Understanding Climate-Carbon Cycle Feedbacks: Impacts on Carbon Balance and Uptake

This study investigates the interactions between climate and carbon cycle feedbacks, utilizing the LPJ-GUESS model in offline simulations. It emphasizes the effects of biogeophysical feedbacks on carbon uptake, noting that the range of carbon uptake amounts to approximately 50% of the current atmospheric CO2 levels. The research highlights the importance of seasonality and addresses robustness and uncertainty in carbon cycle responses. The findings are crucial for improving forecasts of climate change impacts on carbon dynamics.
