Climate Change and the Arctic

Global warming extent

The article "Arctic Wintertime Sea Ice Extent is among Lowest on record" by Marie Jose Vinas talks about the annual winter time peak. The arctic sea reached a maximum of 5.59 million square miles of ice surface cover making it the second lowest on record, only beaten by last year's record by 23,200 square miles. Annually, the ice in the Arctic thickens and thins over the year and the past 4 years have seen the Arctice ice cover diminish slowly.

Goodbye Sea Ice = Goodbye Polar Bears

Imagine being responsible for the extinction of the world’s largest bear species. A bear species that has adapted to surviving in the harshest environmental conditions, yet is threatened by the activities of humans. This article tells us that within the coming years, the human contribution to climate change and the effects of this environmental phenomenon may ultimately make this tragedy a reality for the polar bear.

Arctic amplification: not just an issue for the polar bear.

Common to the issue of climate change in the Arctic is the photo of a polar bear on an ice floe. While polar bears certainly are suffering as a result of climate change other Arctic species should not be forgotten. An article from the CBC by Bob McDonald summarizes two interesting reports on the climate change impacts on caribou and Arctic flora. According to the article, endangered Peary caribou are having to spend increasing amounts of time and energy travelling between islands due to a reduction of sea ice between the islands as a result of climate change.
