There is more sea ice in the Arctic this summer than there was two years ago in 2012, a fact that has led to misleading stories that imply that there's more uncertainty about what's happening in the Arctic than there actually is. But comparing right now to two years ago and drawing conclusions about climate from those isolated data points is like saying "it's cold outside, guess we don't have to worry about global warming." It's an absurd comparison that doesn't take into account all the available information.
