Apparently the new date is 2030: The original estimates of the timing of glacier melt were based on two things: modeled projections of the glaciers’ response to warming, and direct observations of glacial retreat. A 2003 report was based on modeling a scenario of doubling pre-industrial atmospheric CO2 levels by 2030, which would have melted the park’s major glaciers – and presumably the minor ones, too – by 2030. https://www.yaleclimateconnections.org/2019/09/fact-check-no-the-glaciers-are-not-growing-in-glacier-national-park/ https://www.yaleclimateconnections.org/2019/09/fact-check-no...

Another study from 2010 seems to have given 2080 https://www.usgs.gov/centers/norock/science/retreat-glaciers-glacier-national-park?qt-science_center_objects=0#qt-science_center_objects https://www.usgs.gov/centers/norock/science/retreat-glaciers... It seems we may have quite a bit of understanding to gain regarding glaciers. I'm not sure if the 2010 study is more reasonable (I'm no expert) but I think enough time has elapsed in the 2003 study to say that the estimations in it didn't pan out based on the observed values in 2015.
