It really depends on what you mean by "scientific consensus". Nuclear scientists have famously run a Doomsday Clock since 1947 predicting that we're going to nuke ourselves to death soon. Is that a consensus, or do there need to be formal academic studies which claim to prove universal collapse is coming? (How could you build such a study? Does the equivalent exist for climate change?)

Equally importantly, not all predictions are of the "came and went" variety. The ozone layer had a collapse prediction, and that prediction was 100% true - but we responded to it, fixed it, and now the ozone layer is doing fine and expected to make a full recovery soon. It would have been a lot harder if advocates went around saying that the ozone layer is guaranteed to collapse unless we stop using refrigerators!
