Life in the Arctic: Climate Change and Contaminants Accumulation

This lecture explores the impact of climate change and contaminants accumulation in the Arctic region. It covers topics such as the convergence of atmospheric and marine currents, bioaccumulation and biomagnification in the food chain, sea-ice retreat consequences on wildlife, and the phenomenon of Arctic greening or browning. The presentation also discusses the effects of increased rain-on-snow events in the polar night, which reduce vegetation availability and lead to population die-offs. Overall, the lecture highlights how climate change and pollution have a magnified impact on the fragile Arctic ecosystem.
