IPCC and the Dunde Variations

Here.

Excerpt:

There’s not much in climate science that annoys me more than the sniveling acquiescence of government bureaucrats in Lonnie Thompson’s flouting of data archiving policies. To his credit, Thompson has collected unique data. To his shame, Thompson has failed to archive data collected as long as 20 years ago. This would be bad enough if the versions were consistent in all publications on Dunde. But Thompson seems to have tinkered with his results over the years so that there has been an accumulation of inconsistent versions, compromising any ability to properly use this unique data. Needless to say, mere compromising of the data hasn’t stopped climate “scientists” from using Thompson data.
