The mainstream climatologists are fond of telling us that additional co2 increases the 'Effective Height of Emission' of radiation to space by 'Greenhouse Gases', and that this must cause a rise in surface temperature because the lapse rate from the average temperature of 255K at the 'EEH' to the surface will mean a higher temperature. Hess proposed that continents do not move through oceanic crust, but that continents and oceanic crust move together as a single unit.
