The greening of the Earth\u2019s vegetated areas is \u201cattributed to CO2 fertilization, climate change, and land use changes.\u201d<\/strong><\/h4>\n\n\n\n

New remote sensing research (Guti\u00e9rrez-Hern\u00e1ndez and Garc\u00eda, 2025<\/a><\/strong>) uses robust statistical methods to eliminate false positives and spurious correlations in establishing vegetation trends in the satellite era.<\/p>\n\n\n\n

The scientists find 38% of the Earth\u2019s land surface has undergone statistically significant greening or browning trends over the last 42 years (1982-2023). Conventional methods (i.e., Mann-Kendall test) that had previously found 51% of the Earth\u2019s surface experienced statistically significant vegetation trends in the satellite era may overlook crucial factors that produce less accurate, inflated results.<\/p>\n\n\n\n

With this new analytical method, the True Significant Trends (TCT) test, the authors have robustly determined there has been a \u201cstriking global greening trend\u201d attributed to CO2 fertilization and climate change.<\/p>\n\n\n\n

\u201cApplying a new proposed workflow methodology (True Significant Trends, TST) we reveal a striking global greening trend, with a significant portion of the Earth\u2019s terrestrial land surface showing increases in vegetation cover over the past four decades, particularly in Eurasia.\u201d<\/em><\/p>\n\n\n\n

Specifically, 76.1% to 85.4% of statistically significant vegetation trends indicate greening, whereas browning trends account for 14.7 to 23.9%<\/p>\n\n\n\n

\u201cAmong these significant trends identified using the TST workflow, 76.07% indicated greening, while 23.93% indicated browning. Notably, considering areas (pixels) with NDVI values above 0.15, greening accounted for 85.43% of the significant trends, with browning making up the remaining 14.57%. These findings strongly validate the ongoing global greening of vegetation.\u201d<\/em><\/p>\n\n\n\n

In other words, greening trends dominate over browning trends at a ratio of about 4:1, or 80% to 20%.<\/p>\n\n\n\n
