With global sea levels rising, and more international support to combat climate change, David Victor of the University of California, San Diego, will deliver a lecture titled "Regulating Soot and Methane in the Arctic: Implications for Health, Climate and International Policies." The lecture will focus on the growing opportunities to create effective global cooperation on climate change through small clubs of countries, which could make it easier to forge and implement deals needed for policy coordination. However, research suggests that Russia — which has downplayed the effects of climate change — is a pivotal player if countries in the Arctic want to reduce methane and soot pollutants. The event begins at 3 p.m. in the Institute at Brown for Environment and Society, Room 015, 85 Waterman St.
