Temperatures there are rising at twice the global rate, sparking an array of changes unlike anything in recorded history. One of the most striking examples is the region's sea ice, whose dramatic decline over the past decade has led to forecasts of an ice-free Arctic Ocean as early as the 2030s. .

We generated phenologically-modeled time series of annual maximum summer Normalized Difference Vegetation Index (NDVImax) from 1985 to 2016 for 50,000 sampling sites across the Arctic tundra biome using cross-calibrated surface reflectance measured by Landsat 5, 7, and 8. .
