So of the 18 predictions none are from climatologists, none are in published research but rather in comments to magazines and speeches, and half are from 2 people, Paul Erlich (a biologist) and Kenneth Watt (an ecologist). And some of them are not even wrong, for instance concerns about population growth or rainforest loss at the rate it was occurring at the time. The headline here is “some random scientists were wrong about something 50 years ago”. The fact the comparison is even made between these comments and the published evidence base for climate change, indicates more about the person making the criticism than the target of the criticism. These are the same kind of people who think that political commentators on rolling news are making a meaningful contribution to scientific debate.
