On Saturday 26 May, ANU School of History's Professor Tom Griffiths will share the stage with some of Australia's most innovative thinkers at TEDx Sydney.

Tom's presentation, 'One degree, one thousand years: An environmental history', will take participants on a journey into the ice, especially the ice of Antarctica, where ice cores now reveal almost a million years of climate history.

Over the last thousand years, human society has been challenged and transformed by natural fluctuations in average global temperature of less than 1 degree Celsius, so what will prospective rises of 2, 3 or even 4 degrees mean for civilisation?  The challenge of environmental history is to link deep, evolutionary time with our experience of daily, social time, and to work audaciously across time and space and species.

Tom's presentation will be streamed live from 9am on Saturday 26 May.
