Study: Global cooling a 1970s myth

Feb 21 ,Space & Earth science


A U.S. climatologist said there was no consensus in the 1970s that the Earth was headed for a new ice age.

Thomas Peterson of the National Climatic Data Center said a survey of scientific journals of the era showed that only seven supported global cooling, 44 predicted warming and 20 others were neutral, USA Today reported Thursday.

"An enduring popular myth suggests that in the 1970s the climate science community was predicting 'global cooling' and an 'imminent' ice age, an observation frequently used by those who would undermine what climate scientists say today about the prospect of global warming," Peterson said in the report, co-authored by William Connolly of the British Antarctic Survey and John Fleck of The Albuquerque Journal.

The study, which will be published in the Bulletin of the American Meteorological Society, said a review of the literature suggests that greenhouse warming even then dominated scientists' thinking.

Don't judge a brook by its color -- brown waters are more natural
Over the last 20 years lakes and streams in remote parts of the UK, southern Scandinavia and eastern North America have been increasingly stained brown by dissolved organic matter. In this week’s Nature journal (22 November) an international team, led by researchers from UCL (University College London) and the US Environmental Protection Agency (EPA), demonstrates that the colour change is indicative of a return to a more natural, pre-industrial state following a decline in the level of acid rain.

"Doubt is our product," stated a tobacco industry memo from 1969. For half a century, the tobacco industry tried to muddy the link between smoking and cancer. Now, with that effort long since failed, cigarette producers facing dozens of potentially ruinous lawsuits are once again attempting to manufacture doubt.
