SUMMARY
Modern doomsayers have been predicting climate and environmental disaster since the 1960s. They continue to do so today.
None of the apocalyptic predictions with due dates as of today have come true.
What follows is a collection of notably wild predictions from notable people in government and science.
More than merely spotlighting the failed predictions, this collection shows that the makers of failed apocalyptic predictions often are individuals holding respected positions in government and science.
While such predictions have been and continue to be enthusiastically reported by a media eager for sensational headlines, the failures are typically not revisited.

And…are we in for another FAKE news flash, if the global warming starts to fade into the past?
That Arctic Blast throttled us last Jan/Feb, so the Sooth Sayers of he past are in way over their heads!

Sounds like something the global warming squirrels would FAKE us over with!
Whomever did the dirty deed…
Seems to have a facination for trying to become the modern day Nostradamus?!
