Over on WUWT yet another IPCC AR4 gaffe that leaves one with a confirmation of the total and utter unscientific character of the whole IPCC process.
Over the period of 1978 to 2005 the trend in Antarctic ice cover was positive, i.e. the ice mass has been growing consistently over a period of almost thirty year. The trend was 0.7 ± 0.2% per decade. This means that the the ice mass gained 0,7 percent per 10 years, with a margin of error of 0.2%. I.e. the statistically lowest end of the estimated was 0.5%, which is larger then 0, which makes the estimate significant (-ly different from zero).
Yet the IPCC AR4 report has it that
The Antarctic results show a slight but insignificant positive trend of 0.7 ± 0.2% per decade.
(emphasis mine – KV).
Comments by reviewers, all of then honest-to-God scientists, pointing out the error in the statement (calling something insignificant when the estimate is more then tree times as large as the margin of error) were (purposefully?) ignored, even as their comments have been labelled “Taken into account in revised text”.
Can we fire the entire IPCC cabal already?
