ARCUSThe increasing pace and scale of observed environmental change in the Arctic and around the globe raises an important question: Have we reached major tipping points in the arctic system? The interconnectedness of the Arctic is demonstrated when a single change sends ripple effects throughout the marine, terrestrial, atmospheric, socioeconomic, and global systems. Participants at the Arctic Forum will discuss how such changes may be "tipping points" that represent new, unknown, and potentially irreversible vanguards of arctic and global change.

The 2008 Arctic Forum is being co-chaired by Martin Miles, Environmental Systems Analysis Research Center in Boulder, Colorado, and Craig Fleener, Gwich'in Council International.

The meeting will be webcast live on Wednesday, 14 May beginning at 10:00 a.m. EDT, and Thursday, 15 May beginning at 8:30 a.m. All talks will be video-streamed with an online bulletin board so that those unable to attend in person can participate virtually.
