SUMMARY:The relative importance of Antarctic sea-ice loss within the respo
 nse to greenhouse warming - Stephanie Hay (University of Exeter)

DESCRIPTION:The response to Antarctic sea-ice loss is examined in comparis
 on to the response to Arctic sea-ice loss and within the context of genera
 l greenhouse warming. Sea-ice loss responses are found to be linear with r
 espect to the degree of imposed perturbation and additive when perturbatio
 ns are applied in hemispheres separately and concurrently. Globally\, and 
 in the tropical Pacific in particular\, Antarctic sea-ice loss plays a rel
 atively larger role than Arctic sea-ice loss in both the atmosphere and th
 e ocean. Multi-parameter pattern scaling reveals the aspects of the respon
 se that are directly related to Antarctic change\, such as an equatorward 
 intensification of tropical precipitation in the Northern Hemisphere\, and
  those that are modified via the induced changes in the tropics and Arctic
 \, such as Northern Hemisphere temperature change.
