The amplitude of the recorded warmth in the 1940s was always a problem for purveyors of the human-caused global warming narrative. [emphasis, links added]
So the 1940s temperatures have been artificially cooled to make this less of a problem.
In 2009, overseers of the HadCRUT global temperature data discussed “correcting” the “1940s warming blip” in e-mails that they later tried to hide from Freedom Of Information Act (FOIA) investigators.
“So, if we could reduce the ocean blip by, say, 0.15 deg C, then this would be significant for the global mean — but we’d still have to explain the land blip.”
“I’ve chosen 0.15 here deliberately.”
“It would be good to remove at least part of the 1940s blip, but we are still left with ‘why the blip?’.”
And, like they had said they would, 0.15°C of warmth has gradually been removed from the 1940s HadCRUT global temperature data over the last 15 years.
They have “corrected” the data to align with their narrative.
What’s also noticeable here in this HadCRUT-changes-temperature-data chart provided by climate4you is just how much warmth has been added to 21st-century temperatures since 2008.
The HadCRUT3 global temperature trend was recorded as 0.03°C per decade during the global warming hiatus years of 2000-2014 (Scafetta, 2022).
This was increased to 0.08°C per decade by version 4, as the overseers of the HadCRUT data conveniently added 0.1°C to 0.2°C to the more recent anomalies.
Today, in HadCRUT5, the 2000-2014 temperature trend has been adjusted up to 0.14°C per decade when using the computer model-infilling method.
So, within the last decade, a 15-year temperature trend has been changed from a pause to a strong warming.
After all, when the observations don’t fit the narrative, it is time to change the observations.
