Visualizing NOAA/NASA US Data Tampering

In 1991, NOAA showed little or no US warming and correctly showed the 1930s as the hottest decade in the US. They showed the mean US temperature from 1901 to 1990 as 11.4C.

NOAA has since cooled the past and now show the mean US temperature from 1901 to 1990 as 11.1C.

The next graph overlays the 2017 graph on the 1991 graph, at identical scales on both axes. NOAA creates US warming by cooling the past.

NASA does exactly the same thing.  Their 1999 US temperature graph correctly showed the 1930s as the hottest decade in the US, with subsequent cooling through the end of the century.

NASA has since cooled the period 1920-1950 and massively warmed post-1980 temperatures, to turn the cooling trend into a warming trend.

The US is the only place on Earth with reliable long-term temperature data, and both NASA and NOAA have tampered with the data to turn post-1930 US cooling into warming.

But it is much worse than it seems. NOAA has almost no daily temperature data outside of North America prior to 1930, and very little prior to 1950.

In 1974, the National Center for Atmospheric Research showed no net global warming prior to 1970 and a sharp cooling after 1945.

NASA has completely erased the post-1945 cooling and created a large amount of warming prior to 1970.

The US temperature data has been tampered with to turn cooling into warming and the global temperature data prior to 1950 is simply fake. It is time to put this global warming scam down once and for all.

    Back in the 1970’s it was Global Cooling and a New Ice Age and that same liberal leftists rag TIME was putting a Penguin on their front cover of their rag then 20 years later put up a Polar Bear with the Lines BE WORRIED BE VERY VERY WORRIED or showing earth frying like egg in anyway their guilty of lying to their readers as about every other liberal news rag is

    I have said it many times. If the climate change crisis were real, there would be no need to alter the data to support it. The fact that there is so much fraud is one of the strongest statements against AGW.

    What I find most distressing is that President Trump has not put an end to the fraud in NOAA. The people doing it should be fired with cause and in some case prosecuted for committing fraud while on the federal payroll.
