A Vanishing Arctic and National Security

These videos are from November, but I stumbled upon them today and wanted to share. This is a TED address by US Navy Chief Oceanographer David Titley, former climate skeptic, who talks about climate change as "one of the preeminent challenges of our century." For years he watched the issue grow prominence as politics started to take it over. "But the evidence kept mounting," he says.

In this second video, he gets into details about national security with a particular focus on the Arctic. "By the middle of the century, you'll start to see two to three months of ice-free conditions. Once you get that amount of ice-free time, the big shippers of the world are going to start really paying attention," he says. "I can tell you that the people of Iceland are thinking right now, how do they become the Singapore of the 21st century."
