Arctic warming is causing an expansion of deciduous shrubs in the Arctic tundra biome. By modifying albedo, shrubs affect the temperature of the atmosphere, snowpack and permafrost, potentially increasing permafrost thawing and snow melting, and forming a powerful feedback to global warming. The mos...
