Professor Andy Baker's Public Lecture

Date: 1 December 2009

Time: 8.00pm

Venue: The Senate Lounge, University College

Title: Caves and Climate Variability: the potential effects of future climate change in Ethiopia

Ten years ago Andy Baker was first given the opportunity to work in Ethiopia. With a history of periodic drought and famine, he decided to investigate whether cave stalagmites could provide long records of rainfall variability in the country.   In this lecture he will reveal what he has learnt so far about climate variability in the region. To get to that point, the complex routes by which rain water reaches a stalagmite will be discussed, and biogeochemical markers which are transported by the water and provide evidence of environmental and climate change will be interpreted.  His research group's latest results will be presented and discussed in the context of understanding rainfall variability and the potential effects of future climate change in the region.
