Barry Smit, an emeritus professor in geography, is taking part in a public “think tank” discussion April 6 about how climate change will have affected the world seven years down the road.

Part of the Spur Toronto festival happening this week, Smit’s event will be held at 4 p.m. at the Isabel Bader Theatre, 93 Charles Street West, in Toronto.

Spur Toronto is a national festival of politics, art and ideas aimed at bringing together thinkers and scholars, artists and activists, journalists and entrepreneurs to share ideas worth spurring into action.

Smit will share the stage with Tim Flannery, author of the best-selling book The Weather Makers. Published seven years ago, the book brought the issue of climate change to the fore. Now Smit and Flannery will discuss what the next seven years will hold in terms of climate change, sustainability and evolution.

Their “Sustainability: The World in Seven Years” discussion will be moderated by Paul Kennedy, host and producer of the CBC Radio program Ideas.
