1951 : MIT Scientist Predicted Global Cooling Based On Sunspots

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.

    ….and when the cold cycle ended
    they called this natural warming global warming caused by co2 instead of sunspots.

    And the left side of the global cooling Des Moines article
    is the blueprint that is used nowadays to promote global warming.It’all there,
    the catastrophies,
    the mounting evidence.

    This is not criminal?

    I followed the predictions of Dr. Willett over my lifetime and he was amazingly accurate. He predicted the 1955-1979 cooling, including the very severe consecutive winters of 1977, 1978 and 1979. He amazingly stated beforehand that the late 1970’s would be a period of “climate stress”. He also predicted the rebound in temperatures that took place during the late 20th Century.

    Nowhere in his predictions did Dr. Willett even mention CO2.

    • Ross says:

      So I presume Dr Willett would have predicted the current cooling based on reduced sun spot numbers.
      What is the old saying? ” If you do not learn from history you …..

    Agricultural commodity speculators noticed that correlation about a century ago.

    Henrik Svensmark has validated that correlation by explaining that sunspot activity reflects increased solar radiation. Increased solar radiation “protects” the earth somewhat by blocking some of the ongoing cosmic ray activity in the lower atmosphere. CERN has verified that an increase in cosmic ray activity causes more cloud formation.

    There is probably still a youtube showing Svensmark giving a seminar on this theory (back in the 90s as I recall). Most of the folks attending that seminar looked as if they were attending their closest friend’s funeral.

    This was speculators in England.

  6. Acording to old studies (1934-35) about locust invasions in NW India by Ramchandra Rao, there is a clear correlation between sunspots number and locust invasions. The same thing has been observed back in the 1940s in Argentina. I have a PDF copy of those studies in Argentina… Below is a graph about this matter.
