Vincent Rigby's Canada-US Experts Group Report

webfull — Wed, 11 Feb 2026 18:35:45 +0000

February 11, 2026 | In a new report for the Canada-US Experts Group, Vincent Rigby and Lawrence Herman examine the implications of renewed U.S. expansionist rhetoric for Canada's Arctic sovereignty.

They argue that Donald Trump's annexation threats to Greenland highlight broader strategic risks for Canada, and Washington's longstanding rejection of Canada's claim that the Northwest Passage constitutes internal waters. Rigby and Herman argue that the United States must respond urgently by increasing its Arctic presence and meeting its NATO and NORAD commitments.

January 29, 2026 | In Policy Magazine, Vincent Rigby, writing with Lawrence L. Herman, warns that U.S. President Donald Trump's threat to annex Greenland signals a bigger risk to Canadian sovereignty in the Arctic. They argue that renewed U.S. expansionist rhetoric alongside American rejection of Canada's claim that the Northwest Passage constitutes internal waters raises the prospect of future U.S. military or naval incursions in the region.

January 22, 2026 | Vincent Rigby spoke on KPFA to discuss the implications of U.S. interest in Greenland for Canada. Rigby noted that while the U.S. has a longstanding military presence in Greenland and could, in theory, seize it, such a move would raise serious questions for the North Atlantic Treaty Organization (NATO).

October 16, 2025 | Vincent Rigby spoke at a 91�� roundtable on Arctic sovereignty and security that examined Canada’s northern strategy amid rising geopolitical tensions. He emphasized that national defence cannot be addressed through military means alone, calling for a broader approach grounded in partnership and community well-being. “You can’t have national security without human security,” he said, pointing to the need for sustainable development and trust with Indigenous communities.

March 20, 2025 | Professor Vincent Rigby spoke on the end of arctic exceptionalism on a podcast episode of Center for Strategic & International Studies. Climate change and the reduction in sea ice is opening new shipping routes, and making it easier to tap the arctic’s natural resource wealth, especially critical minerals.

Seabirds & their vulnerability to a warming climate: Q&A with researcher Emily Choy

A study released this month found that as the climate changes in the North, some cold-adapted arctic birds are especially susceptible to heat stress.

Arctic seabirds are less heat tolerant, more vulnerable to climate change

The Arctic is warming at approximately twice the global rate. A new study led by researchers from 91�� finds that cold-adapted Arctic species, like the thick-billed murre, are especially vulnerable to heat stress caused by climate change.

“We discovered that murres have the lowest cooling efficiency ever reported in birds, which means they have an extremely poor ability to dissipate or lose heat,” says lead author Emily Choy, a Postdoctoral Fellow in the Natural Resource Sciences Department at 91��.

In the Arctic, climate change and pollution are the biggest threats to top predators like narwhals. Studying the animals’ tusks reveals that diet and exposure to pollution have shifted over the past half century in response to sea-ice decline. Human emissions have also led to a sharp rise in the presence of mercury in recent years, according to an international team of researchers.

Emily Choy [Post Doctoral Fellow, NRS. Advisor : Kyle Elliott] became hooked on the Arctic when, as a Master’s student, she jumped on a research opportunity to study the effects of manmade contaminants on High Arctic food webs on Devon Island, Nunavut. “When I experienced how out of the world it was and observed the wildlife that are so highly adapted to the Arctic environment, I just fell in love,” says Choy.
