In the struggle to cope with climate change, what lessons can be learnt from Earth's long history? Two leading geologists explain the important insights science is now able to give us about dramatic changes in Earth's distant past, and the delicate balance that ensures our planet is 'not too hot, not too cold', but 'just right' to sustain life.
Dr Jan Zalasiewicz is Senior Lecturer in Geology at Leicester University. A field geologist, palaeontologist, and stratigrapher, he teaches various aspects of geology and Earth history to undergraduate and postgraduate students, and is a researcher into fossil ecosystems and environments across over half a billion years of geological time. He is the author of The Earth After Us and The Planet in a Pebble, both published by OUP. He has published over a hundred papers in scientific journals. Dr Mark Williams is Reader in Geology at Leicester University and a former scientist with the British Antarctic Survey. He has a strong interest in how the fossil record reflects changes in Earth's climate through time. He teaches many aspects of geology but especially climate change over geological timescales. He has published over a hundred papers in scientific journals.
