Three case studies in greenhouse gas emissions: New insights provided by an expanded atmospheric observing network

Speaker(s)
Professor Scot Miller

Assistant Professor of Environmental Health and Engineering, Johns Hopkins University, Whiting School of Engineering

Location: Math & Science Center (MSC), W201

The global record of greenhouse gas measurements is growing rapidly with the launch of several new satellites and an expansion of ground-based monitoring. This new era of big data is set to transform scientific understanding of greenhouse gas emissions, but the volume of new data creates numerous computational challenges for inverse or emissions models that were originally designed for a small number of ground-based observing stations. The beginning of the talk will focus on new, transformative statistical and mathematical approaches to understand emissions using massive satellite datasets. Then, we will apply these techniques to three different case studies in greenhouse gas emissions. The first case study will focus on carbon dioxide sources and sinks estimated using NASA's OCO-2 satellite. Using this data, we find that most existing biogeochemical models underestimate the seasonal amplitude of the global carbon cycle, and we argue that the impacts of climate change on this aspect of the carbon cycle may be larger than previously believed. The second part of the talk focuses on methane emissions from China, the world's largest emitter of anthropogenic greenhouse gases. We specifically use satellite observations to evaluate the success of China's methane emissions policies. Lastly, we will discuss an often-overlooked greenhouse gas called sulfuryl fluoride, which has surprising and unexpected implications for greenhouse gas emissions targets within the US.

What Are We Mining Now

Speaker(s)
Dionne Searcey

Pulitzer Prize-winning New York Times reporter, Dionne Searcey, discusses the mining of minerals such as cobalt and lithium, which are deemed essential to move away from a fossil fuel economy. Yet the mining of these minerals creates its own forms of environmental destruction. As with ancient gemstones, the people doing the mining are sometimes placed in grave danger, often without choice.

This program is held in conjunction with the Carlos Museum's exhibition Making an Impression: The Art and Craft of Ancient Engraved Gemstones and co-sponsored by Emory Climate Talks.

This event will be offered in a hybrid format - we invite you to attend in person (Ackerman Hall in the Carlos Museum on Emory's campus) OR you may register to attend virtually. If you choose to attend via webinar, please register using the link below.

Only One Earth: An Interfaith Call to Climate Action

Speaker(s)
The Rev. Dr. Gerald Durley, Keynote Speaker

Faith communities play a crucial role in the work for ecological justice. On October 16th 2022, civil and environmental rights leader, the Rev. Dr. Gerald Durley will deliver a keynote address about the intersections between faith, climate, and justice at Science Gallery Atlanta. Rev. Durley is the chair of the National Interfaith Power and Light board and the former Pastor of the historic Providence Missionary Baptist Church of Atlanta, where he served for nearly 25 years. In 2011, Rev. Durley was inducted into the International Civil Rights Walk of Fame for his contributions during the civil rights movement in the 1960s. Rev. Durley’s address will be followed by a panel discussion composed of local interfaith leaders and scientists from Emory University, who will respond to Rev. Durley and explore how concerned citizens of faith can mobilize their communities to address the environmental realities and policies requiring our action in the state of Georgia.

Sunday, October 16, 2022
