Seminar title: Methane and the Shale Gas Revolution; Science, Policy, and PoliticsAbstract: Over the past 20 years, the shale gas revolution in the United States has greatly increased natural gas production and exports of liquefied natural gas (LNG), making the US the largest producer and largest exporter of gas in the world. This has led to increased emissions of methane, a greenhouse gas that is more than 80 times more powerful than CO2 when considered on a 20-year time period after emission. In this talk, I will briefly review and summarize how our understanding of methane emissions has changed over time, starting with the first peer-reviewed paper on the climate impacts of methane from shale gas that I published with my colleagues Tony Ingraffea and Renee Santor just 15 years ago, in April of 2011. I will discuss how methane emissions are considered in the landmark New York climate law, the CLCPA of 2019. And I will present my work on the greenhouse gas footprint of LNG exports from the US, and how this influenced the Biden administration to pause further LNG exports. Throughout, I will give examples of how scientific research has influenced the policies and politics around shale gas and climate.
