The horizontal line across the Garden Wall on the other side of the valley is the Going-to-the Sun Road, which I finally drove—3rd time’s the charm. This year the dramatically scenic road opened on 13 June with little ice & snow visible in July. Just over the wall in Many Glacier, old photos show the many large glaciers are now very small, rapidly melting glaciers. My son and I rode horseback up in 2018, and the area should be renamed Many Lakes. Combined with its neighbor across the border, Waterton Glacier International Peace Park is still a UNESCO World Heritage Site, despite the obvious melting problem.

Melting ice and glaciers are one of the tipping points that will flip our Climate Crisis into a catastrophe. Consider the Arctic ice cap. Every year recently, the multi-year ice has been shrinking at an accelerating rate. Eventually, the ice will disappear in summer. Then the same energy that currently raises ocean surface temperatures by 1° will raise it by a multiple of that amount. There are two reasons for that. First, the white ice will no longer reflect the sun. Second, the existing ice will no longer be there to act as a temperature break. When you boil water with ice, it takes something like three times the energy as water without ice, because most of the energy goes into melting the ice first. So, not only is it bad that glacial ice is melting due to flooding and dry rivers in the fall, but once the ice is gone, the surface temperature rise will accelerate much more rapidly. Please, reduce your carbon footprint.
