From 1978 onward CRU began production of its gridded data set of land air temperature anomalies based on instrumental temperature records held by National Meteorological Organisations around the world. In 1986 sea temperatures were added to form a synthesis of data which was the first global temperature record, demonstrating unequivocally that ...
