Mains level : Consequences of climate change on Polar region



News

  • Scientists from 17 nations will take part in the year-long MOSAIC mission as they anchor the RV Polarstern ship to a large piece of Arctic sea ice to study climate change.

 MOSAiC mission

  • The MOSAiC mission stands for Multidisciplinary drifting Observatory for the Study of Arctic Climate.
  • It is a one-year-long expedition into the Central Arctic, planned to take place from 2019 to 2020.
  • For the first time a modern research icebreaker will operate in the direct vicinity of the North Pole year round, including the nearly half year long polar night during winter.
  • It comes about 125 years after Norwegian explorer Fridtjof Nansen first managed to seal his wooden expedition ship, Fram, into the ice during a three-year expedition to the North Pole.
  • MOSAiC will contribute to a quantum leap in our understanding of the coupled Arctic climate system and its representation in global climate models.
  • The focus of MOSAiC lies on direct in-situ observations of the climate processes that couple the atmosphere, ocean, sea ice, bio-geochemistry and ecosystem.

Why study Arctic climate?

  • The Arctic is a key area of global climate change, with warming rates exceeding twice the global average.
  • The observed rate of climate change in the Arctic is not well reproduced in climate models.
  • Many processes in the Arctic climate system are poorly represented in climate models because they are not sufficiently understood.
  • Understanding of Arctic climate processes is limited by a lack of year round observations in the central Arctic.
