An interesting article over on the Air Vent site where they are a bit bemused that the figures for total carbon don't stack up.
Carbon is going missing. We know to a reasonable approximation how much carbon is being emitted to the atmosphere by burning fossil fuel and land use changes. But the concentration in the atmosphere isn’t going up as fast as expected. Where is it going and what will be the long term effect? I don’t have the answer, but I’ve learned some things by looking at the data that weren’t obvious in relation to what I’ve previously read about the carbon cycle. This is important, because any strategy for stabilization of atmospheric CO2 is completely dependent on our understanding of the carbon cycle.
Is Al Gore nicking it I wonder?
Maybe that the IPCC are using the wrong equations.
Anyway. Go and read it all over at the Air Vent.
