Rising temperature → Melting of glaciers
↓ less albedo → Positive-feedback (OOP)
Effect of ice melting of glaciers:
Environment:
↓ Melting glaciers → release of harmful carbon dioxide → Water pollution
↓ Sea level rise → around 4mm/yr
↓ Coastal erosion → loss of habitat
↓ Threatening biodiversity e.g., Polar bear, Snow Leopard
↓ Reduce albedo → more temperature → more climate change
Thus the melting of glaciers affects the global climate & environment and human society through interconnected changes.
Creation of more glacial lakes → threat of glacial lake outburst floods
↓ Floating increased land instability → landslides & avalanches
Human Society → Discusses lake landslides, avalanches
↓ change in size flow → drinking water crisis
↓ Damage to infrastructure → loss of life & livelihood e.g., Uttarkhand floods
↓ Land abundance → hampering normal life e.g., Tochimeth Crisis
↓ Sea level rise → threat to coastal communities & livelihoods
