Burying wood in 'vaults' could help fight global warming.

A recent study published in Science highlights the potential of using wood "vaults" as a carbon storage solution to combat climate change. The study examines the discovery of a well-preserved eastern red cedar log buried in eastern Canada for thousands of years, which demonstrates how burying wood underground can prevent the release of carbon dioxide into the atmosphere. Wood vaults, which involve burying biomass on land, have gained traction as a carbon sequestration method, with several pilot projects currently underway. The study estimates that burying 4.5% of the world's biomass could remove up to 10 gigatons of CO2 from the atmosphere annually. However, there are still questions about the long-term effectiveness and economic feasibility of this approach. The lead scientist suggests starting with burying waste wood to capture significant amounts of CO2 without encouraging deforestation. [Extracted from the article]
