Once Again: Global Warming Data “Adjusted” to Show Warming Trend

This comes as no surprise to us that global warming data have been adjusted significantly to yield the desired result of creating a global warming panic. The only thing that’s manmade about global warming is the “theory” itself. The Telegraph reported:

Two weeks ago, under the headline “How we are being tricked by flawed data on global warming,” I wrote about Paul Homewood, who, on his Notalotofpeopleknowthat blog, had checked the published temperature graphs for three weather stations in Paraguay against the temperatures that had originally been recorded. In each instance, the actual trend of 60 years of data had been dramatically reversed, so that a cooling trend was changed to one that showed a marked warming.

This was only the latest of many examples of a practice long recognized by expert observers around the world – one that raises an ever larger question mark over the entire official surface-temperature record.

Following my last article, Homewood checked a swathe of other South American weather stations around the original three. In each case he found the same suspicious one-way “adjustments.” First these were made by the US government’s Global Historical Climate Network (GHCN). They were then amplified by two of the main official surface records, the Goddard Institute for Space Studies (Giss) and the National Climate Data Center (NCDC), which use the warming trends to estimate temperatures across the vast regions of the Earth where no measurements are taken. Yet these are the very records on which scientists and politicians rely for their belief in “global warming.”

Homewood has now turned his attention to the weather stations across much of the Arctic, between Canada (51 degrees W) and the heart of Siberia (87 degrees E). Again, in nearly every case, the same one-way adjustments have been made, to show warming up to 1 degree C or more higher than was indicated by the data that was actually recorded. This has surprised no one more than Traust Jonsson, who was long in charge of climate research for the Iceland met office (and with whom Homewood has been in touch). Jonsson was amazed to see how the new version completely “disappears” Iceland’s “sea ice years” around 1970, when a period of extreme cooling almost devastated his country’s economy.

One of the first examples of these “adjustments” was exposed in 2007 by the statistician Steve McIntyre, when he discovered a paper published in 1987 by James Hansen, the scientist (later turned fanatical climate activist) who for many years ran Giss. Hansen’s original graph showed temperatures in the Arctic as having been much higher around 1940 than at any time since. But as Homewood reveals in his blog post, “Temperature adjustments transform Arctic history,” Giss has turned this upside down. Arctic temperatures from that time have been lowered so much that that they are now dwarfed by those of the past 20 years.

They were barely able to make the case using their “adjusted” data that last year was the “hottest year on record.” Then after all the headlines had subsided, they said, “Okay, maybe it wasn’t the hottest year.”  

Not only are the data adjusted, the surface temperature stations are located in very biased areas to begin with. Most of them are positioned on asphalt parking lots or in close proximity to an artificial heat-generating source like an air conditioning unit, a city building, or a transformer, in violation of the National Weather Service’s own rules on surface station siting. Those stations are obviously going to produce an artificially hot reading.

These people have already decided that manmade global warming is real. Or at least they’re paid to say that it’s real. As government-funded “scientists,” they’re tasked with making sure the data come to the “appropriate” conclusion.
