- Abstract:
- Our ability to understand the potential for future abrupt changes in climate is limited by our lack of understanding of the processes that control them. The climate system appears to operate in quasi-stable modes, and may switch from one mode to another within a few decades. Recent evidence suggest that abrupt climate changes often occur when gradual causes push the earth system across a threshold. Studies, using paleo data, of past climate suggest that large and rapid (as fast as 10-20 years) changes have occurred and that changes in the Atlantic Meridional Overturning Circulation (AMOC) are a major contributing factor. A better understanding of the processes that 'drive' the AMOC is of key importance. Examination of proxy data for the hydrography of the N. Atlantic has suggested 3 modes of operation of the MOC, modern, peak glacial and meltwater pulse modes. The meltwater event mode is the most severe in terms of regional atmospheric temperature drop and cessation of deep meridional overturning In the project we propose to test the hypothesis that rapid climate transitions are always associated with changes in overturning rate in the Nordic Seas. This will make a major contribution to understanding what might happen with increased greenhouse gas levels and global warming.
