Keynote lectures

Prof. dr. Detlef van Vuuren
Detlef van Vuuren is professor in Integrated Assessment of Global Environmental Change at the Faculty of Geosciences, Utrecht University and senior researcher at PBL Netherlands Environmental Assessment Agency leading the IMAGE integrated assessment modeling team. He participates in various research organizations in the field of environmental research and has been active in numerous research projects and assessments. He had a coordinating role in the development of the Representative Concentration Pathways (RCPs) and Shared Socio-economic Pathways (SSPs) now used in the IPCC’s assessments. (Source: UU intranet)

dr. Bärbel Hönisch
Bärbel Hönisch is Associate Professor at the department of Earth and Environmental Sciences, Columbia University. Her research focusses on understanding the role of the ocean and in particular the role of marine carbonate chemistry in global climate change. As she was originally trained as a (marine) biologist, her way of approaching paleoceanographic questions often includes a biological component. Coretop observations on sub-fossil specimens and culture experiments with living marine calcifiers form an important aspect of her research and helps her to better understand the proxies used for paleoreconstructions. She is specifically interested in estimating past seawater-pH and atmospheric pCO2. (Source:
