Since its birth during the Cold War, Canada's spy agency has occupied itself with three primary threats: terrorism, espionage and foreign interference in domestic politics and business. Now, the Canadian Security Intelligence Service is pointing to a disruptive new player on the field: climate change. CSIS says it's trying to get a handle on how climate change will disrupt national security. It has even acknowledged that effort publicly — something intelligence agencies rarely do. "This is something that will absolutely have profound impacts on Canadians and it will have impacts on our national security. I think it's important that we are going to be in that space," Tricia Geddes, deputy director for policy at CSIS, told an intelligence conference last month.
