Comment: Evaluation of the Homogenization Adjustments Applied to European Temperature Records in the Global Historical Climatology Network Dataset

As they say: Garbage in, garbage out! Climate data is massaged in sometimes dubious ways or even manipulated (e.g. by excluding weather station data that contradict the narrative of Global Warming)

Climate models are a hoax: We cannot even forecast weather fairly accurate for more than a few days (Make no mistake weather is as complex climate). They cannot backcast!

From the abstract:

"... However, only 19% of the breakpoints (18% for Version 3) were associated with a documented event within 1 year, and 67% (69% for Version 3) were not associated with any documented event. Therefore, while the PHA remains a useful tool in the community’s homogenization toolbox, many of the PHA adjustments applied to the homogenized GHCN dataset may have been spurious ..."
