Different Things are happening at the top and bottom of our world: Antarctica is gaining MORE ice, at the same time that glaciers are melting in the Arctic. What’s causing this strange discrepancy? The wind.
Changing wind patterns around Antarctica have caused a small increase in sea ice, as a result of cold winds off the continent blowing ice away from the coastline.
In the November 11th edition of the Guardian, Damian Carrington quotes researcher Paul Holland as saying, "Until now these changes in ice drift were only speculated upon using computer models. Our study of direct satellite observations shows the complexity of climate change.
"The Arctic is losing sea ice five times faster than the Antarctic is gaining it, so, on average, the Earth is losing sea ice very quickly. There is no inconsistency between our results and global warming."
Another part of the explanation is that Antarctica is a continent surrounded by an ocean, while the Arctic is an ocean surrounded by a continent, thus sea ice can’t expand the same way in the Arctic as it does at the southern pole, because if winds pushed the ice away from that pole, the ice would quickly hit land.
