I see a pattern here........................ 😉
I visited the Exit Glacier National Park in Alaska.
There is a long winding road to Park HQ and the trail to the toe of the glacier.
There is a sign indicating that in 1896, the toe was 2 miles from the present location. As you wind down that road there are other signs with the dates of the toe location.
The US Government has been aware of glacier erosion for more than a hundred years.
Ditto glacier National Park. There is awareness of glacial melting prior to the human inventions and large population.
