In a similar vein to previous tree-planting reports, a recent study has concluded that tree planting will not affect climate change. With high carbon dioxide, the limiting factor in plant growth becomes nitrogen – and atmospheric levels aren’t rising fast enough. This is a bit of a mixed blessing – while we are undoubtedly screwed regarding atmospheric carbon, governments might not be able to use their tree planting as an excuse for not implementing renewables anymore.
