Heritage sites at risk from global warming: study

Why in news?
  • According to research published in the journal Earth’s Future. glaciers are set to vanish from almost half of U.N.-designated World Heritage sites in less than a century if greenhouse gas emissions are not cut.
  • Sites likely to be affected include the Grosser Aletschgletscher in the Swiss Alps and Greenland’s Jakobshavn Isbrae.

  • Wake-up call:
    (1) IUCN said that data should act as a wake-up call for nations to step up their commitments to prevent climate change.
    (2) Losing these iconic glaciers would be a tragedy and have major consequences for the availability of water resources, sea level rise and weather patterns.
  • Risks for World Heritage sites:
    (1) Researchers plotted glaciers at World Heritage locations identifying a total of some 19,000 over 46 sites.
    (2) Nearly half the World Heritage sites — 21 out of a total of 46 that have glaciers — will lose all their ice by 2100 under a high emissions scenario.
    (3) Some of the well-known beauty spots include:
  • Los Glaciares National Park in Argentina.
  • The Canadian Rocky Mountain Parks.
  • Te Wahipounamu in South West New Zealand.
  • Falling volume:
    (1) The research found significant melting is expected in all scenarios, with between 33% and 60% of the total ice volume in 2017 lost by 2100.
    (2) The findings should highlight the threat posed by global warming.
