"How glaciers grow. Snow falls each year and doesn't all melt, accumulates, "

Yes; if a soldier dies, he gets covered by snow. That says nothing about whether or not the glacier is gaining or losing mass.

This figure shows the cumulative change in mass balance of a set of "reference" glaciers worldwide beginning in 1945. The line on the graph represents the average of all the glaciers that were measured. Negative values indicate a net loss of ice and snow compared with the base year of 1945. For consistency, measurements are in meters of water equivalent, which represent changes in the average thickness of a glacier. The small chart below shows how many glaciers were measured in each year. Some glacier measurements have not yet been finalized for the last few years, hence the smaller number of sites.
