Protecting existing forests so they grow to maturity could theoretically remove as much as 228 billion tonnes of carbon from the air, according to a team made up of hundreds of researchers. This is equivalent to removing around a third of the carbon humans have added to the atmosphere to date, but critics say it is unlikely we could actually achieve this level of carbon absorption .
The finding will fuel a heated debate over the role of trees in mitigating climate change, which was ignited by a 2019 study overstated this potential by as much as five times by counting areas like deserts where growing trees would be impractical or by failing to account for other factors, such as fire., which can have disastrous effects for biodiversity and local people even as they store carbon. Crowther says the emphasis on tree-planting “massively oversimplified” the message and was damaging. “This scientific controversyIn an attempt to move beyond the controversy, Crowther and more than 200 colleagues took another look at the carbon storage potential of Earth’s forest

Forests with multiple tree species are 70% more effective as carbon sinks than monoculture forests, study findsTo slow the effects of climate change, conserve biodiversity, and meet the sustainable development goals, replanting trees is vital. Restored forests store carbon within the forest's soil, shrubs, and trees. Mixed forests are especially effective at carbon storage, as different species with complementary traits can increase overall carbon storage.
