Neat Little 28-page Summary From SEPP

S. Fred Singer
Addressing the Disparity between Climate Models and Observations:
Testing the Hypothesis of Anthropogenic Global Warming (AGW)
Interim Science Update
Presented at Majorana Conference in Erice, Sicily
August 2011

This booklet discusses:
(1) The central issue, the cause of global warming: Is it natural or is it manmade? We update the ongoing controversy. [This issue is of crucial importance for both climate science and for climate policy.]

(2) The chaotic uncertainties of climate models and how to overcome them.

(3) New thinking on Climategate, Hockeystick graph – and what we can say about the absence of post-1979 warming in the temperature data of the 20th century. [Is the reported 1979-1997 warming real?]

(1) We have given here a description of the controversy about the cause of climate change in the 20th century. There is never any question about the observed increases in greenhouse (GH) gases or about their human cause. But we see no evidence at all that any of the temperature changes are human-caused (anthropogenic). We certainly do not see any effect that can be traced to greenhouse gases, such as CO2.

(2) Climate models are known to be chaotic. None of current models have a sufficient number of runs to overcome chaotic uncertainty and therefore cannot be validated against observations.

(3) The global surface warming for 1979 – 1997, reported by CRU-Hadley, NCDC-NOAA, and GISS-NASA, and used by the IPCC to support its claim of a GH-gas cause, is problematic. It is not seen by any other observations; we cite six independent methods, incl. radiosonde, satellite, and proxy data.
