OxTalks is Changing
On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
4th Trapnell Lecture: Revisiting the Green Sahara
Status: This talk is in preparation - details may change
Fluctuations and changes in Africa’s climate are critical to people today and over millennia have had profound impacts on our ancestors. Jessica Tierney, recipient of the 2014 American Geophysical Union Macelwane Medal, uses novel geochemical (leaf wax) techniques to reconstruct past hydrology and climate changes in parts of the continent where other reliable records are limited, and where records of the past are vital for improving predictions of the future. Combining empirical and modelling approaches, this talk sheds new light on the timing, extent and causes of the early Holocene ‘Green Sahara’, and its rapid demise to the extreme arid conditions we are familiar with today.
