In Episode 1: A Changing World, we see the changes that are upsetting the scientific predictions of the impact of climate change on the Arctic. Now, one sobering forecast is that the Arctic Ocean will be seasonally ice free by the summer of 2013. This possibility is what drives environmentalists to identify ways to minimize the changes affecting this snowy land. But for prospectors like Gordon McCreary, climate change brings new opportunities. He is part of the rush to claim the riches beneath the Arctic's ice: deposits of metals, gold, diamonds, and oil and gas.
