Told by leading climate scientists, Earth Emergency examines four of the major warming feedback loops threatening our planet: Forests, Permafrost, Albedo and Atmosphere. Picking up where its predecessor, the short film anthology "Climate Emergency: Feedback Loops," left off, "Earth Emergency" paints a more hopeful picture of the future if warnings are heeded and changes are made soon. However, the film warns that if left unchecked, feedback loops amplify the threat of rising temperatures and speed up global warming in ways that many aren't aware of. —Variety Magazine
