THIS WEEK:
By Ken Haapala, President, Science and Environmental Policy Project (SEPP)
Scope: This TWTW will focus on two additional, significant omissions, in the “Summary for Policymakers” of the Physical Science Basis of Sixth Assessment Report (AR6) by the UN’s Intergovernmental Panel on Climate Change (IPCC). The Summary for Policymakers (SPM) is used to justify drastic changes in the use of fossil fuels. Given the magnitude of such changes, the document should be of the highest scientific standards and demonstrate the scientific integrity of the IPCC.
Specifically, a presentation by Stephen McIntyre examining the extent of data, or lack thereof, covering the region of the Southern Hemisphere from 0° to 30° South Latitude will be discussed. Adding this to last week’s presentation covering the region from 30° to 60° South shows that there is very little data supporting IPCC AR6-SPM assertions that temperatures in this major portion of the globe have been roughly stable for the past 2000 years, until humans began emitting CO2 with the beginning of the industrial revolution, roughly 1850.
McIntyre has traced that the assertions that temperatures have been stable up to the industrial revolution come from a set of studies by an international paleoclimatology group based in Bern, Switzerland, known as PAGES 2k (PAst Global ChangES with 2k referring to the past 2000 years). This TWTW looks more deeply into this group and perhaps why it has such influence in the IPCC, particularly in that the work is not peer-reviewed, at least publicly, even though the IPCC claims the work it uses is peer-reviewed and publicly available.
