Antarctica

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

It is obvious that only the heat generated by burning fossil fuels is saving us from another ice age.

sea levels are supossedly rising (due to Antarctic glacial melt), but Antarctic sea ice is expanding (because the weather down there is getting colder). and both are caused by human induced global warming. wow. magic !!!! I believe it, I really do !!!! quick, increase the carbon tax !!!

Maybe it’s expanding but it’s thinner? Let’s wait and see if it can support the weight of a penguin before we get too excited.

I agree!! Is there any way that we can possibly pay more towards the carbon tax?!? So that the government can use it to…um… You know, save the planet somehow by… making everything in Australia, which is already expensive, more expensive??

Increased sea ice as a result of increased melting of Antarctic continental ice is good news in as much as an increased area of ice will reflect more of the sun’s energy back into space and help slow the process of global warming. The question is, will this make a significant difference?

Sea ice makes no difference to sea level. More sea ice does not counteract the sea-level raising effect of the melting continental ice cap
