7. White Arctic, Blue Arctic

The region of most profound climate change is the poles. The ice-covered Arctic Ocean – the white Arctic - and the region surrounding it are already changing remarkably and climatologists predict that we may see an ice-free Arctic Ocean during the summer in a few decades -- the blue Arctic. While climatologists are alarmed by this possibility, others seek opportunities for use of resources and as a transportation route. 
          What does science tell us about the future of the Arctic? 
          How would issues about the future – white or blue – be resolved?
          What models and monitoring data will be required to support an emerging management regime that would allow for sustainable use of the Arctic?
          How can use of the Arctic and its resources be managed in the face of these possibilities?

Consequences of a Warming of the Arctic on the World Order and Perspectives that lead towards Global Solutions Last Updated on 2010-12-22 08:07:27 Robert W. Corell  *for figures and images, see attached word document Foundational Perspectives: Earth's climate is changing, with the global temperature now rising at a rate unprecedented in the experience of modern human society. The strength of the trends and the patterns of change that have emerged in recent decades indicate that human influences, resulting primarily from increased emissions of carbon dioxide from fossil fuels and other greenhouse gases, have now become the dominant factor. These climate changes are being experienced particularly intensely in the Arctic. Arctic average temperature has risen at twice the rate as the rest of the world for the past few decades. Widespread melting of glaciers and substantial losses of sea ice (Figure 1) in the Arctic regions and rising permafrost temperatures present additional evidence of strong warming. The changes in...
