The Canadian spy service warns that climate change poses a deep and persistent threat to national security and prosperity, including the possible loss of parts of British Columbia and the Atlantic provinces to sea level rise. A newly released analysis by the Canadian Security Intelligence Service also predicts a rise in ideologically motivated violent extremism from people who want to accelerate solutions to climate change and those more concerned with preserving their current way of life. The brief was drafted in April 2021, but was only recently released to the Canadian press in response to an access to information request filed in October of that year. CSIS highlights several concerns posed by global warming, from looming dangers to the Arctic, coastal and border security, to severe pressures on food and water supplies. A senior CSIS official signaled the service's interest in monitoring the consequences of climate change at a security conference in November 2021, saying the agency must continue to anticipate the "next threat" to support other government actors. "It's not surprising that security agencies are starting to pay more attention to this because it's clear that climate change is starting to bite," said Simon Dalby, a professor emeritus at Wilfrid Laurier University who studies climate effects, environmental security and geopolitics. The CSIS brief is a more sophisticated framing of climate change as a security issue "than we see in most other federal government policies and documents," said Will Greaves, a political scientist at the University of Victoria.
