This site is pretty bad. Every prediction is a "doomsday" prediction, and it simply marks them as wrong if the world hasn't ended by the specified date. Example, predicting the Hoover damn (Lake Mead) won't provide electricity if no action is taken. There have been significant efforts at water conservation. So now it's a "missed" prediction. Or predictions that X could happen in as little as Y years, establishing a lower bound. Y years passed, we'll call it missed. It would be interesting to see a meta-analysis of predictions and how accurate they turned out to be, but that isn't what this site is.
