A science magazine published by scientists in 1975 who stated that an Ice Age was coming.
If you believe that, you're dumber than you appear to be. Those "science magazines" printed on newsprint, hired writers to read science and write about it. No real scientist wrote those things.
It should be a wake-up call for you, that the only stuff that supports your ideas of an impending ice age, are articles written by non-scientists.
As you learned, even in the 70s, the majority of climatologists thought that warming was on the way.
CLIMATE CHANGE: ARE WE ON THE BRINK OF A PRONOUNCED GLOBAL WARMING?
W.S.Broecker
Science 189 (1975): 460-463
If man-made dust is unimportant as a major cause of climatic change, then strong case can be made thata the present cooling trend will, within a decade or so, give way to a pronounced warming induced by carbon dioxide. By analogy with similar events in the past, the natural climatic cooling which, since 1940, has more than compensated for the carbon dioxide effect, will soon bottom out. Once this happens, the exponential rise in the atmospheric carbon dioxide content will tend to become a significant factor and by early in the next century will have driven the mean planetary temperature beyond the limits experienced during the last 1000 years.
Science, as you might know, is one of the world's premier scientific journals, peer-reviewed and very difficult in which to publish. Compare to your newsprint "school science magazine" not even written by scientists. Notice that a real scientist got it right, and his predictions were spot on.
Models, you know. There's lots more. How much more do you want to see?
