Description

Lower levels of ice and snow cover may cause changes in cargo traffic, travel and tourism, oil exploration and production, fishing and agriculture. The society does, however, have a potential to influence Arctic warming, either through targeted emission control or geoengineering. But how important are the different feedback mechanisms including the ice-albedo feedback?

The ongoing Arctic climate change and cryosphere are interlinked through radiative forcing, arctic warming, changes in the cryosphere, society and human activities, and feedbacks in the climate system. Traditionally, the enhanced warming of Arctic areas has been explained by the so-called ice-albedo feedback.

The NCoE CRAICC will expand this thinking and include the roles of society and associated human activities as part of the interactions and feedback mechanisms acting on the Arctic climate system.

The NCoE CRAICC will focus on the role played by short-lived pollutants and aerosol-cloud interactions and their linkages with cryospheric changes, as:

  • their role in Arctic warming in potentially very large, yet poorly quantified
  • their emissions are expected to change considerably as a result of future warming and associated changes in human activities
  • and they might provide an additional mitigation pathway for future Arctic warming.
