The Autumn leaves of Red and Gold

It had been hoped, that global warming would delay the onset of Autumn in our forests but a recent study suggests that trees actually drop their leaves earlier (https://www.theguardian.com/environment/2020/nov/26/climate-crisis-making-autumn-leaves-fall-earlier-study-finds). This results in the trees storing less carbon. So, planting trees will have less impact in terms of removing atmospheric carbon dioxide. It has been estimated that the early dropping of leaves, means that annually 1 billion tonnes of carbon dioxide less will be stored in trees. It calls into doubt the rather simplistic idea that, planting more trees, will reverse the effects of climate change.
