Zhu, Kai; et al. (2018): Limits to growth of forest biomass carbon sink under climate change

Zhu, Kai; Zhang, Jian; Niu, Shuli; Chu, Chengjin; Luo, Yiqi (2018): Limits to growth of forest biomass carbon sink under climate change. In: nature communications 9 (1), S. 2709. DOI: 10.1038/s41467-018-05132-5.

"To address both processes, we compiled a forest inventory dataset from North America to quantify aboveground biomass growth with stand age across forest types and climate gradients. Here we show, the biomass grows from 90 Mg ha–1 (2000–2016) to 105 Mg ha–1 (2020 s), 128 Mg ha–1 (2050 s), and 146 Mg ha–1 (2080 s) under climate change scenarios with no further disturbances. Climate change modifies the forest recovery trajectory tosome extent, but the overall growth is limited, showing signs of biomass saturation. Thefuture (2080s) biomass will only sequester at most 22% more carbon than the current level.Given such a strong sink has limited growth potential, our ground-based analysis suggests policy changes to sustain the carbon sink."
