Climate extremes and the carbon cycle
Markus Reichstein,Michael Bahn,Philippe Ciais,Dorothea Frank,Miguel D. Mahecha,Sonia I. Seneviratne,Jakob Zscheischler,Jakob Zscheischler,Christian Beer,Christian Beer,Nina Buchmann,David Frank,Dario Papale,Anja Rammig,Pete Smith,Kirsten Thonicke,Marijn van der Velde,Sara Vicca,Ariane Walz,Martin Wattenbach +19 more
TL;DR: The mechanisms and impacts of climate extremes on the terrestrial carbon cycle are explored, and a pathway to improve the understanding of present and future impacts ofClimate extremes onThe terrestrial carbon budget is proposed.
Journal ArticleDOI
Human-induced nitrogen–phosphorus imbalances alter natural and managed ecosystems across the globe
Josep Peñuelas,Benjamin Poulter,Jordi Sardans,Philippe Ciais,Marijn van der Velde,Laurent Bopp,Olivier Boucher,Yves Goddéris,Philippe Hinsinger,Joan Llusià,Elise Nardin,Sara Vicca,Michael Obersteiner,Ivan A. Janssens +13 more
TL;DR: It is shown that limited phosphorus and nitrogen availability are likely to jointly reduce future carbon storage by natural ecosystems during this century and if phosphorus fertilizers cannot be made increasingly accessible, the crop yields projections of the Millennium Ecosystem Assessment imply an increase of the nutrient deficit in developing regions.
Journal ArticleDOI
Effects of climate extremes on the terrestrial carbon cycle: concepts, processes and potential future impacts
Dorothe A. Frank,Markus Reichstein,Michael Bahn,Kirsten Thonicke,David Frank,Miguel D. Mahecha,Pete Smith,Marijn van der Velde,Sara Vicca,Flurin Babst,Flurin Babst,Christian Beer,Christian Beer,Nina Buchmann,Josep G. Canadell,Philippe Ciais,Wolfgang Cramer,Andreas Ibrom,Franco Miglietta,Ben Poulter,Anja Rammig,Anja Rammig,Sonia I. Seneviratne,Ariane Walz,Martin Wattenbach,Miguel A. Zavala,Jakob Zscheischler +26 more
TL;DR: It is found that ecosystem responses can exceed the duration of the climate impacts via lagged effects on the carbon cycle, and forests are expected to exhibit the largest net effect of extremes due to their large carbon pools and fluxes, potentially large indirect and lagged impacts, and long recovery time to regain previous stocks.

TL;DR: The first ever global field size map was produced at the same resolution as the IIASA-IFPRI cropland map based on interpolation of field size data collected via a Geo-Wiki crowdsourcing campaign.
Journal ArticleDOI
Geo-Wiki: An online platform for improving global land cover
Steffen Fritz,Ian McCallum,Christian Schill,Christoph Perger,Linda See,Dmitry Schepaschenko,Marijn van der Velde,Florian Kraxner,Michael Obersteiner +8 more
TL;DR: The components that comprise Geo-Wiki are outlined and how they are integrated in the architectural design, in particular the need to add a mechanism for feedback and interaction as part of community building, and theneed to address issues of data quality.
