Disclosure of Climate Data - Submission to UK Parliament

Technical Rating: star
Steve McIntyre prepared this submission to the UK Parliamentary Committee investigating the Climategate scandal. The Climate Research Unit "has manipulated and/or withheld data with an effect on the research record. The manipulation includes (but is not limited to) arbitrary adjustment ("bodging"), cherry picking and deletion of adverse data."

Surface Temperature Record: Policy Driven Deception?

Technical Rating: star
Instrumental temperature databases exhibit very serious problems that render them useless for determining accurate long-term temperature trends. This report shows that contamination by urbanization, changes in land use, improper siting and a reduction of reporting stations have caused a severe warming bias.

Are We Feeling Warmer Yet?

Technical Rating: star
This paper compares the raw and adjusted temperature trends in New Zealand. The official adjusted temperature trend is 0.92 C/century. The raw data temperature trend is 0.06 C/century. The adjustments increased the trend fifteen-fold. There is nothing in the station histories to warrant these adjustments.

The Dog Ate Global Warming

Technical Rating: star
In the National Review Dr. Pat Michaels recounts the manipulations by UK's Climate Research Unit to keep the basic worldwide temperature data out of the hands of researchers that may want to question some of their methodology. Many adjustments were made to the original temperature data, which the CRU claims has been lost or destroyed.

The Yamal Implosion

Technical Rating: star star
Mr. Steve McIntyre of Climate Audit has discovered that the Yamal tree ring series used a small subset of the available data. Tree ring data is used to estimate historical temperatures. The Yamal series, which is used in multiple studies, show a hockey stick shape with rapid warming in the 20th century. When all the relevant data is used the hockey stick disappears and the medieval era is warmer than the current period. Bishop Hill has prepared this layman's narrative.
