Episodes in the History of Permafrost
Selected date Saturday May 05
Selected time 3:00 PM  –  5:00 PM

 The thawing of permafrost under conditions of global warming has drawn attention to the fact that permafrost is not at all perma. Where did the idea of permafrost come from? Not many people are aware that the term is a translation of a Russian expression. Exploring the history of permafrost as an idea takes us into the history of the Russian Empire and the Soviet Union. In this intriguing talk environmental historian Pey-Yi Chu, PhD. will highlight episodes from this history, showing how ideas about a natural phenomenon were shaped by Russian colonization, Soviet industrialization, Marxist ideology, and the Cold War.
