Buck Throckmorton tells us in the Ace of Spades blog that
Glacier National Park is removing "glaciers will be gone by 2020" signs
The glaciers were supposed to be gone by now, based on the most super-scientific models according to infallible scientists. It was such a scientific fact - based on their climate “models” - that they put up these signs at Glacier National Park stating that the glaciers would be gone by the year 2020. Of course they were wrong, because climate science is a fraud, a hoax, and a scam. But anyone who didn’t believe the glaciers would be gone by 2020 was a “science denier.”
Rather than manually remove their apocalyptic signs, maybe they should have manually removed the glaciers instead, so that their prophecy would come true.
