Short summary
Is the fraction of anthropogenically released CO2 that remains in the atmosphere increasing? Is the rate at which the ocean and land sinks take up CO2 from the atmosphere decreasing? We analyse these questions by means of a statistical dynamic multivariate model from which we estimate the unobserved trend processes together with the parameters that govern them. We find no statistical evidence of an increasing airborne fraction, but we do find statistical evidence of a decreasing sink rate.
