Question 3Discuss the effects of melting glaciers on the environment and the measures that can be taken to address this issueGS1GS1
The melting of glaciers due to climate change has serious implications for the ecosystem and human security. Discuss the effects of melting glaciers on the environment and the measures that can be taken to address this issue.
Main Body
Glaciers are ice-spark that store upto 90% of freshwater reserves and help maintain heat balance of the atmosphere.
Implications of melting glaciers:
As per IPCC, most of the glaciers will vanish by the end of 21st century.
(a) Ecosystem impact:
1Increased addition of freshwater => slowing down of density currents => disturbs marine ecosystem & surface temperature over oceans.
2The polar biodiversity => snow bears, wolves, seals threat of extinction due to disappearance of glaciers.
3Release of Arctic enough [illegible] feedback mechanism =>
further warming of the climate
(A) Thinning of ozone side => in [illegible] radiation shred.
(b) Human Society impact:
1Rising sea level => submergence of coastal cities like Mumbai, [illegible], LA etc.
2Impact on agro production due to uplifting fresh water reserves
3Increased intensity of hydro-logical floods and agricultural droughts.
4Loss of drinking water reserves.
Measures:
1Reduction of black carbon coat in silty areas.
2Strict implementation of decarbonization to reverse warming.
3Use of goethite to maintain albedo of glaciers.
4Hydrological management.
