Seasonal biological carryover dominates northern vegetation growth

Abstract The state of ecosystems is influenced strongly by their past, and describing this carryover effect important to accurately forecast future behaviors. However, the strength persistence on ecosystem dynamics in comparison that simultaneous environmental drivers are still poorly understood. Here, we show vegetation growth (VGC), defined as present states subsequent growth, exerts strong positive impacts seasonal over Northern Hemisphere. In particular, VGC early growing-season even stronger than past co-occurring climate determining peak-to-late season primary contributor recently observed annual greening trend. persists into year but not further. Current process-based models greatly underestimate effect, may therefore CO 2 sequestration potential northern under warming.
