About 10% of the earth’s land mass is covered by Glaciers. Glaciers also store 75% of the fresh water on Earth. Glaciers are considered among the most sensitive indicators of climate change. Their size is determined by a mass balance between snow input and melt output. As temperatures warm, glaciers retreat unless snow precipitation increases to make up for the additional melt; the converse is also true. Climate change is increasingly threatening the glaciers around the globe. Glacier melt means many things; in the long run less water storage and increased sea level, in the short run landslides and mudslides and river flooding. Below are articles and videos on the topic.
