Unfortunately, CO2 also moves from the oceans and biosphere (and sequestered fossil fuels, due to our actions) into the atmosphere, which means you are talking about measuring a single interchange rate between various climate compartments, not total concentration changes in any one compartment.

The five - year mean global temperature has been flat for the last decade, which we interpret as a combination of natural variability and a slow down in the growth rate of net climate forcing.
