In 1974, the National Science Board announced: "During the last 20 to 30 years, world temperature has fallen, irregularly at first but more sharply over the last decade. Judging from the record of the past interglacial ages, the present time of high temperatures should be drawing to an end…leading into the next ice age."
You can't blame these scientists for sucking up to the fed's mantra du jour. Scientists live off grants. Remember how Galileo recanted his preaching about the earth revolving around the sun? He, of course, was about to be barbecued by his leaders. Today's scientists merely lose their cash flow. Threats work.
In 2002 I stood in a room of the Smithsonian. One entire wall charted the cooling of our globe over the last 60 million years. This was no straight line. The curve had two steep dips followed by leveling. There were no significant warming periods. Smithsonian scientists inscribed it across some 20 feet of plaster, with timelines.
So what have they done to airbrush the past?
Last year, I went back. That fresco is painted over. The same curve hides behind smoked glass, shrunk to three feet but showing the same cooling trend. Hey, why should the Smithsonian put its tax-free status at risk? If the politicians decide to whip up public fear in a different direction, get with it, oh ye subsidized servants. Downplay that embarrassing old chart and maybe nobody will notice.
Sorry, I noticed.
Time was when Americans laughed and marvelled at the Soviet press and textbooks as they removed pictures and comments about people who had been "disappeared" by Comrade Stalin. It's not nearly so funny when it's your media, government and scientific community is now engaged in something eerily similar.
The echoes of the past have not been removed, but given time the people who remember and bring these things to light will be tagged as "deniers." So it may be a good time to memorialize a few of these things.
The fall of Saigon in the '70s may have distracted the shrill pronouncements about the imminent ice age. Science's prediction of "A full-blown, 10,000 year ice age," came from its March 1, 1975 issue. The Christian Science Monitor observed that armadillos were retreating south from Nebraska to escape the "global cooling" in its Aug. 27, 1974 issue.
That armadillo caveat seems reminiscent of today's tales of polar bears drowning due to glaciers disappearing.
