also Predictions Revisited
Prophet of the Next Ice Age
A hero from the glory days of discovery half a century ago, before the sophistry about man-made global warming invaded climate science, will be speaking at the Fourth International Conference on Climate Change in Chicago, 16-18 May 2010.

In the 1960s a respected geologist in his native Czechoslovakia, George Kukla, counted the layers of loess – windblown mineral dust ground by the glaciers and laid down in the region during recent ice ages. They were separated by darker material left over from warm interglacial periods. Kukla found too many layers of loess. Until then, almost everyone thought that there were just four recent glacial ages, with long interglacials between them. An exception was Cesare Emiliani, who in Chicago in 1955 had traced major variations in heavy oxygen in seabed fossils, and counted seven ice ages. Very few experts believed him until Kukla reported at least nine loess layers in the brickyards of Czechoslovakia.
Following the ill-fated bid for democracy in the “Prague Spring” of 1968 Kukla emerged from behind the Iron Curtain and found refuge at Columbia’s Lamont-Doherty Geological Observatory (now called the Earth Observatory) where he still works.
The observatory perches beside the former glacier valley of the Hudson River. And down at water level Alec Nisbett of BBC-TV filmed Kukla for our multinational TV blockbuster called “The Weather Machine”, broadcast in 1974. By then the count of ice ages had increased still further and the reasons for the comings-and-goings of the ice were better understood. And as you can view here (after a patch of narration read grandly by the actor Eric Porter) Kukla issued a warning. http://www.youtube.com/watch?v=v-Vn5AStFWo
Added 16 May: The wonders of WordPress feedback tell me that only 10% of visitors to this story follow the YouTube link, so I’ll put in the transcript.
Narrator: Will a new ice age claim our lands and bury our northern cities? It’s buried Manhattan Island before, when great glaciers half a mile thick filled the valley of New York’s Hudson River. That’s what an ice age is all about. George Kukla is from Czechoslovakia, where he discovered signs that ice ages are far more frequent that most experts have supposed. Today he continues his work near New York City. For him, the next ice age is not at all remote.
George Kukla: Well almost all of us have been pretty sure that there were only four ice ages, separated by relatively long warm intervals. But now we know that there were twenty in the last two million years. And the warm periods are much shorter than we believed originally. They are something around 10,000 years long. and I’m sorry to say that the one we are living in now has just passed its 10,000 year birthday. That of course means that the ice age is due now any time.
In this post I’ll summarize what was going on in the mid-1970s, about ice age science and climate policy, before catching up with what Kukla thinks nowadays about the coming ice age.

12/06/2010Predictions Revisited and Climate Change: News and Comments
The Wiki Witch of the West
That item quotes my recent Tradecraft of Propaganda post https://calderup.wordpress.com/2010/06/07/tradecraft-of-propaganda/ and also the entry about me in Wikipedia. Added comments defend me from a perceived bias in Wikipedia. But that entry really isn’t too bad, compared with three years ago, when it first picked up on a climate prediction of mine made in 1980.
Here’s the story told in a plain-text email sent in April 2007 to CCNet (Cambridge Conference Network) run by Benny Peiser of Liverpool John Moores University, who’s now director of the Global Warming Policy Foundation.
THE WIKI WITCH OF THE WEST STRIKES AGAIN
Dear Benny
It’s one thing to be held to account for daring predictions made nearly 30 years ago, another to have them perversely rated. Last year a blogger on the Vanity Fair website, Jim Windolf, reported that he had found in a junk shop “a worn-out copy of The Book of Predictions, a compendium of ‘4,000 exclusive predictions’ edited by the family team of David Wallechinsky, Amy Wallace, and Irving Wallace”. Among the gems from 1980 for his readers to chortle about, Windolf picked out the following:
“British science journalist Nigel Calder wrote that, by 2000, ‘the much-advertised heating of the earth by the man-made carbon-dioxide ‘greenhouse’ fails to occur; instead, there is renewed concern about cooling and an impending ice age.”
A thought policeman who uses Wikipedia to promote the man-made global warming hypothesis has now added that quote to my biography, with the comment: “After his prediction was proven wrong, Calder participated in the polemic documentary film The Great Global Warming Swindle. He also co-authored The Chilling Stars.”
