Noon seminar - Climate change in the fast lane: Science, data & communication of Arctic sea ice obsv

Arctic sea ice is one of most dramatic indicators of change in the global climate system over the past three decades, with reductions in summer ice extent of over 30% and coinciding thinning of the ice cover. It appears that the Arctic will likely experience near ice-free conditions during summer within the next 30 to 40 years. The impacts of such a change will be widespread, both within and outside of the Arctic, and will affect climate, wildlife, and human activities. As a result, sea ice data has been widely used by scientists, policymakers, military planners, educators, media, and the general public. This talk will review historical and recent observations of sea ice change, evolving issues with sea ice data, and lessons learned from interacting with the public about NSIDC’s sea ice data.
