Abstract
The warming climate is contributing to increased snow melt and shrub growth in the tundra - both of which are associated with altered land-atmosphere feedbacks. The authors studied the albedo of two shrubs encroaching in the Arctic. Contrary to popular belief that shrub coverage will lower Arctic albedo, shrub-covered land had among the highest albedo at the peak of the growing season. More research is needed to better understand energy budgets in the Arctic in the near future growing seasons.
