global cooling scientific consensus." Bulletin of the American
Meteorological Society 89(9): 1325-1337.
There was no scientific consensus in the 1970s that the Earth was headed
into an imminent ice age. Indeed, the possibility of anthropogenic warming
dominated the peer-reviewed literature even then.
