People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Melt may explain Antarctica sea ice expansion

RATE THIS! +9
Posted in Science on 2nd Apr, 2013 01:17 AM by AlexMuller

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.

Ah so nay! And then they wonder why people don't much believe in this Global warming, Yes? They are so contradictory that no one knows what to believe. Yes? I do have one question though! Ice is heavy, if Antartic gets a lot more and arctic gets a lot less, isn't this going to cause a shift in Earths plane, make it roll over so to speak? Yes? Reply
