I have spend decades working on weather and climate attribution. We have with the data available been able to see cycles in the weather and global climate related to the sun and cycles in the ocean (likely related to the sun, our biggest source of energy for the atmospheric and oceanic systems). But since the 1960’s, most of the thinking increasingly was related to man’s activity, blaming cooling on the ‘human volcano’ (aerosols from burning of fuels) and warming on greenhouse gases.

Back in the early 1970s, CBS anchor Walter Cronkite, the dean of American journalism, was warning about an “ice age.” Cronkite cited scientific claims that the Earth was cooling and “the full extent of the new ice age won’t be reached for 10,000 years.” (Climate Depot)

On September 11, 1972, Cronkite cited scientists’ predictions that there was a “new ice age” coming. He called that prediction from British scientist Hubert Lamb “a bit of bad news.”

“But then there is some good news,” Cronkite continued. “That while the weather may be just a little colder in the immediate years to come, the full extent of the new ice age won’t be reached for 10,000 years. And if you can stand any more good news, even then it won’t be as bad as the last ice age 60,000 years ago. Then New York, Cincinnati, St. Louis, were under 5,000 feet of ice. Presumably no traffic moved and school was let out for the day. And that’s the way it is, Monday, September 11, 1972.”

Lamb, the scientist Cronkite cited, was no fringe scientist. He founded the Climatic Research Unit at the University of East Anglia in Great Britain. When he died, the CRU director called him “the greatest climatologist of his time,” according to the Global Warming Policy Foundation. He was also credited with establishing “climate change as a serious research subject.”

The late Cronkite is considered a “legendary journalist” and a pioneer in the field, which is why Marc Morano, publisher of Climate Depot, said this footage was so important. Morano is a former staff member of U.S. Senate Environment & Public Works Committee and producer of the upcoming global warming documentary Climate Hustle, released in 2015.

“Global warming activists have claimed for years that the 1970s global cooling scare never existed. They have tried to erase the inconvenient history which ironically blamed extreme weather like tornadoes, droughts, record cold and blizzards on global cooling,” said Morano.

Leonard Nimoy famous as Mr. Spock on Star Trek provided more detail on the thinking of the world’s best scientists at the time in a teaser overview and then a longer detailed story.

Unlike scientists often quoted by the media today, GWPF said that Lamb viewed the Earth’s climate as changing constantly and naturally. Unlike its founder, CRU now has a major role in spreading global warming alarmism. CBS said in 2009, CRU “wields outsize influence” in warming circles. The Climategate scandal centered around leaked documents and emails from that organization.

“Climate fear promoters switched effortlessly from global cooling fears in the 1970s to global warming fears in the 1980s. In the present day, the phrase ‘global warming’ has lost favor in favor of ‘climate change’ or ‘global climate disruption’ or even ‘global weirding,’ Morano added. “‘Settled science’ has never seemed so unsettled.”

Watch: Flashback 1980 CBS News w/ Walter Cronkite warns of ‘greenhouse effect’ causing ‘disruptive changes’ in ‘50-70 years’ - Cites ‘16 degrees F’ warming & ‘goodbye Miami’ & ‘boating at foot of Capitol’.
.
CBS News: “Researchers say increasingly large amounts of CO2 are accumulating in the atmosphere. They fear the earth will gradually become warmer causing as yet uncertain but possibly disruptive changes in the Earth’s climate 50 to 70 years from now.” ...

Sen. Paul Tsongas (D-Mass) Senate Energy Committee: “It’s possible probable we really don’t know. But if it happens it means goodbye Miami, goodbye Corpus Christi, goodbye Sacramento, goodbye Boston—which obviously is much more of a concern. Goodbye New Orleans. Goodbye Charleston, Savannah, and Norfolk. On the positive side, it means that we could enjoy boating at the foot of the Capitol and fishing on the South Lawn.”

Gordon MacDonald, Mitre Corp Chief Scientist: “One model of climate the Jason climate model predicts that doubling carbon dioxide will result in August and Washington DC that are 9 degrees centigrade warmer or 16 degrees Fahrenheit than current summers but that the winters will only be 2 degrees centigrade warmer changes of this. Changes of this magnitude are very probably going to have a profound effect on agriculture, on all of the aspects of energy use and generation, and on water and land use.”
