Disentangling the drivers of Arctic greening across scales

The “greening of the Arctic” is among the world’s most significant large-scale ecological responses to global climate change. In recent decades, the Arctic has warmed at twice the rate of the rest of the planet and satellite-derived vegetation indices have indicated widespread increases in productivity at high latitudes. Advancing plant phenology, increasing biomass and trait change are all associated with warming trends. Yet, the direct versus indirect drivers of tundra vegetation change and how well local-scale measurements match remotely-sensed observations remain unclear. I will summarize the work of my research group, Team Shrub, to capture the landscape context of long-term ecological monitoring and to disentangle the complexity in 
remotely-sensed greening signals. Using cross-site data synthesis and drone-based remote sensing, we are working to better understand how ecological communities are respond to global change at the cold extremes of our planet.
