Earlier quoted context omitted.
Also, the ozone holes, acid rain, and things like Y2K. “This thing would have been very bad, but we (expensively, with great effort) fixed it, so it was okay” somehow becomes, in the public imagination, “this was not a real thing”.
Yup, loads of examples! I really like the population levels of threatened species because the charts for that are so incredible concrete and demonstrate the point very well in a very concise manner. Something like Y2K or acid rain is a lot less concrete.
The most outlandish sensationalist claims grab mainstream attention (no snow by 2020) and when the predictions turn out not to be true, the advocates retreat to "well it was never a mainstream model". Classic Motte & Bailey. So in this case, the models that predict doom & gloom in the mid-term future saturate the media (Bailey) and when the predictions turn out to be false, it was claimed to never be a mainstream model (Motte).
If it's not a mainstream model, why are news outlets scaring the population with these fringe models? Even the IPCC director is chiding the doomsayers to not be so extreme in their prognostications.
Weather reports now use scary red color schemes to represent highs when a few years ago, higher highs were represented with a sun & blue color scheme. News coverage of heat outweigh coverage of summer time record lows & record sized hail in the mid US & Europe.
