Thirty Years of Error? In 1988, the Intergovernmental Panel on Climate Change (IPCC) was created by the UN under the World Meteorological Organization (WMO) and the United Nations Environmental Programme (UNEP) from a resolution by the UN General Assembly to address possible future, human-induced, climate change. The reports of the IPCC support the United Nations Framework Convention on Climate Change (UNFCCC). The objective of the UNFCCC is “stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system.” [Boldface added.]
The US Senate ratified the treaty becoming a party of the UNFCCC in 1992.
As readers of TWTW realize, the IPCC estimate future “anthropogenic interference with the climate system,” by using complex mathematical models prepared by others. As discussed in past TWTWs, the mathematical models fail basic testing – they fail to describe what is occurring in the atmosphere with changing greenhouse gases.
More particularly, as discussed in the September 15 and September 22 TWTWs, the publicly archived model runs from the 20 modeling groups participating in the Coupled Model Intercomparison Project Phase 5 (CMIP5) of the IPCC, as a group, greatly overestimate the warming trend occurring in the atmosphere. When specifically tested against the warming of a layer of the tropical troposphere, at 200 to 300 millibar, about 30,000 to 40,000 feet (9100 to 12,200m), they greatly overestimate the warming trends compared with three different datasets from weather balloons taken over the past 60 years. The test can be referred to as the McKitrick- Christy Hypothesis Test.
This failure prompts the question why? Given the extent of modeling expertise, the number of modeling groups involved, and the years of investigation, one must assume that this overestimate is not from a mathematical error in the models. Rather, it may be a systematic error in the thinking that goes into the formulation of these models.
The history of the IPCC by its first chairman, Swedish meteorologist Bert Bolin, gives a clue. Writing a chapter in the Encyclopedia of Life Support Systems after he left the IPCC, he states:
“The realization that human activities might change the global climate was not new. Already at the end of the nineteenth century Svante Arrhenius, professor of chemistry at Stockholm’s Högskola (University), deduced that the global mean temperature might increase by 5°C–6°C if the carbon dioxide concentration in the atmosphere were doubled.”
This claim is not correct. As discussed in last week’s TWTW, in his 1895 paper Arrhenius wrote:
