  28. Emissions are rising faster than the time scales regulating the rate of uptake by sinks. Sinks are becoming less efficient at high CO2 Land: saturation of the CO2 fertilization effect Ocean: decrease in [carbonate] which buffers CO2 Land and/or ocean sinks are responding to climate change and variability. We are missing sink processes in models that are contributing to the observed changes. Possible Reasons for a Positive Trend in Airborne Fraction

  37. The efficiency of the natural sinks has being declining over the last 60 years, a trend not fully captured by climate models. The human perturbation of the carbon cycle continues to grow strongly and track the most carbon intensive scenarios of the IPCC. The economic crisis will likely have a transitional impact on the growth of CO2 emissions and a undetectable effect on the growth of atmospheric CO2 (because the much larger inter-annual variability of the natural sinks).
