The Littlest Arctic

New World Record. Last month the Arctic was the smallest we've ever seen it. This graph shows the yearly cycle. Ice melts in the middle (summer) period, then builds back during the rest of the year. But each year it's getting smaller.

The black dots are the 30-year averages. The crosses are 2007 and the 2 blue lines are the last 2 years. September 2011 was the lowest point so far, as we get closer to having no arctic ice.

So here's your chance to play amateur-scientist. Using this and other recent graphs at the Arctic Sea Ice Blog - make a prediction. When do you think the Arctic will first lose all its ice?
