Timber!

Forests are essentially an enormous carbon store. Trees hold more than 860 gigatons of carbon. This is roughly equivalent to an entire 100 years of fossil fuel emissions. A study in Nature Sustainablity opines, however, that this Century's carbon emissions from tropical deforestation were previously grossly underestimated (https://www.theguardian.com/environment/2022/feb/28/deforestation-emissions-far-higher-than-previously-thought-study-finds-aoe). The newer study reckons that tropical deforestation has doubled in the last 20 years. The study suggests that such losses are continuing to accelerate. In the past, it was difficult to obtain accurate data, due to the a) remoteness of locations and b) lack of openness by officials. Tropical deforestation appears to be yet another dangerous accelerant for the climate crisis.
