Different glaciers are behaving differently. Today, some are gaining mass (ice), while most are losing it. At what point this became the case globally, it is difficult to say. I would guess 50-100 years ago the majority of worldwide glaciers were in net mass loss. Remember though that it is not just broad climatological forces that control glacial melt.

I think that glaciers don't melt in the summer because glaciers form where it's cold like year long so it would be cold in the summer too. In cold weather ice doesn't melt.

Water can speed up the rate at which glaciers melt. Whether the water is acidic or not has no effect.
