Net carbon uptake has increased through warming-induced changes in temperate forest phenology

The timing of phenological events exerts a strong control over ecosystem function and leads to multiple feedbacks to the climate system. Phenology is inherently sensitive to temperature (although the exact sensitivity is disputed) and recent warming is reported to have led to earlier spring, later autumn and increased vegetation activity. …
