provide the first global estimate of how much of the CO2 emitted from land has been offset by regrowth, using a model of CO2 sources and sinks in terrestrial ecosystems. To cover a range of
possible land-use changes that may have taken place, they used four different scenarios. They found that even extensive human interference caused the net loss of only 1.1–1.3 billion tonnes
of carbon per year in the 1990s — about half previous estimates. One factor that may explain this, they say, is the 0.35–0.6 billion tonnes of carbon absorbed annually by plants growing back
after disturbance, mostly in tropical forests. This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your institution Subscribe to this
