Do you have any idea how the IPCC reports are created
In fact, I do know that these scientists you speak of have concluded that none of the studies cited has shown clear evidence that we can attribute the observed climate changes to the specific cause of increases in greenhouse gases; that no study to date has positively attributed all or part of the climate change observed to anthropogenic causes; that claims of positive detection of significant climate change are likely to remain controversial until uncertainties in the total natural variability of the climate system are reduced; that while none of these studies has specifically considered the attribution issue, they often draw some attribution conclusions for which there is little justification; that any claims of positive detection of significant climate change are likely to remain controversial until uncertainties in the total natural variability of the climate system are reduced; and that they do not know when an anthropogenic effect on climate change will be identified.
The IPCC did not want any of these things said. It asked a single scientist, Dr. Ben Santer of the Lawrence Livermore National Laboratory, to rewrite the already-concluded
final draft to remove all five statements shown above, and to replace them with:
"The body of evidence now points to a discernible human influence on global climate."
Willful data manipulation:
The IPCC decided in its 2001 report to depart from its 1990 First Assessment Report, which had shown a schematic indicating that the mediaeval warm period had been appreciably warmer than the present.
However, 11 years later, in the 2001 Third Assessment Report, the mediaeval warm period had been made to disappear.
In 1995, Dr. David Deming had written a paper in Science on the reconstruction of pre-instrumental surface temperatures by borehole measurements. As a result, he was congratulated by several scientists. In 2005 he wrote:
“A major person working in the area of climate change and global warming sent me an astonishing email that said, ‘We have to get rid of the Mediaeval Warm Period
