No Ice Age For 5,000 Years Scientist Says 28 Jul 1976

“No ice age for 5,000 years, scientist says” The Canberra Times (ACT : 1926 – 1995) 28 July 1976: 9. Web. 31 Aug 2024 https://trove.nla.gov.au/newspaper/article/110819193?searchTerm=no%20ice%20age&searchLimits=#

The world need not fear the onset of another ice age for at least 5,000 years, according to an ANU scientist who believes he has developed the first firm explanation for past ice ages.
The scientist, Dr John Chappell, senior lecturer in the Department of Geography in the School of General (Studies, believes that changes in the earth’s orbit were the primary cause of earlier ice ages.
These changes were accompanied by changes in the surface temperature of the North Atlantic, with the two being combined before the ice ages could begin.
The results of his work on the Huon Peninsula in Papua New Guinea, which led to his theory, are reported in the latest issue of the ANU Reporter.
His studies were conducted by matching past moves in the earth’s orbit against terraces on the Huon Peninisula which correspond with different sea levels in the earth’s history.
The rises and falls in the sea levels correspond ed with periods during which the ice ages “sucked up” water and lowered sea levels and times when meltings caused rises in the levels.
Dr Chappell has been studying the peninsula for 10 years. He said computers were able to accurately tell what variations in orbit there had been over the past million years and to predict variations during the next million.
