Scientists predicted global cooling and were wrong, so they are wrong about global warming
A persistent argument designed to discredit the field of climate science is that scientists predicted an ice age in the 1970s. So popular in fact that it ranks an impressive #7 in the most cited skeptic arguments. The logic goes that climate scientists got it completely wrong predicting global cooling in the 1970s (it started warming instead). Hence climate science can't be trusted about current global warming predictions. Setting aside the logical flaws of such an ad hominem argument, was there any consensus among 70s climate scientists predicting global cooling? [...] The paper surveys climate studies from 1965 to 1979 (and in a refreshing change to other similar surveys, lists all the papers). They find very few papers (7 in total) predict global cooling. This isn't surprising. What surprises is that even in the 1970s, on the back of 3 decades of cooling, more papers (42 in total) predict global warming due to CO2 than cooling.
