The body of statistical evidence in chapter 8, when examined in the context of our physical understanding of the climate system, now points to a discernible human influence on the global climate. "( IPCC, Climate Change 1995, Chapter 8, 439)
Santer also deleted these key statements from the expert-approved chapter 8 draft:
"None of the studies cited above has shown clear evidence that we can attribute the observed (climate) changes to the specific cause of increases in greenhouse gases."
"While some of the pattern-base studies discussed here have claimed detection of a significant climate change, no study to date has positively attributed all or part (of the climate change observed) to (man-made) causes. Nor has any study quantified the magnitude of a greenhouse gas effect or aerosol effect in the observed data -- an issue of primary relevance to policy makers."
"Any claims of positive detection and attribution of significant climate change are likely to remain controversial until uncertainties in the total natural variability of the climate system are reduced."
"While none of these studies has specifically considered the attribution issue, they often draw some attribution conclusions, for which there is little justification."
"When will an anthropogenic effect on climate be identified? It is not surprising that the best answer to the question is, "We do not know."
Santer single-handedly reversed the "climate science " of the whole IPCC report -- and with it the global warming political process. The "discernible human influence" supposedly revealed by the IPCC has been cited thousands of times since in media around the world and has been the "stopper" in millions of debates between non-scientists.
The journal Nature mildly chided the IPCC for redoing chapter 8 to "ensure that it conformed" to the report's politically correct Summary for Policy Makers. In an editorial, Nature favoured the Kyoto treaty.
