报告摘要：

Lands represent a prominent control on the global carbon cycle and considerable uncertainty and debate currently exist in projecting the future capacity of lands to sequester atmospheric CO2. In this talk, I will focus on forests and first present the paradigm of the fast paradox with ‘faster tree growth, faster mortality and shorter carbon turnover time’, thus challenging the traditional view of increased forest carbon storage in a future CO2 enriched atmosphere. I will then show how the field-based tree mortality data can be used to reduce the uncertainty of model-projected forest carbon sinks in a future climate. Thirdly, I will synthesize the worldwide empirical evidence and develop a mathematic framework to demonstrate the increased risks of catastrophic carbon loss over a shorter timescale facilitated by faster biota responses in the Anthropocene. Finally, I would conclude by sharing my insights on how game theory and tragedy of commons could be leveraged to assess the fast paradox and land carbon sequestration in the Anthropocene.
