A "global ice age" was never something that climatologists were seriously worried about, even in the 1970s. It was a media distortion based mainly on research into the possibility of an ice age in the distant future -- like, 10,000 years -- due to normal climate cycles. Even at the time, the much more immediate threat of anthropogenic global warming was recognized. See e.g. https://www.jstor.org/stable/26220900 https://www.jstor.org/stable/26220900 for a more detailed explanation of where this myth came from.
