Dear Sir,
Mr Bob Ward (letter, 5th May, ‘A roasting for climate claims’) is unlikely to be impartial on CO2, for he is Policy and Communications Director for the Grantham Research Institute on Climate Change and the Environment, an entity whose very existence (founded 2008) rests on the assumption that modern global warming (since 1900) is due to CO2 via the 19th-century idea of a so-called greenhouse effect.
