We're all in agreement about the general benefits of forest permaculture but there is serious doubt about it's ability to draw down the enormous, problem-solving quantities of CO2 which this recent study seems to be claiming. There have been a number of threads on this before, like this one: http://members5.boardhost.com/xxxxx/msg/archive/1551617806.html If I remember rightly, the genocide of the American indigenous population was only partly responsible for the drop in temperatures, with the tilt of the earth's axis at that moment and unusual sunspot activity being attributed greater influence in a previous study. Note that the quote below does not refer to this latest study but to an earlier one: "Co-author Dr Chris Brierley believes there is. He said the fall-out from the terrible population crash and re-wilding of the Americas illustrated the challenge faced by some global warming solutions. "There is a lot of talk around 'negative emissions' approaches and using tree-planting to take CO₂ out of the atmosphere to mitigate climate change," he told BBC News. "And what we see from this [previous] study is the scale of what's required, because the Great Dying resulted in an area the size of France being reforested and that gave us only a few ppm. This is useful; it shows us what reforestation can do. But at the same, that kind of reduction is worth perhaps just two years of fossil fuel emissions at the present rate."..."
