THE MAIN MISCONCEPTION OF THE GLOBAL WARMERS IS TO ASSUME THAT ALL THE MANY LARGE ENERGY TERMS OF THE CLIMATE SYSTEM REMAIN CONSTANT OVER LONG PERIODS AND THAT THE ONLY CHANGES THAT MATTER FOR CLIMATE ALTERATION ARE THE VERY SMALL MAGNITUDE VARIATIONS OF HUMAN-INDUCED CO2. HOW COULD THE WARMERS BE SO NAÏVE AS TO BELIEVE THAT ONLY CHANGES IN ∆CO2 ARE THE DOMINANT CLIMATE FORCING MECHANISM?

FAMOUS NATIONAL ACADEMY OF SCIENCE (1979) STUDY (The Charney Report)
Doubling CO2 will lead to global ∆T of °C (~3°C) Due to positive water vapor feedback ∆T → ∆ moisture → reduced OLR ∆CO2 RH const.

Heartland 5-12 Chicago A Possible 20th-Century Slowdown of Southern Ocean Deep Water Formation (Wallace S. Broecker, 1 Stewart Sutherland, 1 Tsung-Hung Peng 2) Chlorofluorocarbon-11 inventories for the deep Southern Ocean appear to confirm physical oceanographic and geochemical studies in the Southern Ocean, which suggest that no more than 5 Sv of ventilated deep water is currently being produced... …A major reduction in Southern Ocean deep water production during the 20th century (from high rates during the Little Ice Age) is occurring.
