Arctic Greening Driven by Warmer Temperatures

As Arctic summers warm, Earth's northern landscapes are changing. Using Landsat satellite data to track global tundra ecosystems over decades, a new study found the region has become greener, as warmer air and soil temperatures lead to increased plant growth.

Landsat data can be used to determine how much actively growing vegetation is on the ground – greening can represent plants growing more, becoming denser, and/or shrubs encroaching on typical tundra grasses and moss. Between 1985 and 2016, about 38% of the tundra sites across Alaska, Canada, and western Eurasia showed greening. Only 3% showed the opposite browning effect, which would mean fewer actively growing plants.
