This is going to be a very difficult task. The LEAKED file,
“HarryReadMe” is believed to have been created by a scientist/ programmer who was attempting to clean up and justify the code. He was completely thwarted in his attempting to do that because so much of what he was seeing was impossibly obtuse, or even CLEARLY was creating biasing errors.
EAU CRU could NOT respond properly to the FOI requests, as a result, without CLEARLY exposing this data manipulation.
ALL of the data from HADCRUT is affected by this.
The ONLY hope of their “new graphs” showing temperature rising in line with the “old” will be IF they can manage to include Urban Heat Island affected stations in such a way that can be unquestioned, and that they will be able to be forgiven about doing that since it “doesn’t matter much” for some reason.
short addendum:
The HarryReadMe file was apparently created itself during a three year effort.
