Since the 2009 “Climategate” email leak, the UK Met Office has made retrospective adjustments to its climate data going back to the 1930’s as suggested they should in an effort to make the data “align with their narrative.”
According to the Daily Sceptic, the most interesting correction made by the HadCRUT temperature database was a 0.15°C cooling that was inserted into the 1940s in addition to greater warming in recent times.
As part of the leaked emails in 2009, one suggested that there was a “warming blip” in the 1940s and it suggested, “if we could reduce the ocean blip say 0.15°C, then this would be significant for the global mean.” The email noted that it would be beneficial to the data to “remove at least part of the 1940s blip.”
According to the No Tricks Zone (NTZ) blog, the UK Met Office gradually removed the warmth that was seen from the HadCRUT data set, as the leaked email advised.
The outlet also noted that the data had shown just a 0.03°C warming period through 2000-2014, but was then changed to 0.08°C warming per decade in a later version.
“When the observations don’t fit the narrative, it is time to change the observations,” NTZ claimed.
The HadCRUT data set is used by the University of East Anglia Climate Research Unit to improve understanding of why the climate changes and what that could mean in the future. The university was the subject of a data hack in 2009 when thousands of emails from the CRU were leaked to the public, which reportedly showed researchers faked evidence to suggest the planet was rapidly warming to dangerous levels.
The Guardian reported that the contents of the emails were used by people looking to discredit the climate change narrative by undermining the work of the scientists working in the field. One of the scientists named in the leak, Michael Mann, claimed that the emails were "innocent and appropriate conversation between scientists."
