Global Warming & Arctic region: Concerns & Opportunities

Global Warming & Arctic region

IE | Prelims + Mains | GS3 > Environmental Pollution & Degradation | GS3 > Climate Change

Present situation of Arctic

  • The region is warming up twice as fast as the global average.
  • Since 1980, the volume of Arctic sea ice has declined by as much as 75 per cent.
  • The Northern Sea Route (NSR) which would connect the North Atlantic to the North Pacific through a short polar arc is slowly opening due to the melting of ice.
  • A trickle of commercial cargo vessels has been going through NSR every summer since the last decade.
  • Models predict that this route could be ice free in summer by 2050.

Concerns

  • The loss of ice & the warming waters will affect sea levels, salinity levels, & current precipitation patterns.
  • The Tundra is returning to swamp ( loss of forest loss of carbon sink), the permafrost is thawing ( exposing the subsurface carbon sinks), & wildfires are devastating interior Canada & Russia.
  • The phenomenally rich biodiversity of the Arctic region is under serious threat.

New Opportunities

  • The opening of the Arctic presents huge commercial & economic opportunities, particularly in shipping, energy, fisheries, & mineral resources.
  • Commercial navigation through the NSR is the most tempting: The distance from Rotterdam to Yokohama will be cut by 40 per cent compared to the Suez route.
  • Access to unexploited resources
  • Unexplored oil & natural gas deposits are estimated to be 22% of the world’s unexplored resources, mostly in the Arctic ocean
  • mineral deposits including 25 per cent of the global reserves of rare earths are buried in Greenland.

Challenges associated with new opportunities

  • Navigation conditions are dangerous & restricted to the summer.
  • Lack of deep-water ports, a need for icebreakers, shortage of workers trained for polar conditions, & high insurance costs add to the difficulties.
  • Mining & deep-sea drilling carry massive costs & environmental risks.
  • The complication is that, unlike Antarctica, the Arctic is not a global common.
  • There is no treaty that governs it, only the UN Convention of Law of the Sea (UNCLOS) deals it.

  • Large parts of it are under the sovereignty of the five littoral states — Russia, Canada, Norway, Denmark (Greenland) & the US & exploitation of the new resources is well within their rights.
  • They have put in overlapping claims for extended continental shelves, & the right to sea-bed resources.
  • In 2007, Russia embedded a flag on the seabed below the North Pole to bolster its claim.
  • The US, not a party to UNCLOS, is under pressure to strengthen its Arctic presence.
  • Russia claiming that the NSR falls within its territorial waters (the US believes it lies in international waters).
  • China has been projecting the Polar Silk Road as an extension of the BRI for economic advantage.

Impact on India

  • India’s extensive coastline makes us vulnerable to the impact of Arctic warming on ocean currents.
  • Research in Arctic melting will help us understand of climatic changes in the Third Pole — the Himalayas.
  • The strategic implications of an active China in the Arctic & its growing economic & strategic relationship with Russia are self-evident.
  • India has observer status in the Arctic Council, which is the predominant inter-governmental forum for cooperation on the environmental & development (though not the security) aspects of the Arctic.
