The Earth’s feedback response to warming is independent of the nature of the forcing that caused that warming. The question I intend to examine is whether the nature of the forcing will have a significant impact on the initial warming or the response time of the earth’s system. I looked at changes in three different types of forcing and their effect on the earth’s temperature response.
1. Changes in solar forcing caused by variation in solar output at the sun’s surface that may cause changes in Cosmic Ray flux or other solar multiplier effects.
2. Changes in solar forcing caused by changes in the earth’s milankovitch cycles (Last Glacial Maxima, LGM) and volcanic activity that do not affect cosmic ray flux.
3. Changes in Anthropogenic Green House Gas (AGHG) concentrations.
The IPCC and others assume that climate sensitivity derived from #2 (Last Glacial Maxima…
