Impact of Climate Change on Physical and Biogeochemical Processes in the Hydrologic Cycle: Challenges and Perspectives.

This special issue “Impact of climate change on physical and biogeochemical processes in the hydrologic cycle” presents a collection of articles on interactions of climatic drivers and hydro-biogeochemical responses as well as the role of biogeochemical processes in controls and feedbacks with regard to climate change impact. While the in-depth disciplinary studies are critically needed as presented in this issue, we also strongly believe that systems approach transcending disciplinary boundaries is needed to address the climate change in integrated natural and human systems.
