In 2010, Dr Stephen Leonard embarked on a year-long trip to live with the Inughuit of north-west Greenland who live in the northernmost permanently inhabited settlement in the world. His aim was to record the marginal language, stories and songs of these communities - all of which are potentially threatened by a range of factors, one of which is climate change. Dr Leonard lived as a member of those communities, travelled on hunts, and recorded and filmed as he went. Here is lecture he gave at Trinity Hall, Cambridge, in October 2011.

Dr Leonard's research was funded by the British Academy and the World Oral Literature Project
