A method is provided that enables aircraft to contribute to global cooling by flying at select locations, altitudes, and times. An aircraft will deviate from its planned departure time and flight path to “harvest” prime sections of the atmosphere. Consequently, just as passengers have the option to lower their ticket prices by choosing inconvenient departure times and longer indirect flights, adoption of the method by the airline industry will enable passengers to trade these same options for a lower “environmental price”. The method enables the airline industry to switch from a contributor to global warming, to a contributor to global cooling. In this respect, the method enables the airline industry to be a global cooling technology comparable to carbon capture and sequestration. Unlike the immense capital investment required by other global cooling technologies, the method requires no capital investment because it exploits the existing multitrillion-dollar global air transportation infrastructure.
