* A study published in Nature Climate Change earlier this month suggests that if the UK increased farm yields in line with what experts believe is possible, and turned spared land into forest and wetland, the resulting carbon «sink» could balance out the nation's agricultural emissions by 2050 — in line with government targets.

• About 20 percent of total current carbon emissions comes from land - use change.

Understanding how carbon flows between land, air and water is key to predicting how much greenhouse gas emissions the earth, atmosphere and ocean can tolerate over a given time period to keep global warming and climate change at thresholds considered tolerable.

These variations originate primarily from fluctuations in carbon uptake by land ecosystems driven by the natural variability of the climate system, rather than by oceans or from changes in the levels of human - made carbon emissions.
