Yes, and it's even worse than that. The ice also reflects and awful lot of energy back into space due to being highly reflective. When that the ice is gone, that exposes darker surface which is a lot less reflective. That will also result in lot more heating.
The more things warm up, the more things will warm up in a vicious cycle with many positive feedback loops. Sadly a lot of it seems irreversible at this point.

More desert dust being carried at higher altitudes - Himalayas, Alps - is also increasing the darkness aka heating of the glacier surfaces, thus speeding their melting...
