New data on global temperature trends sheds light on the 2009 climate change scandal.
Climategate erupted into public with the release in November 2009 of thousands of emails sent to and from researchers associated with the Climatic Research Unit (CRU) at the University of East Anglia. It became a scandal because some of the emails seemed to suggest that prominent climate researchers may have fiddled with historical climate data with the goal of making recent increases in global average temperature look worse than it is. Suspicion was cast on three sets of historical temperature data, Hadley Centre/CRU series, the NASA Goddard Institute for Space Studies (GISS) series, and a third one from National Oceanic and Atmospheric Administration (NOAA).
As a possible example of scientifically illegitimate manipulation, skeptics pointed to an email from National Center for Atmospheric Research climate scientist Tom Wigley where he mentioned lowering mid-20th century temperatures by 0.15°C. This would have the effect of making the later increase of global temperatures look steeper.
In another email from CRU head Phil Jones reported, Ive just completed Mikes Nature trick of adding in the real temps to each series for the last 20 years (ie from 1981 onwards) amd from 1961 for Keiths to hide the decline. Skeptics decried this trick because it tacked (largely without acknowledging it) thermometer data onto the end of a tree ring data series where the complete set of tree ring data suggested that temperatures had actually declined rather than increased. A graphic using the adjusted data showing a recent sharp increase in northern hemisphere temperatures was published as the cover of the World Meteorological Associations statement [PDF] on the status of the climate in 1999.
Were global warming proponents cherry-picking temperature data to bolster their claims that the world was becoming substantially warmer because...

Hear, hear!!
OK - but regardless I am only a inquisitive old guy
Excellent! Thanks.
Thanks for the link.
