Jul 21, 2026 Mario Acquarone, an Arctic policy specialist; David Hik, a polar ecologist; Srdan Dobricic, an atmospheric scientist; and Stefania Gilardoni, an aerosol researcher, explore black carbon’s global reach. They discuss shifting Arctic transport, community monitoring, wildfire smoke, uncertain emissions data, and how soot is darkening Andean glaciers. The conversation also examines turning complex science into practical policy.

Episode notes
Atmospheric Patterns Aim Soot At The Ice Edge
- North Atlantic oscillation changes and Scandinavian blocking can shift black carbon onto Arctic sea ice.
- Scandinavian blocking, linked partly to tropical Pacific disturbances, coincides with sea-ice loss and greater deposition near the ice edge.
Cambridge Bay Maps Its Own Pollution Sources
- Cambridge Bay relies heavily on diesel, marine transport, and burning waste, creating several local particulate sources.
- Polar Knowledge Canada began by asking residents which locations and exposures mattered most to them.
Arctic Communities Now See Southern Wildfire Smoke
- Sensors in Cambridge Bay found ordinary vehicle and heating emissions, plus dramatic summer spikes from southern wildfires.
- Hik illustrated the change with photographs of his house on a clear day and engulfed in smoke.
