The WORST Data Set
Berkeley Earth’s US temperature graph shows an impressive hockey stick.
In 1989, NOAA said the US had not warmed over the past century.

In 1999, NASA showed the same thing.

The actual USHCN raw data shows a cyclical pattern with no net warming over the past 80 years.
The graph below overlays The USHCN data and the Berkeley Earth data at the same X-Y scale. Their Y-axis temperatures are ridiculously low, so I normalized the Y-axis to the left side of the graph.
The USHCN raw temperatures closely match the NASA 1999 US temperature graph. But that didn’t fit the global warming agenda, so NASA altered the data.
However, NASA data tampering pales by comparison to the garbage Berkeley Earth is producing,
