Adjustments add significant warming to 21st-century temperature trends.
From 2009 to 2019, there were 90 peer-reviewed scientific papers published on the global warming “pause” or “hiatus” observed over the first 15 years of the 21st century.
The HadCRUT3 global temperature trend was recorded as 0.03°C per decade during the global warming hiatus years of 2000-2014 (Scafetta, 2022). [emphasis, links added]
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 strong warming.
After all, when the data don’t fit the narrative, it is time to change the data.

Once data are “adjusted” they cease to be data. In this case, they become what the manipulators realize they needed to be to support the narrative.
Hadley Center is hardly the only guilty party.
