A major focus of the federal government’s defence policy update is the need to develop quantum-based defence technology that will help Canada address two big threats: the Arctic and cyber security.
The 20-year timeline of Canada’s new defence policy, and the fact that several proposed investments will “be explored,” raises serious questions about its commitment to pull its weight in NATO.
Climate and environmental insecurity is set to grow in severity as the world warms. The upcoming launch of a new NATO climate change and security centre in Montréal aims to address these concerns.
Canada, and particularly the Canadian Arctic, is warming at a considerably higher rate than the global average. The consequences for Canada could be devastating.
Researchers have made a fascinating observation: a polar bear used a diving hunting technique, never before reported, to capture large moulting snow geese.
The early heat melted snow and warmed rivers, heating up the land and downstream ocean areas. The effects harmed salmon fisheries, melted sea ice and fueled widespread fires.
The accumulation of synthetic pollutants found in the blubber of killer whales is impacting the marine mammals’ health. Urgent action is needed to tackle the issue.
Large stretches of the Arctic are carbon-rich peat bogs. As the region warms and dries, lightning strikes can spark underground fires that can burn for years.
To fully understand the extent of climate-related dangers the Arctic – and our planet – is facing, we must focus on organisms too small to be seen with the naked eye.
