Hansen et al. (1981), «emerge» p. 957; another scientist who compared temperature trends with a combination of CO2, emissions from volcanic eruptions, and supposed solar cycles, likewise got a good match, and used the cycles to predict that greenhouse warming would swamp other influences after about 2000.
