Manabe, S., and R. J. Stouffer, 1979: A CO2-climate sensitivity study with a mathematical model of the global climate. Nature, 282 (5738), 491-493.
Abstract: An increase in the CO2-content of the atmosphere resulting from man's activity could have a significant effect on the climate in the near future. We describe here some new results from a study of the response of a mathematical model of the climate to an increase in the CO2-content of the air.
