  • Wednesday, November 3, 12:00 noon – Blue Carbon: The Role of Estuaries in Combating Climate Change, Online

    Blue Carbon refers to the ability of certain coastal ecosystems – salt marshes, seagrass beds, and mangroves – to capture and store carbon dioxide and other greenhouse gasses from the atmosphere, helping to mitigate the effects of climate change. Coastal ecosystems are more efficient than upland forests at this process of carbon sequestration, but they tend to be smaller and in more densely populated areas. We have already lost many of our coastal ecosystems, and they remain under pressure from human development and from sea level rise. Recent interest in blue carbon is bringing new attention to the importance of maintaining healthy and thriving coastal wetlands, for all the benefits that they provide, including habitat for fisheries and migratory birds, flood protection, and climate mitigation. This Ecological Landscape Alliance online presentation on November 3 at noon will explain how carbon cycles through coastal systems, what makes these environments so efficient at carbon sequestration, and what measures can help to protect and restore coastal ecosystems.

    Speaker Hilary Stevens is the coastal resilience manager at Restore America’s Estuaries. She oversees the Blue Carbon and Living Shorelines programs. She is a geologist and environmental scientist with extensive experience in coastal resource management. Ms. Stevens has worked on coastal issues and climate change adaptation around the U.S. and globally, with an emphasis on using best-available science to address community needs and improve resource management. She has a particular affinity for island communities, stemming from her time working in Saipan, Northern Mariana Islands, and as a Peace Corps volunteer in the Philippines. She holds a master’s degree from the Yale School of Forestry and Environmental Studies and a bachelor’s degree from Wesleyan University.

  • Wednesday, November 9, 6:00 pm – How Much Can Trees and Forests Slow Global Warming?

    Much research and debate in the scientific community is devoted to the question the impact forests have on in the capture or sequestration of carbon dioxide, the primary gas that causes the climate-warming “greenhouse effect.” Are more forests the key to slowing the rate of rising global temperatures or is it too optimistic to think they can capture enough of the world’s CO2 emissions to solve the problem? Hear two of Harvard’s most active climate researchers tackle this question from different perspectives, atmospheric chemist Steven Wofsy and forest ecologist Andrew Richardson, on Wednesday, November 9, beginning at 6 pm. Free and open to the public, Geological Lecture Hall, 24 Oxford Street. Part of the Challenges and Choices lecture series. For more information, visit www.hmnh.harvard.edu.
