Global Warming: Beyond the Tipping Point
Terms and Allusions
It refers to the standard modern estimate of climate sensitivity for how much the global mean temperature will rise if atmospheric CO2 is doubled from its preindustrial levels, before people began burning coal and oil on a grand scale. In the mid-1800s carbon dioxide concentrations stood at about 280 ppm. If it is doubled to 560 ppm, the Charney sensitivity calculation estimates that temperatures should rise about three degrees C. Charney Sensitivity originated with a committee on anthropogenic global warming convened in 1979 by the National Academy of Sciences and chaired by Jule Charney. However, this calculation is wrong because it assumes that the land surface, ice sheets and atmospheric composition stay the same.
