New Climate Data Rigging Scandal Rocks US Government
But what does it matter anyway?
New Climate Data Rigging Scandal Rocks US Government
But what does it matter anyway?
It's not the first time data has been manipulated.

Here's the bottom line. A survey of 82% of USHCN surface temperature stations found that 89% of these stations did not meet CRN criteria for accuracy. The discrepancy was 0.7C degrees over the past century. Pictures of about 100 of these unreliable stations are included in the above linked PDF file.
Worse, see Figures 22, 23, and 24 in the above link. The raw data was then further "adjusted" to show lower temps from 1900 to 1940, a big jump up in the 1950s, and about the same as actual measurements from then on.
This adjustment hides the big decline in temp from 1940 to 1970, which cannot be explained by current computer models
Further, this chart (
http://www.drroyspencer.com/global-warming-background-articles/2000-years-of-global-temperatures/
) shows that there have been four centuries over the past 2,000 years when temperatures climbed as fast as they have in the last half of the 20th century.
This chart stops at 1950, but adding warming since then puts global temps about the same as during the Medieval Warming Period... when CO2 levels were far lower.
