Sinking trees into the Arctic Ocean might reduce carbon emissions
A modelling study proposes removing mature boreal trees, floating them down Arctic rivers and sinking them in deep Arctic waters while replanting fast‑growing trees; the authors estimate this could sequester about one gigaton of CO2 per year if done on roughly 1% of the boreal forest. The article notes major logistical, ecological and social uncertainties and compares the potential removal with global emissions of 37.8 gigatons in 2024.
