glacier melting

Glacier melting occurs when rising global temperatures cause the ice to lose more heat than it gains, leading to a decrease in glacier mass. This is driven by climate change, where increased greenhouse gases trap more heat in the atmosphere. When temperatures are high, surface ice melts into water, which can flow into the ocean, causing sea levels to rise. Melting also involves internal ice weakening and breaking apart over time. This process is influenced by local factors like sunlight, albedo (reflectivity), and the glacier's position. Overall, glacier melting is a clear indicator of changing climate conditions affecting the Earth's cryosphere.
