Thursday, February 23, 1 pm US EST/10 am US PST/6 pm UTC. Presented by: Katie Lebling of World Resources Institute. Description: The ocean is already a major carbon sink and plays a crucial role in global climate regulation. At the same time, as the urgency of the climate crisis worsens, attention is turning to the ocean for its potential to play an even bigger role in addressing this. Part of this could be through ocean-based carbon dioxide removal (CDR), which is receiving increasing attention and investment. However, most approaches are still in the early stages of development, have a high degree of uncertainty about their efficacy and impacts, and lack sufficient governance to ensure responsible deployment.
This webinar will present key findings from a recent WRI report on ocean CDR, including a summary of prominent ocean CDR approaches (coastal blue carbon restoration, seaweed cultivation, ocean fertilization, alkalinity enhancement, electrochemical approaches, artificial upwelling, and artificial downwelling), an overview of the governance landscape, and recommendations for a pathway forward that balances the urgent need for emission reductions with a precautionary approach to avoid further harm to ocean systems, ecosystems, and coastal communities.
Thursday, March 2, 1 pm US EST/10 am US PST/6 pm UTC. Presented by: Ben Halpern of the University of California, Santa Barbara. Description: Feeding humanity puts enormous environmental pressure on our planet. These pressures are unequally distributed, yet we have piecemeal knowledge of how they accumulate across marine, freshwater, and terrestrial systems. This webinar will present global geospatial analyses detailing greenhouse gas emissions, freshwater use, habitat disturbance and nutrient pollution generated by 99% of total reported production of aquatic and terrestrial foods in 2017. These results have also been rescaled and combined to map the estimated cumulative pressure, or ‘footprint’, of food production. On land, five countries contribute nearly half of food’s cumulative footprint, and just 10% of the planet contributes 93% of this footprint. The pressures that drive these footprints vary substantially by food and country. Importantly, the cumulative pressure per unit of food production (efficiency) varies spatially for each food type such that rankings of foods by efficiency differ sharply among countries. These disparities provide the foundation for efforts to steer consumption towards lower-impact foods and ultimately the system-wide restructuring essential for sustainably feeding humanity.
Wednesday, March 15, 1 pm US EDT/10 am US PDT/5 pm UTC. Presented by: Ajay Sawant of Apollo College of Veterinary Medicine, Julia Lara Navarrete of Autonomous University of Baja California, Rebecca Allen of Western Washington University, Serag Heiba of Chinese University of Hong Kong, Summer Snell of Brookes University, and Frances Lang of The Ocean Foundation. Description: With support from The Ocean Foundation and National Geographic Society, a group of young writers between the ages of 18-25 are creating a “youth ocean action toolkit” focused on the ocean literacy principles and marine protected areas (MPAs). This toolkit – written by youth for youth – provides community examples of how youth can take action to conserve their ocean; demonstrates the benefit of MPAs for ocean conservation; includes links to resources and multimedia content; and features a strong social media component. The toolkit will be available this summer in English and Spanish. This webinar featuring some of the toolkit’s youth authors will provide an overview of the content and techniques to engage and empower young people around the world.
