" The standard modern estimate of climate sensitivity – 3 °C, plus or minus 1.5 °C – originates with a committee on anthropogenic global warming convened in 1979 by the National Academy of Sciences and chaired by Jule Charney. Only two sets of models were available; one, due to Syukuro Manabe, exhibited a climate sensitivity of 2 °C, the other, due to James E. Hansen, exhibited a climate sensitivity of 4 °C. “According to Manabe, Charney chose 0.5 °C as a not-unreasonable margin of error, subtracted it from Manabe’s number, and added it to Hansen’s. Thus was born the 1.5 °C-to-4.5 °C range of likely climate sensitivity that has appeared in every greenhouse assessment since…”[16]
Many people have tried to develop more accurate estimates. The current range is anything from zero to 10°C, though the latter number is usually dismissed. As time goes by, the number seems to be dropping. Recent ice-age studies don’t change the old estimates by very much, but give a median value of 2.3°C. Even more recently, there have been efforts to calculate climate sensitivity from thermodynamic principals. Find the papers here, here, and here. These all suggest that the climate sensitivity is zero. Measurements from above the atmosphere all suggest that climate sensitivity is less than 0.6°C. See here, here, and here."
