The contribution of land-use change versus climate variability to the 1940s CO2 plateau: Former Soviet Union as a test case" In this study, authors attempted to explain why the stabilization of atmospheric CO2 concentration was observed during the 1940s.Earlier, Bastos et al. 2016 have showed that the global CO2 budget in terrestrial ecosystems during this period has a gap sink of 0.4-1.5 PgC yr-1.To explain this gap, authors made 2 hypotheses: (1) huge land-abandonment due to the socioeconomic and demographic disruptions during World War II that might lead to an additional C C1
