About the Event: 

Studying the geographical variability and structure of past climate change is critical for understanding the mechanisms behind external climate forcing and how these are translated into regional environmental adaptability. This becomes even more crucial for regions that are highly susceptible to climate change, such as those bordering hyper arid environments. Sub-tropical Africa underwent millennial-scale latitudinal migrations of the ITCZ, which in turn leaded to enhanced humidity during intervals of insolation maxima. In the current presentation, well-constrained lacustrine sedimentary records from both equatorial and sub-tropical regions (Lake Chala (Kilimanjaro area) and Dead Sea, respectively) are used to provide valuable information on cross-latitudinal climate teleconnections during the last 250 ky. This is especially important for understanding how the environmental and climate conditions related to periods with increased monsoonal activity allowed (or inhibited) early human migration out of Africa.

About the Speaker: 

Nicolas Waldmann

Dr. Nicolas Waldmann is from the Department of Marine Geosciences, University of Haifa. He is a geologist majoring in limnogeology and marine geology, with emphasis of using these sedimentary records for climate change reconstruction and basin processes. He has obtained his MSc from the Hebrew University of Jerusalem (Israel), then a PhD at the University of Geneva (Switzerland) and completed a postdoctoral research at the University of Bergen (Norway). Upon his return to Israel in 2011, he founded the Basin Analysis and Petrophysical laboratory (PetroLab) at the University of Haifa, which currently hosts a group of 4 postdocs, 5 PhD and several MSc students. The research is carried out in several places in the world, including Kenya, Chad, Mali, China, Norway, Malta, Oregon, Chile, and Yemen. Based on academic excellence and achievements, he was awarded with the Krill Prize of the Wolf Foundation in 2013.
