An article carried in our DTN ag news segment over the Thanksgiving holiday weekend on a producer attitude survey featured an idea that needs some clarification. The idea was voiced in the article portion on producer attitudes regarding global warming. Here is the paragraph in question:
In June 1974, Time magazine wondered, "Another Ice Age?" In April 1975, Newsweek suggested the polar ice caps be melted for drinking water in the coming big freeze. (Newsweek issued a correction 31 years later, in 2006, saying it had been "spectacularly wrong.")
The reason I bring this paragraph up is that I have heard more than one reference to this "Ice Age" idea that was expressed by news magazines now almost 40 years ago as emanating from the scientific community. And this idea has been publicized to cast doubt on global warming research and conclusions. Such an idea is incorrect.
As reported by USA Today in February 2008, National Climatic Data Center (NCDC) researcher Thomas Peterson surveyed dozens of peer-reviewed scientific articles from 1965 to 1979 and found that only seven supported global cooling, while 44 predicted warming. Peterson found that 20 others were neutral in their assessments of climate trends.
The total--71 articles reviewed. 44 (62 percent) predicted warming. 20 (28 percent) were neutral. And 7 (10 percent) predicted global cooling.
