A glacier is permanent ice that moves under its own weight. Four of the 25zero mountains still have permanent ice although this no longer moves as not enough new snow and ice is accumulating. These have been included as they were glaciers and their changed status is a clear indication of their decline which is what 25zero wants to highlight.
The 25 years quoted in the project title is an average figure for how much longer the worlds equatorial glaciers will last. In one or two cases the glaciers may last longer while the majority will last far less than 25 years.
