Introduction

Climate change is causing melting of glaciers at an unprecedented state felling a positive-albedo cycle.

15 words

Main Body

Rising temperatureMelting of glaciers
↓ less albedoPositive-feedback (OOP)

Effect of ice melting of glaciers:

Environment:

↓ Melting glaciersrelease of harmful carbon dioxideWater pollution
↓ Sea level risearound 4mm/yr
↓ Coastal erosionloss of habitat

↓ Threatening biodiversity e.g., Polar bear, Snow Leopard

↓ Reduce albedomore temperaturemore climate change

Thus the melting of glaciers affects the global climate & environment and human society through interconnected changes.

Creation of more glacial lakesthreat of glacial lake outburst floods
↓ Floating increased land instabilitylandslides & avalanches
Human SocietyDiscusses lake landslides, avalanches
↓ change in size flowdrinking water crisis
↓ Damage to infrastructureloss of life & livelihood e.g., Uttarkhand floods
↓ Land abundancehampering normal life e.g., Tochimeth Crisis
↓ Sea level risethreat to coastal communities & livelihoods
