As I understand it, the claim that there was to be a coming ice age was based on our increased rate of particulate matter into the atmosphere, not greenhouse gases. The claim was that in addition to greenhouse gases, we were also exponentially increasing soot, aerosols, and other light dampening particulate matter. They argued that the C02 emissions would increase the temperature, but that cooling particulate matter pollution would outpace the warming greenhouse-gas pollution.
We've very much curbed out aerosol, but increased our greenhouse-gas pollution. I very much doubt that their analysis was correct to begin with, and I doubt had we not curbed the aerosol pollution, we'd be facing an ice age today - but I'm just some jerk on the internet - I could easily be wrong! Right or wrong, the first paragraph above is how I understand the argument to have been made at the time.
