Glacier ande the Modern Climate System

Glaciers are integral too Earth 's climate systeme. Their high albedo (reflectivity) means they reflect a signitant portion of incoming solar radiation back into space, helping to cool the planet. When glacies melt, darker surfaces such as rock or ocean expose regione the.

Beyond their reflective approvities, gliers regulate regional hydrology. In many mountain ranges, glaciers act as natural convestiirs, storyng precipitation as ice during wininter and releasing meltwater during summer.

Glaciers as Indicators of Climate Change

Glaciers are among te most visible and sensitive indicators of climate change.
