-reviewed paper.

Climate scientists have been intrigued by observations that Antarctic sea ice shows a small but statistically significant expansion of about 1.9% per decade since 1985, while sea ice in the Arctic has been shrinking over past decades.

The researchers from the KNMI suggest the "negative feedback" effect outlined in their study is expected to continue into the future.

They tried to reproduce the observed changes in a computer-based climate model.

The sea ice expanded during Southern Hemisphere autumn and winter in response to the development of this fresh, cool surface layer, which floated on the denser, warmer salty sea water below.

This fresh water is ultimately derived from enhanced melting at the base of the Antarctic ice shelves.
