Upcoming Webinar
Climate Conversations: Ocean Carbon Dioxide Removal
Thursday, January 20, 2022 | 3-4 pm ET

|
Join us for a conversation about the social aspects and potential role of ocean carbon dioxide removal in addressing climate change.
To combat climate change, in addition to reducing emissions, we will also need to remove greenhouse gases from the atmosphere. Ocean CDR (ocean carbon dioxide removal) is a set of strategies to sequester carbon dioxide in ocean waters. Sarah Cooley (Ocean Conservancy) will moderate a conversation between Holly Buck (University at Buffalo)and Nick Pidgeon (Cardiff University) about social acceptance, environmental governance, and other issues around ocean CDR strategies. The webinar will include a discussion of the new National Academies report, A Research Strategy for Ocean-based Carbon Dioxide Removal and Sequestration.
The conversation will be webcast on the Climate Conversations: Ocean Carbon Dioxide Removal webpage on Thursday, January 20, 2022, from 3-4 pm ET. Closed captioning will be provided. The conversation will include questions from the audience and will be recorded and available to view on the page after the event.
Climate Conversations: Pathways to Action is a monthly webinar series from the National Academies of Sciences, Engineering, and Medicine that aims to convene high-level, cross-cutting, nonpartisan conversations about issues relevant to national policy action on climate change.

As of 2021, atmospheric carbon dioxide levels have reached historically unprecedented levels, higher than at any time in the past 800,000 years. Worldwide efforts to reduce emissions by creating a more efficient, carbon-free energy system may not be enough to stabilize the climate and avoid the worst impacts of climate change. Carbon dioxide removal (CDR) strategies, which remove and sequester carbon from the atmosphere, likely will be needed to meet global climate goals. The ocean, ...

The world is transforming its energy system from one dominated by fossil fuel combustion to one with net-zero emissions of carbon dioxide (CO2), the primary anthropogenic greenhouse gas. This energy transition is critical to mitigating climate change, protecting human health, and revitalizing the U.S. economy. To help policymakers, businesses, communities, and the public better understand what a net-zero transition would mean for the United States, the National Academies of Sciences, ...

To achieve goals for climate and economic growth, "negative emissions technologies" (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change. Unlike carbon capture and storage technologies that remove carbon dioxide emissions directly from large point sources such as coal power plants, NETs remove carbon dioxide directly from the atmosphere or enhance natural carbon sinks. Storing the carbon dioxide from NETs has the same ...

Climate change is creating impacts that are widespread and severe for individuals, communities, economies, and ecosystems around the world. While efforts to reduce emissions and adapt to climate impacts are the first line of defense, researchers are exploring other options to reduce warming. Solar geoengineering strategies are designed to cool Earth either by adding small reflective particles to the upper atmosphere, by increasing reflective cloud cover in the lower atmosphere, or by ...

While progress has been made in the development of decarbonization technologies, much work remains in scale-up and deployment. For decarbonization technologies to reach meaningful scale, real-world constraints, societal, economic, and political, must be considered.
To identify the primary challenges and opportunities to deploying decarbonization technologies at scale across major sectors of the U.S. economy, the Board on Energy and Environmental Systems of the National Academies of ...

The signals are everywhere that our planet is experiencing significant climate change. It is clear that we need to reduce the emissions of carbon dioxide and other greenhouse gases from our atmosphere if we want to avoid greatly increased risk of damage from climate change. Aggressively pursuing a program of emissions abatement or mitigation will show results over a timescale of many decades. How do we actively remove carbon dioxide from the atmosphere to make a bigger difference more ...

Coral reef declines have been recorded for all major tropical ocean basins since the 1980s, averaging approximately 30-50% reductions in reef cover globally. These losses are a result of numerous problems, including habitat destruction, pollution, overfishing, disease, and climate change. Greenhouse gas emissions and the associated increases in ocean temperature and carbon dioxide (CO2) concentrations have been implicated in increased reports of coral bleaching, disease outbreaks, and ocean ...
