HadCRUT Data Manipulation Disappears Inconvenient 2000-2014 Warming Pause

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.
