Right in your link: "Some press reports in the 1970s speculated about continued cooling; these did not accurately reflect the scientific literature of the time, which was generally more concerned with warming from an enhanced greenhouse effect." i.e. even in the 70s scientist were worried about warming because they saw concerning data. people getting concerned out about nonsense in the press has been with us since there was a press (cf 80s satanic panic) ... but that doesn't mean people being concerned about something in the press is nonsense.
