Respiratory loss during late-growing season determines the net carbon dioxide sink in northern permafrost regions

Z. Liu, J. S. Kimball, et al.

This research by Zhihua Liu and colleagues explores the intricate dynamics of CO2 uptake and respiration in northern high latitudes, revealing how increased tree cover significantly slows annual net CO2 uptake due to heightened late-growing season respiration. The study scrutinizes existing vegetation models and highlights the seasonal compensation effects critical to understanding net CO2 trends under warming conditions.
