That's massively misleading.

The scientists that predicted that predicted it because they forecast that the cooling effect from particulate pollution such as smog would be bigger than the warming affect from greenhouse gases.

Not long after, we actually made fairly strong clean air laws and greatly cut back the particulate emissions, thus changing the assumptions that the cooling predictions were based on. The scientists that had predicted cooling, which had only been a small minority, then agreed with the rest that we'd have warming (assuming we didn't also get the greenhouse gases dealt with).
