Ocean warming may be a major driver of sea-ice expansion in the Antarctic, researchers report today in Nature Geoscience1. While sea ice at the North Pole has shrunk substantially over the past three decades2, scientists have struggled to explain why sea ice near the South Pole has grown in extent over the same period3.

“The paradox is that global warming leads to more cooling and more sea ice around Antarctica,” says Richard Bintanja, a climate researcher at the Royal Netherlands Meteorological Institute in Utrecht. Bintanja and his colleagues show that enhanced melting of the Antarctic ice sheet — which is losing mass at a rate of 250 gigatonnes yearly — has probably been the main factor behind the small but statistically significant sea-ice expansion in the region.

Scientists have known for several years that meltwater from ice sheets can form a cold, fresh layer on the ocean surface that protects sea ice from the warmer waters below. But they were not sure whether that aided the observed expansion of Antarctic sea ice as the new study suggests.

Global warming has led to more ice in the sea around Antarctica and could help insulate the southern hemisphere from atmospheric warming.

A Dutch study says that unlike in the Arctic region, sea ice around Antarctica has expanded at a significant rate since 1985.

Published online in Nature Geoscience, the article suggests cool freshwater from melt beneath the Antarctic ice shelves has insulated offshore sea ice from the warming ocean beneath.

Richard Bintanja of the Royal Netherlands Meteorological Institute and colleagues say the Antarctic sea ice expands during southern hemisphere autumn and winter in response to this fresh, cool surface layer that freezes easily.

“Against the background of global climate warming, the expansion of Antarctic sea ice is an exceptional feature, which seems to be associated with decreasing sea surface temperatures in the Southern Ocean,” they write.

“We predict that this mechanism will be a sizable contributor to the factors that regionally and seasonally offset greenhouse warming and the associated sea ice retreat.”

They say the expanding sea ice may constitute a “feedback” that has the potential to oppose southern hemisphere atmospheric warming and amplify increases in global sea level.

Changes in sea ice can significantly modulate climate change because of its high reflective and strong insulating nature, the paper says.

as i have reported on for 6 months.. Antarctica is growing with ice..whilst the arctic sees to be losing some of its ice..but nobody ever discusses Antarctica because thats an inconvenient truth..now they have created some junk science to announce that global warming causes ice to increase in Antarctica..yes!..so by my reckoning that means it will annul the loss in the Arctic eh?..the wonder molecule..able to create droughts, floods, heat and cold..melt ice and freeze water..wow..just wow..

by their own admission..its a polar paradox..

  1. yeah lolled at this one too, for sure ;)
