Research by biologists at West Virginia University, in the US state of the same name, has established that trees around the globe are consuming greater amounts of carbon dioxide than previously believed. This means that forests are even more important as carbon dioxide ‘sinks’ and play a much greater role in regulating the Earth’s atmosphere than has hitherto been recognised. Professor Richard Thomas and Dr Justin Mathias published the results of their research in the Proceedings of the National Academy of Sciences. They analysed carbon and oxygen isotopes in tree rings covering the period from 1901 to 2015. The samples were taken from 36 tree species at 84 sites from across the globe.
