Eurasian Arctic greening reveals teleconnections and the potential for structurally novel ecosystems

Increasing shrub cover on Arctic tundra is linked to climate warming, which is partially amplified by sea ice feedbacks, but the nature of these interactions remains poorly understood. Now research indicates that tundra plant productivity in late spring relates to sea-ice-driven temperature amplification but that the growing season peak is more closely associated with persistent large-scale atmospheric circulation patterns.
