Paper Series on Cosmic Climate Drivers (2)
Jun 25, 2016
In the last decade, GCM climate models of type PMIP2/3 and CMIP3/5 has been developed and widely used in climate science.
In the past years, many of these models were tested by independent model data comparisons showing underperformance in all climate aspects, i.e., in temperature evolution, in global atmospheric circulation and precipitation in the Holocene, and in modeling the last interglacial and aeolian dust. This low model performance over past centennial time frames is a result of insufficient a priori knowledge of the internal workings of the climate system, which is characteristic of complex systems in general and which requires to make often unjustified assumptions about the system. A logical development now is that alternative climate studies increasingly appear.
In a series of eight short papers, Seifert and Lemke introduce and present four major, mostly cosmic climate drivers over the multi-millennial period of the entire Holocene. Using the GISP2 ice-core temperature series (Greenland Ice Sheet Project), each paper describes the specifics of a certain time frame of the Holocene starting from 8500 BC. Two new short papers have been published recently and can be downloaded free.
