Despite Guy Callendar continuing to collect vital statistics on global warming, and publishing significant papers (such as one in 1961) his ideas met with dogged resistance from fellow meteorologists. Callendar explained this in a revealing note in his papers:

His fossil fuel theory was seen as too single-minded; ” the idea that man’s actions could influence so vast a complex [system] is very repugnant to some”; authorities in the past had pronounced against it, on the basis of faulty observations (which he had corrected); “Last, but not the least. They did not think of it themselves”.

Finally: ” CO2 as a cause of climate change… is above the heads of nearly all writers on the subject”‘
