No, nobody here probably remembers that. For one thing, it really didn't happen, except in some media scare stories. The citation below says there were all of 7 scientific papers making that claim.

From the skepticalscience blogsite, Re: What 1970s science said about global cooling (http://www.skepticalscience.com/What-1970s-science-said-about-global-cooling.html)

I recommend any who honestly want both sides of the story to look at this site, which answers every critics' arguments. Whether satisfactorily or not, I'd say yes, but your mileage may vary.

Posted on 26 February 2008 by John Cook

A persistent argument designed to discredit the field of climate science is that scientists predicted an ice age in the 1970s. So popular in fact that it ranks an impressive #7 in the most cited skeptic arguments. The logic goes that climate scientists got it completely wrong predicting global cooling in the 1970s (it started warming instead). Hence climate science can't be trusted about current global warming predictions. Setting aside the logical flaws of such an ad hominem argument, was there any consensus among 70s climate scientists predicting global cooling?
The evidence for global cooling consensus

Most cited is a 1975 Newsweek article The Cooling World that suggested cooling "may portend a drastic decline for food production":

"Meteorologists disagree about the cause and extent of the cooling trend… But they are almost unanimous in the view that the trend will reduce agricultural productivity for the rest of the century."

A 1974 Times Magazine article Another Ice Age? painted a similarly bleak picture:

"When meteorologists take an average of temperatures around the globe, they find that the atmosphere has been growing gradually cooler for the past three decades. The trend shows no indication of reversing. Climatological Cassandras are becoming increasingly apprehensive, for the weather aberrations they are studying may be the harbinger of another ice age."

However, these are media articles, not peer reviewed scientific papers. Does a consensus on global cooling emerge from the scientific literature?
Skeptical quote mining of 1970s scientific literature

Most mentioned is Rasool 1971 which projected that if aerosol levels increased 6 to 8 fold, it may trigger an ice age. While Rasool underestimated climate sensitivity to CO2, its basic assertion that the climate would cool with a dramatic increase of aerosols was correct. However, aerosol levels dropped rather than increased. More on Rasool...

A 2003 Washington Post op-ed by James Schlesinger, Climate Change: The Science Isn't Settled, quoted a 1972 National Science Board report as follows:

"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 glacial age."

The full quote from the report is as follows:

"Judging from the record of the past interglacial ages, the present time of high temperatures should be drawing to an end, to be followed by a long period of considerably colder temperatures leading to the next glacial age some 20,000 years from now. However, it is possible, or even likely, that human interference has already altered the environment so much that the climatic pattern of the near future will follow a different path.

For instance, widespread deforestation in recent centuries, especially in Europe and North America, together with increased atmospheric opacity due to man-made dust storms and industrial wastes, should have increased the Earth’s reflectivity. At the same time increasing concentration of industrial carbon dioxide in the atmosphere should lead to a temperature increase by absorption of infrared radiation from the Earth’s surface.

When these human factors are added to such other natural factors as volcanic eruptions, changes in solar activity, and resonances within the hydro-atmosphere, their effect can only be estimated in terms of direction, not of amount"

Schlesinger's op-ed has been quoted widely including James Inhofe's Senate testimony. Skeptic citing of the scientific literature have taken conclusions out of context, overlooking qualifications and stated uncertainties. What does a broader look at the scientific literature reveal?
A new paper exposing the myth of 70s global cooling

Over time, William Connelly has been steadily documenting 70s research predicting global cooling. It's a rich resource but as he admits, could be more accessible. Now he has collaborated with Thomas Peterson and John Fleck to publish The Myth of the 1970's Global Cooling Scientific Consensus, due to be published in the Bulletin of the American Meteorological Society.

The paper surveys climate studies from 1965 to 1979 (and in a refreshing change to other similar surveys, lists all the papers). They find very few papers (7 in total) predict global cooling. This isn't surprising. What surprises is that even in the 1970s, on the back of 3 decades of cooling, more papers (42 in total) predict global warming due to CO2 than cooling. </div></div>

Documents obtained by Greenpeace show prominent opponent of climate change was funded by ExxonMobil, among others

Oh Boy!!!

<div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body">One of the world's most prominent scientific figures to be sceptical about climate change has admitted to being paid more than $1m in the past decade by major US oil and coal companies.

Dr Willie Soon, an astrophysicist at the Solar, Stellar and Planetary Sciences Division of the Harvard-Smithsonian Centre for Astrophysics, is known for his view that global warming and the melting of the arctic sea ice is caused by solar variation rather than human-caused CO2 emissions, and that polar bears are not primarily threatened by climate change.

But according to a Greenpeace US investigation, <span style='font-size: 14pt'>he has been heavily funded by coal and oil industry interests since 2001, receiving money from ExxonMobil, the American Petroleum Insitute <span style='font-size: 17pt'>and <span style="color: #990000">Koch Industries</span></span> along with Southern, one of the world's largest coal-burning utility companies. </span>Since 2002, it is alleged, every new grant he has received has been from either oil or coal interests.

In addition, freedom of information documents suggest that Soon corresponded in 2003 with other prominent climate sceptics to try to weaken a major assessment of global warming being conducted by the UN's leading climate science body, the Nobel prize-winning Intergovernmental Panel on Climate Change.

Soon, who had previously disclosed corporate funding he received in the 1990s, was today reportely unapologetic, telling Reuters that he agreed that he had received money from all of the groups and companies named in the report but denied that any group would have influenced his studies.

"I have never been motivated by financial reward in any of my scientific research," he said. "I would have accepted money from Greenpeace if they had offered it to do my research." He did not respond to a request from the Guardian to comment.

Documents provided to Greenpeace by the Smithsonian under the US Freedom of Information Act (FoIA) show that the Charles G Koch Foundation, a leading provider of funds for climate sceptic groups, gave Soon two grants totalling $175,000 (then roughly £102,000) in 2005/6 and again in 2010. In addition the American Petroleum insitute (API), which represents the US petroleum and natural gas industries, gave him multiple grants between 2001 and 2007 totalling $274,000, oil company Exxon Mobil provided $335,000 between 2005 and 2010, and Soon received other grants from coal and oil industry sources including the Mobil Foundation, the Texaco Foundation and the Electric Power Research Institute. </div></div>

It gets better.

Sounds like perjury to me.

If that is your point, then surely you must also agree that the IPCC is at least equally guiky?

06-29-2011, 02:49 AM
So the fact that it happened is proof that it never happened?

The doublethink is strong in you.
