Melting glaciers in the Alps

For Bloomberg, Laura Millan, Kyle Kim, and Armand Emamdjomeh mapped the projected extent of melting glaciers in the Alps. The risk of avalanches and rock slides has risen, which could lead to buried towns that reside below.

In the above, the outer border represents the 2010 extent of selected glaciers. The solid blue is the extent that researchers have projected by 2100.

I think the color scheme confused me at first, because I thought I was looking at land mass with ice on top. I wonder if a second shade to indicate the melted portions would be helpful, or maybe a flipped focus to only show the melt would highlight how much is disappearing.
