CLIMATE OF THE POLAR REGIONS
There is growing evidence that the climate of the polar regions is changing rapidly as an element in the
global warming process. In the northern hemisphere there is a marked warming trend, enhanced by the
ice-albedo feedback mechanism, and also a cyclic variability associated with the Arctic Oscillation. This
manifests itself in changed atmospheric circulation patterns, changes in air temperature and precipitation,
and changes in sea ice thickness, ocean structure, glacier mass balance, snowlines and permafrost depth.
In the Antarctic the warming trend appears to be limited to the Antarctic Peninsula for reasons not clearly
known. We welcome papers on observations and modelling of polar climatic variability, as well as the
impacts of this variability on the polar environment (e.g. ocean, ice, snow, permafrost properties, glacial
retreat) and on the global environment (e.g. rate of sea level rise). The emphasis will be on interannual and
interdecadal variations of both atmosphere and ocean, and the relationship between climate change and
ocean processes.
