Here is an interesting story about the moving melting ice at the North Pole. While the denialists deny, the ice just keeps disappearing. Arctic researchers are investing in floating buoys to study polar ocean dynamics now. But here's my favorite line from the article:
"...the ice is not a uniform cap, as it might appear on a chart, but a milling mass of floes that are in near constant motion. While we were there, the ice beneath our feet was moving about 400 yards an hour. That’s why the sign that the team set up had to be changed from “North Pole Is Here” to “North Pole Was Here” after a couple of days."
Let's hope it doesn't say "polar bears once lived here" any time soon.
