The overpopulation people predicted catastrophe and it didn't come to pass on schedule because we borrowed from the future with unsustainable agricultural practices. (Also a lot of the early ones were super racist, but that's a separate issue.)

The peak oil people predicted catastrophe and it didn't come to pass on schedule because we borrowed from the future with fracking.

The climate change people update their catastrophe predictions every few years and then the data come back and it's WORSE than the predictions.
