> I'd love to have a look at the original publication that the USGS used when it decided to create those signs, but its buried so deep under partisan schadenfreude that I can't find it to even analyze it.

Don't you and the guy you responded to want the same thing: answers from the scientific community? You can criticize the right wing news sources all you want... the existence of the signs saying the glaciers were going to disappear is pretty indisputable. Clearly, someone at some point had enough belief in that prophesy that they made a sign.
