Abstract
The global greening trend, marked by significant increases in vegetation cover across ecoregions, has attracted widespread attention.
…
Findings from the TST workflow (Fig. 2) provide robust quantitative evidence of widespread global greening, with a significant portion of Earth’s terrestrial land surface showing measurable increases in vegetation cover over the past four decades. The predominance of greening trends, especially in regions with NDVI values above 0.15, suggests a general increase in vegetation productivity in many areas. This could be attributed to CO₂ fertilisation, climate change, and land use changes, as indicated by other investigations (Chen et al., 2024; Piao et al., 2019; Zhu et al., 2016). Although vegetation greening has been reported on all continents, it is particularly pronounced in Eurasia, including regions of Europe and China (Chen et al., 2019a).

Conclusions
Applying a new proposed workflow methodology (True Significant Trends, TST) we reveal a striking global greening trend, with a significant portion of the Earth’s terrestrial land surface showing increases in vegetation cover over the past four decades, particularly in Eurasia.
