12 words
Main Body
Thermokarst:
1Creates positive feedback loop leading to increasing temperatures
2Melting snow undoes albedo affect causing further heating and Melting
Growing relevance of thermokarst:
1Understand causes of arctic melting and take remedial measures.
2Understand phenomenon of arctic amplification understanding higher vulnerability of arctic.
3Collect data for scientific studies through arctic observation missions.
Eg: Timings of India
1Tackle GHG release from permafrost thawing of methane is released
2Tackle the threat of emergence of new diseases from release of bacteria virus from thawing.
3Tackle sea level rise due to melting of glaciers.
4Check destruction of civil ecosystem like Tundra and Taiga in arctic region.
5Analyse the impact on global oceanic circulations as it is capacity due to salinity change.
6Explore potential of shipping routes in Arctic undying travel trust cost
