SOLAS-IMBeR Interior Ocean Carbon working group, led by Niki Gruber, has determined the amount of man-made CO2 emissions taken up by the ocean from the atmosphere between 1994 and 2007.
The state of ocean CO2 uptake
The ocean is an important sink for anthropogenic CO2. From the beginning of the industrial revolution to the mid-1990s roughly 30% of our emissions have been absorbed by the oceans. This process is an important moderator of climate change, but can we count on it to remain as strong in the future? Gruber et al. calculated the ocean uptake of anthropogenic CO2 for the interval from 1994 to 2007, which continued as expected. They also observed clear regional deviations from this pattern, suggesting that there is no guarantee that uptake will remain as robust going forward
