Lawrence Martin in a Canadian singer and politician now heading a maritime conservation council for the indigenous communities around Hudson Bay. Megan Sheremata is a Ph.D. candidate at the University of Toronto who studies the environment of the eastern shore of Hudson Bay. We discuss the various technical possibilities for cooling that body of water with Professor Stephen Salter and Paul Beckwith, a climatologist. One method would be cloud brightening; another might be thinning the cirrus clouds of the region, which tend to warm the planet. That would allow heat from the planet to escape. A third possibility might be to thicken the winter ice by spraying the surface with warmer water from below. All have potentially negative consequences as well as good ones.
