I interviewed a scientist about this a few weeks ago and wrote about it here http://www.jehovahs-witness.com/6/125818/1.ashx.
The problem is that scientists do not (and can not) really KNOW. So all of the protestations that "everyone" believes this or that are hollow. As the article from 1975 illustrates, "scientists" change their notions of what is going on regarding climate.
The scenario has to do with the fresh water that is hitting the oceans from the melting polar ice caps.
Interesting that the 1975 article was faulting the government for not responding to the impending ice age. One suggestion was to speed up the melting of the ice caps by "painting" them with black soot etc.
Whether the world is warming (today’s scientists) or heading for an ice age (scientists from 1975) it seems that there are precious few facts and plenty of speculation….and implied "ad hoiminum" attacks (for example, scientists who do not agree are not in the know). Needless to say, scientists have been wrong before.
At
http://www.time.com/time/covers/1101041011/story.html it reads:Albert Einstein remarked in 1932 that "there is not the slightest indication that nuclear energy will ever be obtainable." Thomas Edison thought alternating current would be a waste of time.""
What resonates as disingenuous is folks like Al Gore acting as if they "KNOW" such and such.
The final verdict on climate change is far from in….even as the 1975 article illustrates.
