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.
About 100 million years
glaciers are big and vary cold.
Large sheets of ice that do not melt are called glaciers. Glaciers are formed when snow accumulates over time and compacts into ice, flowing slowly due to gravity.
It is difficult to predict an exact year, but based on current trends, it is estimated that Glacier National Park could lose all its glaciers by 2030. This is due to ongoing climate change and rising global temperatures causing the glaciers to melt rapidly.

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.

No. Rocks need to reach very high temperatures in order to melt. Glaciers, being made of ice, are cold. Glaciers do, however, grind rocks down into smaller pieces quite easily.
