 The analysis of 30 years of global monthly normalized difference vegetation index, NDVI, data revealed that almost half of the land surface exhibit significant seasonal trends. The most common type of trend was an increase in NDVI in the green season, which was balanced out by a decrease in the brown season. This was mainly seen in grasslands and shrublands, as well as in tigers and tundras. No single attribution of cause could be determined for this trend, but it was clear that it was related to climate-related ameliorations of growing conditions.
