Oceans taking up less carbon

This is not encouraging: in the last 10 years the oceans have been taking up significantly less carbon dioxide than they once did: 50% less in the North Atlantic, since measurements began about 10 years ago.

The researchers who did the study admit they can't attribute this to human-caused climate change -- they simply have no baseline against which to compare, and it's possible there are significant natural fluctuations in the ocean's ability to absorb carbon dioxide. Definitely something to keep an eye on. If the ocean sink saturates climate change is going to happen even that much faster.
