I am a professor of environmental history at Georgetown University. In my teaching and research, I bridge the humanities and the sciences to explore how societies have thrived - or suffered - in the face of dramatic changes in the natural world. I hope to glean lessons from the past that will help us confront our imminent future. I use public and digital histories to bring these lessons to journalists, policymakers, and the general public. 

In a forthcoming book, The Frigid Golden Age (Cambridge University Press), I explain how one society - the Dutch Republic - thrived as others faltered when volcanic eruptions and changes in solar radiation cooled Earth's climate between the sixteenth and eighteenth centuries. I am currently working on two new books: The Space Race, which traces how environmental changes in outer space helped shape the course of human history, and Coping with Climate Change, which unearths examples of societies that thrived amid natural and man-made climate changes over the past millennium.

I am the founder and director of HistoricalClimatology.com, a website that receives more than 300,000 hits annually. I am also the co-founder and co-director of the Climate History Network, an organization of nearly 200 academics in humanistic and scientific disciplines. I founded and now host the Climate History Podcast, and I founded Climate Tipping Points, a new project that aims to introduce a broad audience to the local consequences of climate change.
