Why has the amplitude of the seasonal cycle in the NH increased? By Rebecca Thomas

Observations show that the amplitude of the seasonal cycle (SCA) of atmospheric CO2 in the higher latitudes of the northern hemisphere (45N-90N) has increased by 57±7% over the last 50 years. The seasonal cycle at these latitudes can be almost entirely attributed to land regions between 30-90N (Graven et al. 2013). However, terrestrial biosphere models … Continue reading Why has the amplitude of the seasonal cycle in the NH increased? By Rebecca Thomas
