Climate extremes cause seasonally contrasting changes in ecosystem productivity
A new study, led by Sebastian Sippel from the Max Planck Institute for Biogeochemistry Jena and co-authored by Matthias Forkel from CLIMERS, found that recent changes in extreme weather conditions cause increased carbon uptake by European ecosystems in spring but carbon loss in summer. The increased carbon uptake by plants in spring can however lower soil moisture levels, and thus can exacerbate the carbon loss during drought events in summer.
