Iddo Wernick, our long-time collaborator Pekka Kauppi, and other forestry experts published Quantifying forest change in the European Union in Nature vol 592 pages E13–E14 (2021). The authors argue that net carbon stored in the EU continues to increase as forest volume accumulates faster than additions to (and fluctuations in) the annual harvest.
