In 1951, MIT professor Hurd C. Willett predicted 20 years of global cooling, based on sunspot cycles.

The cooling occurred exactly as he predicted. Scientists blamed all bad weather on global cooling, and other scientists discovered a relationship between sunspots and winter storms. Dr. Walter Orr Roberts at NCAR said their discovery was “of overwhelming importance.”

The cooling has since been erased by NASA, as has Walter Orr Roberts legacy as a solar physicist. NCAR now describes him as an early climate change advocate.
NASA has erased the post-1940’s global cooling.
