Map of Arctic tundra showing 2023 greenness patterns next to a time series of peak satellite greenness over past 40 years

(map) Peak summer "greenness"—a satellite measure of the amount and health of vegetation—was higher than average across the tundra in summer 2023, with especially high values (darkest green) in the North American Arctic. (graph) The peak "greenness" reached each summer in the tundra has increased over time in both NOAA and NASA satellite records.
