"Keeling said they have since redone the calculations, finding the ocean is still likely warmer than the estimate used by the IPCC. However, that increase in heat has a larger range of probability than initially thought — between 10 percent and 70 percent, as other studies have already found."
Now I'm no scientist, but when you have an error margin of 70% what possible relevance can the study have?
It looks like the scientists used a new/different way of measuring ocean temperatures:
...calculated heat based on the amount of oxygen and carbon dioxide rising off the ocean, filling round glass flasks with air collected at research stations around the globe.
Doesn't really seem like an ideal way to gather data, but maybe with a LOT of measurements you'd arrive at something usable. The article doesn't say how many measurements they took, so who knows .
