Glacier NP explains -- partly -- why signs predicting date of glaciers' disappearance were changed
Climate science is just that, science, which ebbs and flows through the refinement of technology and physical observation. But the Trump administration's refusal to recognize the science its land-management agencies conduct neither ebbs nor flows; you could say it's frozen in place. Sadly, that clamp down is preventing a thorough discussion of what's going on with the glaciers at Glacier National Park.
A few weeks ago, there was something of a furor from some media over the decision by staff at Glacier to remove interpretive displays that had said "computer models indicate the glaciers will all be gone by the year 2020." Fanning the uproar was that the Park Service had "quietly" removed the display.
