The United Nations Intergovernmental Panel on Climate Change (IPCC) was set up by the United Nations in 1988 and has been trying very hard to demonstrate the threat of a dangerous human influence on climate due to the emission of greenhouse gases. This is in line with their Charter, which directs the IPCC to assemble reports in support of the Global Climate Treaty — the 1992 Framework Convention on Climate Change (FCCC) of Rio de Janeiro.
It is interesting that IPCC “evidence” was based on peer-reviewed publications – but (reluctantly) abandoned only after protracted critiques from outside scientists. E-mails among members of the IPCC team, revealed in the 2009 ‘Climategate’ leak, describe their strenuous efforts to silence such critiques, often using unethical methods.
I will show here that the first three IPCC assessment reports contain erroneous scientific arguments, which have never been retracted or formally corrected, but at least have now been abandoned by the IPCC — while the last two reports, AR4 and AR5, use an argument that seems to be circular and does not support their conclusion. Australian Prof. “Bob” Carter, marine geologist and paleo-climatologist, refers to IPCC as using “hocus-pocus” science. He is a co-author of the latest (2013) NIPCC (Non-governmental International Panel on Climate Change) report “Climate Change Reconsidered-II” http://www.climatechangereconsidereed.org . We also co-authored a critique of the 2013 IPCC-AR5 Summary
1. IPCC-AR1 (1990)
This first report of the IPCC bases its entire claim for AGW on the fact that both CO2 and surface temperatures increased during the 20th century — although not in lock-step. They assign the major warming of 1910 to 1940 to a human influence — based on a peer-reviewed paper by BD Santer and TML Wigley, which uses a very strange statistical argument. But the basis of their statistics has been critiqued (by Tsonis and Swanson) — and I have demonstrated empirically elsewhere that their conclusion does not hold.
While this faulty paper has never been retracted, it is now no longer quoted as evidence by the IPCC — nor accepted by the overwhelming majority of IPCC scientists: Most if not all warming of the early 20th century is due to natural, not human causes.
2. IPCC AR2 (1996)
This report devotes a whole chapter, #8, to “Attribution and Detection.” Its main feature is what one might call the “invention” of the “Hotspot,” i.e. an enhanced warming trend in the tropical troposphere — never actually observed.
Unfortunately, the “evidence,” as presented by BD Santer, was published only after the IPCC report itself appeared; it contains two fundamental errors. The first error was to argue that the Hotspot is a “fingerprint” of human influence — and specifically, related to an increase in greenhouse gases. This is not true. The Hotspot, according to all model calculations, is simply an atmospheric amplification of a surface trend, a consequence of the physics of the tropical atmosphere.
[Technically speaking, it is caused by increased convective activity whereby cumulus clouds carry latent heat from the surface of the tropical ocean into the upper troposphere. In other words, the Hotspot is not human-caused, but arises from a “moist-adiabatic lapse rate” of the atmosphere. This effect is discussed in most meteorological textbooks and is widely accepted.]
How then did AR2 conclude that a Hotspot exists observationally? This is the second issue: The IPCC selected a short interval in the atmospheric temperature record that showed an increase — while the general trend was one of cooling. In other words, they cherry-picked their data to invent a Hotspot
