Hoaxes: Climate researchers and the Weather Channel's founder accuse NASA of the same data manipulation as Britain's Climate Research Unit. Were weather stations cherry-picked to hide the temperature drop?
We recently commented on how our space agency for two years refused Freedom of Information requests on why it has had to repeatedly correct its climate figures.
In a report on global warming on KUSI television by Weather Channel founder and iconic TV weatherman John Coleman, that reticence has been traced to the deliberate manipulation and distortion of climate data by NASA.
As Coleman noted in a KUSI press release, NASA's two primary climate centers, the National Climatic Data Center (NCDC) in Asheville, N.C., and the Goddard Institute for Space Studies at Columbia University in New York City, are accused of "creating a strong bias toward warmer temperatures through a system that dramatically trimmed the number and cherry-picked the locations of weather observation stations they use to produce the data set on which temperature record reports are based."

NASA GISS Temperature Records Altered - Why?
On January 26, 2012, a short report written by Steven Goddard dealing with the modification of temperature records was published in the German version at EIKE’s internet portal. By using the examples of Reykjavik (Iceland), Godthab Nuuk (Greenland) and all stations of the US, it was demonstrated that temperature curves were altered to produce the impression that the Arctic has been warming up since 1920.
The temperature records are made up of the monthly and yearly averages and the corresponding temperature curves. The temperature curves depict the temperature variations over time. The inclination of the trend line tells us whether the average temperature is flat, increasing, or decreasing. An inclined trend line yields a gradient given in °C/year, i.e. the yearly rate of temperature change.
Examples: Reykjavik and Godthab Nuuk
Fig. 1 compares the original temperature curves of the stations Reykjavik and Godthab Nuuk (left) from the year 2010 with those altered by NASA GISS in 2012 (right).
These newly altered Arctic region temperature records lead the observer to believe that the Arctic apparently became progressively warmer. However, this kind of alteration was not only applied to the Arctic. Steven Goddard also considered the overall temperature curve USHCN Version 1 of all 1221 stations in the USA introduced in 1990, published by James Hansen in 1999 as “USHCN v.1”, see Fig. 2
In Fig. 2 the left temperature curve very clearly shows the first warming phase of 1920 to 1940, which was then followed by cooling until, 1980 and then by the second warming period from 1980 to 1995. The first warming was stronger. The overall trend line shows a moderate inclination, indicating a rather small yearly warming.
The right temperature curve in Fig. 2 shows the opposite: the values of the first warming were lowered while those of the second one were adjusted upwards. The scale of the y-axis was modified as well, altogether producing a steeper overall trend line, i.e. a stronger warming. That alteration gives the appearance of a distinct warming for the entire USA. This same data is available for over 100 national reporting stations.
This is the greatest fraud in history!
