They erased the ”very extraordinary period of warmth” of the 1930s.
We know that polar ice and alpine glaciers melted rapidly between 1910 and 1950. We know that the 1930s were very hot. We know that the 1970s were cold, and ice was expanding.
Yet Hansen and Jones both show the 1970s much too warm, and the 1930s much too cold.
Here is another critical piece of evidence. In 1975, Science News published the graph below of northern hemisphere temperatures, from the National Academy of Sciences.
Since 1940, the temperature of the Northern Hemisphere has been steadily falling: Having risen about 1.1 degrees C. between 1885 and 1940, according to one estimation, the temperature has already fallen back some 0.6 degrees, and shows no signs of reversal
To gain a perspective on these divergent views, SCIENCE NEWS interviewed C. C. Wallen, chief of the Special Environmental Applications Division, World Meteorological Organization, at the wmo headquarters in Geneva. The cooling trend observed since 1940 is real enough, he says, but not enough is known about the underlying causes to justify any sort of extrapolation. Particularly dangerous would be any attempt to generalize from even shorter-term experience, like the bad weather in 1972 and following years, to prognosticate any future weather patterns. On the other hand, the cooling since 1940 has been large enough and consistent enough that it will not soon be reversed, and we are unlikely to quickly regain the “very extraordinary period of warmth” that preceded it. Even this mild diagnosis can have ”fantastic implications” for present-day humanity, Wallen says.
Now look at the composite. Hansen whacked a huge chunk off all temperatures prior to the 1950s. (This graph was corrected from the original published, which had a shift error.)
This is very similar to what Hansen did to the US temperature record. The whole global warming story falls apart without this blatant data tampering.
Hansen continues to tamper with the data set, and Jones is about to do his biggest tampering to date with HadCRUT v4.

This is great stuff Steve! Nice detective work.
dang…where are you finding all this stuff
Great Job! again
Thanks. This document has been around for a long time, but the pieces are starting to fit together.
yes, but Steve Mosher says all is good and GISS is old hat.
Great work dude….it basically shows very clearly the ‘adjustments’ being made to show warming trend when basically it was just cyclical…
WOW Hansen has it completely backwards. Remember when NASA was pretty damn awesome?
Yeh, back when they concerned themselves with space and real science.
lol, so what was the base atmospheric CO2 level? From the “climate change chilling possibilities” paper…….
“According to the academy report, atmospheric carbon dioxide has been rising
by four percent a year since 1910, because of industrialization. Stephen H.
Schneider of the National Center …… “
Oops… someone is FOS again.
Dear James Hansen,
Please note the following -
Real science publishes archives, making them available through a public forum. These forums would normally have access to all the raw input data of papers along with all computer scripts and codes used to generate any output.
The standard for reputable scientific publication is to have peer reviewers. These people are given complete access to all data so they can dispassionately review, audit, and look for errors, omissions, and problems. Reputable publications never have reviewers that are coworkers or associates of the authors.
Normally reputable science proceeds with disclosure and due diligence, and it is common sense to disregard any papers that have closed data and methods that can not be independently verified. Obviously the greater the impact of the research has on humankind the greater the level of scrutiny is required.
Real science is humble. Many things are unknown, some unknowable. It is a human tendency to deny the idea that some features of our universe are beyond the reach of our knowing at this time, no matter how much money we pour into researching it.
Despite all the shroud-waving over the years, humans have not managed to break nature. It is crass arrogance to think we can.
Thank-you but no thank-you for your input on this matter.

I saw this on the tips at WUWT, looking like another cooling the past in Australia – Alice springs with some -2.1°:
