Great to join @miquai.bsky.social and the folks at @carnegiescience.bsky.social this morning to talk about Ripples on the Cosmic Ocean and, among other things, the existential risk of #SolarStorms. Check out Mike’s forthcoming book - an argument for a new force of nature! #Space

I really enjoyed doing this interview with Isaac Randel of Foreword Reviews. The questions were incredibly thought-provoking, exploring everything from today's existential risks to the history of the search for alien life. #EnvHist #Space www.forewordreviews.com/articles/art...

A book I love assigning to my grad students: Katrin Kleemann's "Mist Connection." Katrin provides a truly multidimensional account of the short- and long-term impacts of 1783 Laki fissure eruption, one of the most interesting volcanic events in #EnvHist. library.oapen.org/handle/20.50...

A special honor to be back at #NASA HQ last week. Drawing on the research in my new book, Ripples on the Cosmic Ocean (out on October 28!), I traced some ways in which the search for life on other worlds is helping us understand - and, hopefully, preserve - the future of life on Earth. #Astrobiology

Delighted to see this new review of "Ripples on the Cosmic Ocean," a book that pulls "earthlings out of their complacency to recognize the precarity of their position amid ongoing cosmic dramas." Now available for pre-order! #Space #EnvHist www.forewordreviews.com/reviews/ripp...

New #EnvHist article!
In this collaboration with art historian Rachel Kase, I explore what the visual legacy of #Arctic whaling can tell us about the possibilities - and perils - of #ClimateChange adaptation.

In "Ripples on the Cosmic Ocean," my forthcoming book, I explain how scientists and engineers grappled with the threat seemingly posed by small asteroids. The asteroid detection programs they created represent one of modern society's most successful responses to existential risk. #EnvHist

I also break down some of the creative detective work that archaeologists use to uncover the deep past, and I explain what it can - and can't - tell us about our distant ancestors. You can find the episode wherever you download your podcasts, or at theclimatechronicles.com. #EnvHist
