According to an article posted by NBC.com, the levels of Arctic sea ice have shrunk to new lows covering an area less than have the size of the U.S. That can be significant for geo-political and economic reasons as well as climate and weather reasons. Our climate is controled to large extend by ocean currents and wind patterns. By melting the arctic sea ice, we reduce the amount of sunlight reflected back to space and increase the amount absorbed by the darker colored ocean waters. That in turn warms the air that blows over it which can then affect the weather patterns. It also thins the existing ice so that the amount of ice cover will vary much more over a shorter time period. The net result is our climate changes.
At the same time in an article published by Scoop Independent News, the amount of Antarctic sea ice is increasing...significantly. Why? Apparently ice that covers a continent such as Antarctica acts differently than ice that covers water such as in the Arctic. Both changes though will have an impact on our climate. Check out both articles for more.
