School of Geography Distinguished Visitor Lecture 2015

Dr Thomas M. Cronin, US Geological Survey

The School is delighted to welcome Dr Thomas M. Cronin from the US Geological Survey as its Distinguished Visitor for 2015.

Dr Cronin is a world-leading research geologist and author of Paleoclimates: A Context for Climate Change (Columbia University Press, 2010).

This lecture will look at our current understanding of Arctic Ocean sea ice, temperature, and climatic history, and discuss how it can be used as a framework for understanding future man-made changes to the climate in the Arctic.

Sea ice history reconstructed from fossils preserved in Arctic Ocean sediments is revealing its significant sensitivity to relatively small-scale changes in the climate. New studies reveal substantial variations in sea ice cover during the last several million years. For example, periods of seasonally sea-ice free conditions in at least some regions of the Arctic include the early Holocene (about 7,000-10,000 years ago), the last interglacial period (~125,000 years ago), Marine Isotope Stage 11 (~400,000 years ago) and the middle Pliocene (~3 million years ago). Arctic sea ice, past, present and future will be the focus of this public lecture at QMUL.

Attendance is free and the lecture will be followed by a wine reception.
