Carbon emissions from tropical deforestation this century are far higher than previously thought, doubling in just two decades and continuing to accelerate, according to a study.

The world’s forests form an enormous carbon store, holding an estimated 861 gigatons of carbon – equivalent to nearly a century’s worth of annual fossil fuel emissions at the current rate. When trees are cut down, they release the carbon they store into the atmosphere. Since 2000, the world has lost about 10 percent of its tree cover, becoming a major driver of global heating.

Yet, despite being the second largest human source of greenhouse gasses after fossil fuels, the carbon accounting behind emissions from land still contains significant uncertainties, often relying on limited data that poses difficulties for researchers tracking progress towards meeting the goals of the Paris agreement.

A study published on Monday in Na... Read more
