Webcast Recap

The Arctic is a sentinel of global warming where scientists predict and have observed the largest warming, melting and change, yet a region with planetary impact.   Join us for a discussion of the Arctic's many changes and their implications: Environmental changes in the form of melting sea ice, greening of the Arctic tundra, migrations of species; Challenges facing indigenous people and how they are responding and coping with this changing world; and how feedbacks in the climate system may mean that the Arctic becomes more than an indicator of climate change and perhaps a source of even more greenhouse gasses.  Our panel will help sort out the science from the speculation, and guide effective decisions for the future.

The “Managing Our Planet” seminar series is developed jointly by George Mason University, the Brazil Institute and the Environmental Change and Security Program. It is based on the premise that the impacts of humanity on the environment (including natural resources) are at a planetary scale, requiring planetary-scale solutions.
