New Study Finds Accelerated Greening Of Earth Since 1982
New remote sensing research (Gutiérrez-Hernández and García, 2025) uses robust statistical methods to eliminate false positives and spurious correlations in establishing vegetation trends in the satellite era
The scientists found that 38 percent of the Earth’s 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 percent of the Earth’s surface experienced statistically significant vegetation trends in the satellite era may overlook crucial factors that produce less accurate, inflated results.
With this new analytical method, the True Significant Trends (TCT) test, the authors have robustly determined there has been a “striking global greening trend”.
“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.”
Specifically, 76.1 to 85.4 percent of statistically significant vegetation trends indicate greening, whereas browning trends account for 14.7 to 23.9 percent.
“Among these significant trends identified using the TST workflow, 76.07 percent indicated greening, while 23.93 percent indicated browning.
Notably, considering areas (pixels) with NDVI values above 0.15, greening accounted for 85.43 percent of the significant trends, with browning making up the remaining 14.57 percent.
These findings strongly validate the ongoing global greening of vegetation.”
In other words, greening trends dominate over browning trends at about 4:1, or 80 percent to 20 percent.
