Case 1 : Man-made emissions are slowing aggregating in the atmosphere, but the natural component is rising realtively equally thus keeping our bit the same Case 2 : The man-made component is being absorbed. If case 1, if the initial split is 20/80, and our bit increases 20% to 22%, that means that the natural bit had to increase by 8%, in order to keep the ratio 20/80 and thus not change our part of the contribution. If case 2, where is the CO2 going suddenly, and why isn't overall atmospheric CO2 levels reducing? Don't even suggest the idea that it just so happens that mans emissions just happen to balance the rate of absorbtion. Best regards, Vulcan. |

45% of our emissions stay in the atmosphere, this research concerns itself with the remainder, that is absorbed by the oceans. Some have postulated that the oceans are already begging to become saturated.
It suggests, if the research is valid, that the oceans are better at absorbing excess CO2 emitted by ourselves than thought. But they will reach saturation point, if it's not happening yet, it will soon. The oceans can't continue to absorb the product of our folly, they have a limited capacity.
All it means is that our prediction for when the oceans would reach saturation point is a bit off. That point will be reached, and when it is, the concentration of CO2 in the atmosphere will increase rapidly, because the oceans won't be capable of absorbing any more.
Lets hope the signs that it's begging to happen now, are indeed premature, it gives us a bit more time, not much, but perhaps a bit.
