NASA scientists utilized 30 years of Landsat satellite data to track vegetation changes across 4 million square miles of Alaska and Canada. Their findings reveal a significant "greening" trend, with 30% of the area showing increased vegetation, while only 3% experienced "browning."

This pioneering study, the first to provide continent-scale detail alongside local information, underscores the impact of rapid Arctic warming. Elevated temperatures lead to extended growing seasons and altered soils, transforming tundras into shrublands. Future research will investigate local factors influencing these greening patterns and explore forested regions.
