1977
Scientific opinion tends to converge on global warming, not cooling, as the chief climate risk in next century. =>Public opinion1978
Attempts to coordinate climate research in US end with an inadequate National Climate Program Act, accompanied by rapid but temporary growth in funding. =>Government1979
Second oil "energy crisis." Strengthened environmental movement encourages renewable energy sources, inhibits nuclear energy growth. =>Public opinionUS National Academy of Sciences report finds it highly credible that doubling CO2 will bring 1.5-4.5°C global warming. =>Models (GCMs)
World Climate Research Programme launched to coordinate international research. =>International
1981
Election of Reagan brings backlash against environmental movement to power. Political conservatism is linked to skepticism about global warming. =>GovernmentIBM Personal Computer introduced. Advanced economies are increasingly delinked from energy.
Hansen and others show that sulfate aerosols can significantly cool the climate, raising confidence in models showing future greenhouse warming. =>Aerosols
Some scientists predict greenhouse warming "signal" should be visible by about the year 2000. =>Modern temp's
