NASA’s Massive Adjustments:
1910-2000 Now 53% Warmer

In the last 10 years, overseers of the NASA GISS global temperature data set have been busy utilizing cool-the-past-and-warm-the-present adjustment techniques to alter the slope of the overall warming trend.
For example, as the climate4you graph illustrates above, there was a +0.45°C difference between the 1910 temperature anomaly and the 2000 temperature anomaly as of May, 2008.
Today (March, 2018), NASA GISS has tendentiously adjusted up the difference between 1910 and 2000 to +0.69°C, a 53% increase.
The +0.5°C Warming Between 1880-1950 Has Been Erased
Changes to past data consistently serve to cool down the past and warm up the present.
As recently as 1987, for example, NASA GISS reported a warming trend of +0.5°C between 1880 and 1950.
Schneider, S. H. 1989 Science 243: 771-81.
Today, the NASA GISS overseers have removed +0.5°C from 1880 to 1950 trend and replaced it with a 70-year pause. The 2018 NASA GISS graph depicts no change, a 0.0°C non-trend, between 1880 and 1950.

If NASA GISS temperature adjustments can maintain pace with the changes made in the last 10 years, perhaps a decade from now the temperature divergence between 1910 and 2000 will reach a monumental +1.0°C.
Or perhaps NASA GISS will discover there was a cooling trend of -0.3°C between 1880 to 1950 at some point in the next ten years.
We’ll just have to wait and see what temperature data changes NASA GISS will uncover for us next.
