With global climate change, linking vegetation phenology with net ecosystem productivity (NEP) is crucial for assessing carbon storage capacity and predicting terrestrial changes. However, there have been few studies investigating the relationship between NEP in middle high latitudes of Northern Hemisphere. This study comprehensively analyzed phenological changes their drivers using satellite data. It also investigated spatial distribution further sensitivity to phenology. The results indicated that average land surface (LSP) was dominated by a monotonic trend area. LSP derived from different products retrieval methods exhibited relatively consistent responses climate.

Variations in water availability seasonality significantly impact society and ecosystems. While many studies have focused on mean or extreme precipitation, the response of seasonality, influencing yearly distribution beyond individual extremes, to human-induced climate change remains underexplored. Here we examine global regional changes from 1915 2014, quantifying how anthropogenic greenhouse gases aerosols influenced these variations using reanalysis simulations Coupled Model Intercomparison Project Phase 6. Despite large spatiotemporal uncertainties due variability model assumptions, find that amplify while reduce it. Given positive effects surpass aerosols' negative effects, counterbalancing influences led an overall enhancement over past century. This trend is expected continue future as gases-induced warming continues rise aerosol levels decline. Anthropogenic gas emissions amplified 100 years, a continue, according analysis meteorology data simulations.
