Temperature data tampering adds 2 degrees warming

Real Climate Science | 20 March 2018

NOAA’s US temperature record shows that US was warmest in the 1930’s and has generally cooled as CO2 has increased.  This wrecks greenhouse gas theory, so they “adjust” the data to make it look like the US is warming.

Raw NOAA Data      Adjusted NOAA Data

The NOAA data tampering produces a spectacular hockey stick of scientific fraud, which becomes the basis of vast amounts of downstream junk climate science. Pre-2000 temperatures are progressively cooled, and post-2000 temperatures are warmed. This year has been a particularly spectacular episode of data tampering by NOAA, as they introduce nearly 2.5 degrees of fake warming since 1895.

Most of these adjustments are due to simply making up data.  Every month, a certain percentage of the 1,218 United States Historical Climatology Network (USHCN) stations fail to report their data, and the temperature gets estimated by NOAA using a computer model. Missing data is marked in the USHCN database with an “E” – meaning “estimated.” In 1970, about 10% of the data was missing, but that number has increased to almost 50%, meaning that almost half of the current adjusted data is fake.

The fabricated temperatures have warmed four degrees since 1970, relative to the adjusted temperatures which were based on actual station data. This shows that the warming trend in the US claimed by NOAA is based on computer models, not actual thermometer data or even adjusted thermometer data.

But here is the real smoking gun of fraud by NOAA. The adjustments being made almost perfectly match atmospheric CO2 levels – showing that the data is being altered precisely to match global warming theory.

Science doesn’t get any worse than how NOAA handles US temperature data. NASA uses the NOAA data as the basis for their temperature graphs, which have also been massively altered to turn cooling into warming.
