Chart of the Day: Arctic Sea Ice

| Thu May 19, 2011 10:11 PM EDT

From the Arctic Sea Ice Blog, this chart shows the extent of (what else) Arctic sea ice by month since 1979, with trend lines drawn in. On current trends, the Arctic will be entirely ice-free in September by about 2016, and will be ice-free year-round by the early 2030s. Probably nothing to worry about, though. Who needs ice, anyway?
