But I have researched glaciers for decades worldwide, and I can tell you glaciers are not just thermometers, and ice does not just melt. As glaciers are more and more iconized with climate change, everything else about a glacier seems to fall away their immense diversity and their complexity. Today, thousands of tourists arrive each year to experience the landscape and interact with ice, and locals are finding their icy neighbors to be objects of global attention and sources of lucrative income.

Under IPCC scenario RCP 8.5 (a more business-as-usual scenario), global sea level contributions from glaciers will be 216 44 mm by 2100 AD14. At times, Ive returned to glaciers Ive researched for years to find them unrecognizable and withered, and this breaks me.
