George Hadley (1685 – 1768), an Age of Enlightenment citizen, lawyer and amateur meteorologist made a major contribution to climatology through an interest in the Trade Winds.
He worked inductively using ships weather logs to produce a theory about atmospheric circulation. Named after him, the Hadley cell is the only portion of the atmospheric circulation we understood in concept for 250 years. Its role is a major factor in global weather and climate yet is completely inadequately covered in Intergovernmental Panel on Climate Change (IPCC) computer models. The error in coverage exceeds any possible human impact and is one more factor causing consistently failed predictions.
