Seasonal exchanges are huge: about 20 % of all CO2 in the atmosphere is exchanged between atmosphere and other reservoirs over the seasons, but as the exchanges with oceans and vegetation are countercurrent with temperature (vegetation in the NH dominates), the net result is only some 2 % change in the atmosphere over the seasons which is visible in the Mauna Loa curve.
