INTERNATIONAL SYMPOSIUM - ARCTIC FEEDBACKS TO GLOBAL CHANGE
25-27 October 2001
Arctic Centre
Rovaniemi, Finland

Sponsored by:
The Nordic Arctic Research Programme (NARP 1998-2002) and
The Academy of Finland

Organizing committee:
Dr. Peter Kuhry, Arctic Centre, Rovaniemi (Chair)
Dr. Jens H. Christensen, Danish Meteorological Institute, Copenhagen
Prof. Jon Ove Hagen, University of Oslo
Prof. Timo Järvikoski, University of Oulu
Dr. Paul Wassmann, University of Tromsø

BRIEF OUTLINE

An intercomparison of GCM results shows a remarkable consensus that
suggests a significant polar amplification of the global warming signal
and increased precipitation for the Circum-Arctic region. If these
changes occur, they would cause large-scale alterations in arctic
ecosystem function, triggering both positive and negative feedbacks that
would affect climate at regional and global scales. The international
symposium will assess, through an interdisciplinary approach, our
current understanding of processes in the Arctic that represent a
feedback to Global Change (carbon balance, ocean currents, sea level,
albedo, others). The aim is to quantify these feedbacks in different
sectors of the arctic environment and in the Arctic as a whole.

PROGRAMME

October 25 and October 26, morning (sectoral approach; keynote speakers,
oral presentations, poster session)

  • Summary of GCM and RCM results for the Arctic
  • The marine sector (ocean carbon balance, DMS-emissions, sea ice
    albedo, deep water formation, etc.)
  • The terrestrial ecosystems (tundra and forest-tundra carbon balance,
    surface albedo and roughness, etc.)
  • The freshwater ecosystems (runoff, transport of organics and
    pollutants, effects on ocean productivity and deepwater formation, etc.)
  • The icecaps/glaciers (mass balance, effects on freshwater discharge,
    deepwater formation and sea level, etc.)

October 26, afternoon (integrated approach; discussion fora)

  • Greenhouse gas balance of tundra, forest-tundra and Arctic marine
    ecosystems, including effects of freshwater runoff and its chemistry
  • Albedo on land and sea, in relation to vegetation, snow, and sea-ice
    cover
  • Freshwater runoff from tundra, forest-tundra and Arctic
    icecaps/glaciers
    in relation to deepwater formation
  • The mass balance of arctic icecaps/glaciers and sea level
  • Effects of large-scale arctic environmental pollution on marine and
    terrestrial ecosystem function.

October 27 (synopsis)

  • Conclusions of discussion fora
  • Social perception in Arctic communities of climatic and environmental
    change
  • Results of the meeting
  • Important gaps in knowledge
  • International/Nordic network
  • Conference statement/press releases/publications
