Hi, I'm Drew. Welcome to my boneless, gluten-free, organic website! I am a postdoctoral associate at the Duke University Nicholas School of the Environment and an incoming assistant professor of environmental studies and sciences at Oberlin College; also, I am not a closed, non-orientable, boundary-free manifold. Be aware that this website is very large, and some of it is randomly generated. For the full experience, reload a bunch of times and navigate as follows:
Date: 11 February 2026 at 6:30pm CET
Location: Museum of Natural History, Invalidenstraße 43, 10115 Berlin
As part of the Brecht-Tage festival in Berlin, which this year is focused on Brecht's "Green Revolution", I'll be presenting on the politics of knowledge in Earth system modeling and its relationship with Bertolt Brecht's plays and writings on science and nature. Other presenters include Hans Christian von Herrmann, Sebastian Kirsch, Tom Turnbull, and Patrick Primavesi. This is the second of three events taking place at the museum this evening, running from 5:00pm through 8:00pm CET. Entry is free! More information on the Brecht-Tage 2026 website.
Date: 12 February 2026 at 8:00pm CET
Location: Literature Forum at the Brecht House, Chausseestraße 125, 10115 Berlin, Germany
As part of the Brecht-Tage festival in Berlin, my co-author Troy Vettese and I will be presenting some of our work on the surprising resonances between Bertolt Brecht and Laozi: both figures praise forms of non-action and uselessness. In conversation with Heinrich Detering, we will comment on the implications for climate action. This is the fourth of four events taking place at the Brecht-Haus this evening, running from 4:30pm through 9:30pm CET. More information on the Brecht-Tage 2026 website.
Date: 20 February 2026 at 3:30pm ET
Location: NC State campus (exact location tbd)
I will be presenting some of my current work on emissions quantification as part of the NC State Marine, Earth and Atmospheric Sciences Seminar Series.
Additional events, future and past, are available on my events page.
Pendergrass, D.C. Jacob, D. J., Balasus, N., Estrada, L., Varon, D. J., East, J. D., He, M., Mooring, T. A., Penn, E., Nesser, H., & Worden, J. R. (2025). Trends and seasonality of 2019–2023 global methane emissions inferred from a localized ensemble transform Kalman filter (CHEEREIO v1.3.1) applied to TROPOMI satellite observations.

Figure: Annual posterior methane emission trends for 2019-2023 disaggregated by region and sector. Emissions are inferred using a localized ensemble transform Kalman filter applied to TROPOMI satellite observations. Panels (a) and (b) show posterior emission changes relative to 2019, disaggregated by region and sector respectively. Inset percentages show changes relative to 2019 values for selected regions/sectors. Error bars show range of the inversion ensemble for the global emission trend. Panel (c) shows 2019-2023 trends in posterior emissions by region obtained from linear regression.

Half-Earth Socialism is a book I co-authored with environmental historian Troy Vettese on how we can get out of our current ecological mess. Published in April 2022 by Verso Books, you can order it from the publisher here. The book has been translated into Italian, Thai, Korean, Spanish, and Swedish; all translations can be ordered from my books page.

My co-author Troy Vettese and I spoke with Emma Vigeland of the Majority Report about our book Half-Earth Socialism.

CHEEREIO is a tool that uses observations of pollutants in the atmosphere, measured from satellites or surface stations, to correct supercomputer models that simulate the Earth. Powerful use cases for CHEEREIO include tracking pollution back to its source, even if there are no local observations on the ground, and monitoring greenhouse gas emissions in near-real-time. Read more on my projects page or the offical CHEEREIO site.
