From No Tricks Zone:

 

Veteran journalist Günter Ederer* writes a piece reporting that massive alterations have been found in the NASA GISS temperature data series, citing a comprehensive analysis conducted by a leading German scientist. These results are now available to the public.

Ederer reports not long ago retired geologist and data computation expert Professor Dr. Friedrich Karl Ewert began looking at the data behind the global warming claims, and especially the datasets of NASA’s Goddard Institute of Space Studies (GISS).

Ewert painstakingly examined and tabulated the reams of archived data from 1153 stations that go back to 1881 which NASA has publicly available – data that the UN IPCC uses on which to base its conclusion that man is heating the Earth’s atmosphere through the burning of fossil fuels. According to Ederer, what Professor Ewert found was “unbelievable”:

From the publicly available data, Ewert made an unbelievable discovery: Between the years 2010 and 2012 the data measured since 1881 were altered so that they showed a significant warming, especially after 1950. […] A comparison of the data from 2010 with the data of 2012 shows that NASA-GISS had altered its own datasets so that especially after WWII a clear warming appears – although it never existed.”

Ederer writes that Ewert particularly found alterations at stations in the Arctic. Professor Ewert randomly selected 120 stations from all over the world and compared the 2010 archived data to the 2012 data and found that they had been tampered to produce warming.

The old data showed regular cycles of warming and cooling over the period, even as atmospheric CO2 concentration rose from 0.03% to 0.04%. According to the original NASA datasets, Ederer writes, the mean global temperature cooled from 13.8°C in 1881 to 12.9°C in 1895. Then it rose to 14.3°C by 1905 and fell back under 12.9°C by 1920, rose to 13.9°C by 1930, fell to 13° by 1975 before rising to 14°C by 2000. By 2010 the temperature fell back to 13.2°C.

But then came the “massive” altering of data, which also altered the entire overall trend for the period. According to journalist Ederer, Ewert uncovered 10 different methods NASA used to alter the data. The 6 most often used methods were:

• Reducing the annual mean in the early phase.
• Reducing the high values in the first warming phase.
• Increasing individual values during the second warming phase.
• Suppression of the second cooling phase starting in 1995.
• Shortening the early decades of the datasets.
• With the long-term datasets, even the first century was shortened.

The methods were employed for stations such as Darwin, Australia and Palma de Mallorca, for example, where cooling trends were suddenly transformed into warming.

 

The full story is here.

 

It is particularly gratifying to see Prof Ewert’s confirmation of the massive tampering with Arctic temperatures, which I highlighted earlier in the year (and which NOAA/GHCN have STILL failed to give me any explanation for, despite many promises to do so).

 

It should also be noted that his analysis only runs to 2012, so does not pick up on the recent “Pausebuster” scandal now being investigated by the US Congress.

 

 

 

FOOTNOTE

It should be pointed out that Prof Ewert is actually referring to the GHCN V2 raw data, used by GISS prior to 2012, compared against the GHCN V3 Adjusted data used since. Hence the same adjustments made by GHCN are also used by NOAA and HADCRUT.
