Why Scientists are ‘Sceptical’ About the AGW Concept

Abstract: The strong climate-forcing effect of rising atmospheric CO2 concentrations advocated by the IPCC, is at odds with climate developments during geological, historical and recent times. Although atmospheric CO2 concentrations continuously increased during industrial times, temperatures did not increase continuously to the present level but stagnated or even declined slightly during 1880 to 1900, 1945 to 1977 and again since 1998. Total solar irradiation rose from a low in 1890 to a first peak in 1950 that was followed by a sharp decline ending in 1977, giving way to a period of rapidly increasing radiation peaking in 2002 when solar activity started to decrease, possibly declining to a new Little-Ice-Age type low. The Greenhouse Effect of increasing atmospheric CO2 concentrations, claimed and widely propagated by IPCC, is particularly vexing as it is widely over-estimated without adequate scientific justification. Large observed climate variations documented for geological and historical times, as well as the lack of insight into the behaviour of complex systems, seriously question the Anthropogenic Global Warming (AGW) concept propagated by the IPCC. The climate variability during industrial times was essentially governed by changes in solar activity with increasing atmospheric CO2 content playing a subordinate role. The climate controlling effect attributed by the IPCC to increasing atmospheric CO2 concentrations is rejected since supporting models are not compatible with observations. Lastly, the authors consider from a historical and philosophical science point of view why current mainstream climate change research and IPCC assessments may have been on an erring way for several decades.
THE GRAPHS TELL THE TRUTH. THE GRAPHS ARE FROM THE NOAA, AND OFFICIAL SCIENTIFIC FEDERAL AGENCY. 91% OF THE WORLD'S ICE IS ON ARTARCTICA, AND IT STILL ACCRETING, ERGO NO RISE IN SEA LEVELS. THERE ARE NO PEER REVIEWED ARTICLES SHOWING PROOF OF ANTHROPGENIC GLOBAL WARMING; ONLY CONJECTURE.ReplyDelete
