Exxon’s R.J. Campion memo to J.T. Burgess regarding comments on the American Petroleum Institute’s background paper on CO2 effects. Exxon supports the “API conclusion that no industry research on CO2 (“Greenhouse”) Effects be initiated at this time.” Exxon also wants API’s paper to reflect that the earth is “now in a cooling phase, due to normal cyclic climatic behavior, and will not revert to a warming trend until 1990,” and “It is not likely that any ‘warming’ effects of CO2 will be apparent until at least the year 2000, and probably beyond this time.”
