Author of 1975 Newsweek global cooling article, Peter Gwynne, issues partial ‘mea culpa’ — Rails on ‘deniers’ & promotes Michael Mann & Now says of cooling fears ‘scientists now know that they were seriously incomplete’

However, both types of warming deniers, along with policymakers who have consistently opposed any regulation designed to reduce acid rain, the destruction of the ozone layer, and other perceived ills, have consistently used the articles – particularly mine – as ammunition.

But that’s just one line of attack. Mann suffered another starting in 1998, after he published an article in the journal Nature; that included a “hockey stick” model that demonstrated a dramatic increase in the rate of recent global warming.
