You need to be more sceptical of things you read online in news articles or hear from your mates at the pub.

The below paper examines the source.
"THE MYTH OF THE 1970s GLOBAL COOLING SCIENTIFIC CONSENSUS"

A quote from the abstract
"An enduring popular myth suggests that in the 1970s the climate science community was predicting “global cooling” and an “imminent” ice age, an observation frequently used by those who would undermine what climate scientists say today about the prospect of global warming. A review of the literature suggests that, on the contrary, greenhouse warming even then dominated scientists' thinking as being one of the most important forces shaping Earth's climate on human time scales"

So whilst fears of cooling may have been the topic of choice amongst your peers, the scientists were not saying this.

Again, be sceptical of the things you hear. A quick search in google scholar will provide you some good scientific sources.
