Totally untrue.
I just ran the most simple search I could using only the NY Times, only 1970-1975 and only articles with the precise words "Ice Age"in either the headline or the opening sentence.

Article revs theories about causes of ice ages and speculation about whether new ice age is due.
Far from having “almost no exposure in the popular culture” this topic generated at least one headline story per year in the NY Times alone. In actual fact the number of stories woudl have been far higher. These are only the storys that specifically use the words “ice age” in the headlines or opening sentence.
Far from having almost no popular exposure the new ice age was “widely publicized” according to the NY Times.
Far from having almost no popular exposure it was the subject of at least one NY times reviewed book.
Far from being an outlying theory it was a major focus of several conferences and the world’s authorities on global climate, inlcuding Broeker and the boffins at NOAA, felt the need to voice there opinions on the matter.
I don’t see why global warming proponents see the need to deny the truth of this matter. In the 1970s scientists were widely touting the possibility of new ice age in the popular media. Anyone who was alive then remembers this perfectly well and the most simple journal searches confirm the fact.
Saying that it was fringe theory that had no popular epxosure and that people who remember otherwise are deluded hardly gives any credibility to the people who make such outrageous claims.
One day I may run a full search for the 1970s for all popular press, but I think this search alone lays to rest any claims that the theory had no popular support and was only a fringe theory in the scientific community.
