Even if we assume that 50 years ago the scientific consensus supported cooling, so what? Better theories backed by new data has a tendency to shift scientific opinions about most stuff.

A survey of studies made from 1965 to 1979 showed a clear majority talked of global warming and not cooling.

A New York Times article from 1956:

According to a theory which was held half a century ago, variation in the atmosphere's carbon dioxide can account for climatic change. The theory was generally dismissed as inadequate. Dr. Gilbert Plass re-examines it in a paper which he publishes in the American Scientist and in which he summarizes conclusions that he reached after a study made with the support of the Office of Naval Research. To him the carbon dioxide theory stands up, though it may take another century of observation and measurement of temperature to confirm it.
He mentions humans adding 30% of CO2 in every century while it is more like 50 or 60% now.
