That's not a very accurate representation of what was going on. The ones predicting cooling agreed with the ones predicting warming on the effect increasing greenhouse gases would have (warming).
The difference was that the ones predicting cooling assumed that the growth in particulate matter pollution would continue to outpace the growth in greenhouse gases, and so the cooling effect from particulates would be stronger than the warming effect from the greenhouse gases.
Starting around the '70s much of the world made a major effort to get particulates under control and the particulates levels went way down.
