• Charles Bullard Lectures | Megafires in the Far North: From Global Impacts to Local Solutions (Cambridge)

    Biological Lecture Hall (1080), 16 Divinity Ave, Cambridge

    Climate warming is causing wildfire activity to increase in boreal forests and arctic tundra of the Far North. Fires are burning more deeply into thick organic soils and destabilizing permafrost, releasing carbon to the atmosphere that has been stored for centuries to millennia. At a global scale, these wildfires are impacting people through production of smoke and the release of greenhouse gasses that contribute to climate warming. At a local scale, increasing wildfire activity is creating new risks and vulnerabilities for local people that depend upon these ecosystems for their wellbeing. In this talk, Dr. Mack will discuss the ecological mechanisms that drive this positive feedback between wildfire and climate warming. She will explore how ecosystems and local human communities in Alaska are responding to increasing wildfire, and how we can employ emerging ideas in forest and fire management to reduce fire activity and promote human wellbeing.

    Dr. Mack will present two public lectures as part of Harvard’s annual Charles Bullard Lecture Series— in Cambridge on the evening of October 8, and in Petersham (and on Zoom) on the morning of October 9.

  • OEB Seminar Series: Randi Rotjan

    Biological Lecture Hall (1080), 16 Divinity Ave, Cambridge

    Randi Rotjan , Associate Professor of Biology , Tufts University | Protecting Global Oceans in the Anthropocene

    Abstract: The oceans are 71% of our planet, and yet are still largely unexplored, especially in the deep and open oceans. New species are discovered on almost every deep-sea dive, and even with increased exploration efforts, we are still discovering massive underwater mountains, canyons, and other features. Yet, even with so much unknown, decisions cannot wait for discovery. In an era of global change, biological communities in even the most remote parts of our planet are feeling the impact of human societies and are vulnerable to depletion or extinction. To combat this, global targets for protection have set a goal of protecting 30% of oceans by 2030. This seminar will unpack the science behind large scale marine conservation, and discuss how to explore the unexplored, and how to protect the unprotected.
