| Description: |
For about a decade now it has been recognized that the Arctic system is undergoing unprecedented change. This change is an amplified response to global change and expresses itself across all domains: physical, biogeochemical, ecological and human. Rapid and urgent response from the scientific community is required to determine the rate of change, to understand its causes and for future projection, as well as for an optimal design of response strategies, including mitigation and adaptation. This session presents results from integrated Arctic Environmental Change programs as well as from individual projects addressing this challenge. Topics deal with observing, understanding, and responding to Arctic Environmental Change across physical, biogeochemical, and human domains. The goal is to highlight the need for close collaboration across domains in research and the approaches required to describe and understand the nature of Arctic Environmental Change, as well as to project future changes. Contributions with emphasis on observing system design, novel utilization of data from the Arctic Observing System, results from synthesis/modeling studies of Arctic System change, and results from the International Polar Year are especially encouraged. |
