Focus on recent, present and future Arctic and boreal productivity and biomass changes
Abstract The reduction of cold temperature constraints on photosynthesis in recent decades has led to extended growing seasons and increased plant productivity (greening) in significant parts of Polar, Arctic and Boreal regions, here called northern lands. However, most territories within these regi...
