Global Warm-mongering: More Silk from a Pig's Ear

It seems that NASA's James Hansen, head of the Goddard Institute for Space Studies (GISS), is at it again.  He just can't let the data speak for itself.  In yet another egregious display of Anthropogenic Global Warming (AGW) arrogance, he changed the temperature data from 1910-2008 to reflect what is clearly a cooling trend to reflect a warming trend.  (Y-axis = Annual Mean Temperatures in centigrade; X-axis = Year)

These are the USHCN (United States Historical Climatology Network) "raw" and "homogenized" data plots from the GISTEMP (GISS Surface Temperature) website synthesized into one chart with polynomial fit trend lines. As seen in this comparison chart, the Blue Lines represent raw data -- clearly indicating a cooling trend.  Whereas the Red Lines are the adjusted trends after subjected to Hansen's own curiously compensating algorithm.  Junk in = Junk out.

Indeed this past year (2008) is set to be the coolest since 2000, according to a preliminary estimate of global average temperature that is due to be released this month by the Met Office's Hadley Centre in Great Britain. The global average for 2008 should come in close to 14.3C, which is 0.14C below the average temperature for 2001-07.

Nevertheless, global warming partisans at the Met and elsewhere have taken to assuring everyone that cool temperatures are "absolutely not" evidence that global warming is on the wane. Yet those warning and cautionary adamancies are always absent when it comes to linking heat waves to global warming.  "Curiouser and curiouser," said Lewis Carroll.

However, One major glitch in the reporting of temperatures has been quietly forgotten by the Met and others of AGW persuasion as documented here....  When the Soviet Union fell in 1990 the number of reporting weather stations around the world declined from a high of 15,000 in 1970 to 5,000 in 2000, no appropriate compensatory weighting mechanism was thereafter applied.  Such an absence critically skews everything thereafter to the warmer side of things, since it takes some of the coldest places on the planet (like Siberia) out of the equation.  With that absence, it's likely getting colder than we now know.  How convenient! 

Said Geophysicist Dr. David Deming, associate professor of arts and sciences at the University of Oklahoma who has published numerous peer-reviewed research articles:

"Environmental extremists and global warming alarmists are in denial and running for cover.... To the extent global warming was ever valid, it is now officially over. It is time to file this theory in the dustbin of history, next to Aristotelean physics, Neptunism, the geocentric universe, phlogiston, and a plethora of other incorrect scientific theories, all of which had vocal and dogmatic supporters who cited incontrovertible evidence. Weather and climate change are natural processes beyond human control. To argue otherwise is to deny the factual evidence."  

Amen and Amen!
