CNN has the story Glacier National Park is replacing signs that predicted its glaciers would be gone by 2020 [cnn.com]

The signs at Glacier National Park warning that its signature glaciers would be gone by 2020 are being changed.

The signs in the Montana park were added more than a decade ago to reflect climate change forecasts at the time by the US Geological Survey, park spokeswoman Gina Kurzmen told CNN.

But the glacier warning isn't being removed entirely, she told CNN. Instead, the new signs will say: "When they will completely disappear depends on how and when we act. One thing is consistent: the glaciers in the park are shrinking.

According to famous philosopher of science Karl Popper [utm.edu], scientific theories require predictions that risk being wrong. This was one such prediction. Another that did not fare well [masslive.com] about Mt. Kilimanajaro reads [sciencemag.org]:

if current climatological conditions persist, the remaining ice fields are likely to disappear between 2015 and 2020

What concrete and risky predictions of climate science do you know that came true?
