Something happened to the climate around 1950 causing sharp cooling. This was reported by NOAA and many other “specialists”
The current crop of NOAA criminals have since erased most of the Northern Hemisphere cooling, and created fake southern hemisphere trends from inadequate data.
One place where this cooling was particularly evident was in Georgia, where many stations reported a huge decline in temperatures after 1950.
If climate scientists were actual scientists, they would try to understand the climate rather than alter the data to fit their failed theory.
