Having read a little further I find another category. Individuals will make predictions based on a tipping point. That is they will opine that if some action is not taken by time X, then something bad will happen by time Y. Unfortunately, the article with the 50 failed predictions claims they've failed by time X which is, of course, wrong at best.As is, so far, always the case, the "failed predictions" deniers claim have failed are not the predictions of climate scientists or were predictions made with serious qualifications that deniers ignore. But let's take a tour of your list.
You begin with Paul Ehrlich. Ehrlich was an ecologist. He didn't know diddly squat about climate science or much of anything else except how to sell books. Ehrlich is the author of the first four of your predictions.
The next three predictions come from a biologist, an "organizer" and another ecologist.
Next comes Kenneth Watt, a retired zoologist.
Next we get the Boston Globe, The Guardian, Time and Newsweek. Being reputable news sources, their articles have reasonable sources.
The first is James Lodge of the National Center for Atmospheric Research (NCAR) who, in 1970, warned that unaddressed air pollution could obscure the sun and reduce temperatures by the first third of the 21st Century. The problem with this prediction, of course, is that air pollution WAS addressed.
Next is a 1974 article by Anthony Tucker, the Guardian's Science Correspondent claiming that satellite data show that fall and winter are getting longer.
Time magazine from 1974 gets an entry for an editorial wondering if the bizarre and unpredictable weather the world had seen lately is indication of a coming ice age.
Next is a Newsweek article citing unnamed scientists to wonder aloud if the Earth is approaching a new ice age.
The next four are New York Times articles.
So, we've covered the first 18 of your "failed predictions" and found only one authored by someone even faintly resembling a climate scientist and his prediction was perfectly valid when made and failed because the air pollution that concerned him 54 years ago was dealt with. Not one, so far, is making predictions about global warming.
Surely we've seen enough of this claptrap.
