Ninety scientists ask feds to protect carbon-rich old forests in upcoming climate plan, March 23; Letter, Managing forests is critical in the face of a changing climate, March 29. Kate Lindsay of the Forest Products Association of Canada fails to acknowledge either the large net carbon emissions from logging or the view of numerous scientists that clear-cutting forests is unsustainable. Younger trees sequester carbon faster, but it takes centuries for regrowth to pay back the emissions from logging. Canada is both failing to follow the Intergovernmental Panel on Climate Change’s requirement to report all forest carbon fluxes and claiming excessive credit for sequestration. We encourage industry leaders to engage with serious scientific concerns on these issues, not jump to dismiss them.
