Liar, Liar, Pants on Fire or Where Global Warming is Really Coming From

From Life Extension News
According to a report in Environment & Climate News,(1) James Hansen, astronomer and director of NASA’s Goddard Institute for Space Studies (GISS) has been caught doctoring temperature data from California “to make a long-term cooling trend look like a warming trend.” The article explains that the temperature history (as reported by the U.S. Historical Climatology Network (USHCN) for Santa Rosa, California) was examined by California meteorologist Anthony Watts and found to show a long-term decline, especially since the 1930’s. Watts then examined the temperature history for the same town as reported by GISS; the GISS report was completely different, reporting a long-term increase in Santa Rosa temperature. “USHCN reports a decline of nearly one-half degree Celsius during the twentieth century, while GISS reports a temperature increase of one-half a degree.”(1)

The article goes on to explain that the USHCN measures temperature by “taking daily readings from an immobile temperature station,” while GISS collects the USHCN temperature readings and then subjects them to adjustments (using methods which Hansen will not reveal), allegedly to correct for artificial influences such as land-use changes. The urban heat island effect (as Santa Rosa’s population increased from slightly more than 10,000 in 1905 to about 158,000 today) would have been expected to result in warmer temperatures (unrelated to global influences) and, hence, to adjust for the urban heat island effect would require the long-term temperature record should be adjusted downward, not upward. Yet, GISS is adjusting the raw temperature data upward instead of downward.

In the article on the facing page,(2) it described how “[i]n 2007, statistical scientists showed GISS had been artificially inflating U.S. temperatures by 0.15 degrees Celsius since the year 2000.” Furthermore, “[i]n 2008 statistical scientists showed GISS had falsely reported October 2008 was the warmest October on record when, in fact, it was a quite normal temperature month.” NASA later admitted that the “Warmest October” claim had been wrong.(3)
