Yesterday NASA reported that the Arctic ice is shrinking so much that it prompted a drastic change in National Geographic's Atlas. It is one of the most striking changes in the publication's history, geographers say. In my Postcard series, I look at the environmental threats to our arctic ice, rainforests, and cities. "Postcard From the Arctic" considers the shrinking Arctic ice sheet due to climate change and our compromised environment. Global warming affects the ice, the structure of the ecosystem, the survival of Arctic polar bears, and all of us.
