Task Team 4: Climate Sensitivity to AMOC: Climate/Ecosystem Impacts

The task team is charged with better understanding the links between the AMOC and North Atlantic SST and teleconnections with climate variability elsewhere.

Near-term priorities

  • Identify the mechanisms by which AMOC variability, imprinted on SST and/or the cryosphere, affects local and remote atmospheric patterns and phenomena.
  • Assess AMOC impacts on the cryosphere, particularly Arctic sea ice and the Greenland Ice Sheet.
  • Assess AMOC impacts on global and regional sea level.
  • Improve understanding of how AMOC variability affects ocean-atmosphere exchanges of carbon, biogeochemical cycles, and marine ecosystems.

Long-term priority

  • The long-term goal of Task Team 4 is to understand how AMOC variability affects other components of the Earth system – its climate, hydrologic cycle, atmospheric circulation, coupled phenomena (e.g., ENSO, monsoons), cryosphere, sea level, marine and terrestrial ecosystems, biogeochemical cycles, and carbon budgets – both locally and remotely.
