Film Summary

The remote Arctic is experiencing the greatest changes in climate of anywhere on the planet. Because small changes send rippling effects through these delicate ecosystems, the predictions of drastic change leave scientists fearing for the future of many Arctic organisms. For millennia local subsistence communities have understood, depended upon and celebrated the annual migration of the Central Arctic Herd of caribou in Alaska. Tens of thousands of caribou repeat the 500+ mile journey through the treacherous Brooks Range, however, affected vegetation, weather and permafrost are jeopardizing safe passage. In 20 years their numbers have dwindled to less than half. Are we seeing their demise? Cloven documents an international team of research scientists as they attempt to unearth whether the future will offer the Central Arctic Herd enough forage to continue making their epic annual migration.
