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

In the late 1800s alien ‘engineers’ altered our world forever | Aeon Essays Images of vast ‘canals’ rippling across the red planet inspired fears of alien ‘engineers’ and changed science forever

I love publishing with @aeon.co. In this article, come for the UAPs (!), stay for the Martian canal-builders - and the history of how they changed our ideas about the environment, our future, and our place in the universe. #EnvHist #Aliens #Mars #History aeon.co/essays/in-th...

Three new interviews about the #EnvHist of outer space and climate change!

It was an absolute delight to chat about "Ripples on the Cosmic Ocean" with Sarah Al-Ahmed at Planetary Radio, one of my favorite podcasts. Check it out here: www.planetary.org/planetary-ra... (1/3)

On the 19th-Century Scientist Who Realized Solar Storms Influence Life on Earth When thirty-three-year-old Richard Carrington settled down to sketch sunspots on the morning of September 1, 1859, he could not have known that he was about to witness the most important change eve…

In 1859, a solar storm of staggering power revealed that while technological progress had provided new powers over environments on Earth, it had also created vulnerabilities to environments in space. Read more in this excerpt from Ripples on the Cosmic Ocean! #EnvHist lithub.com/on-the-19th-...

Solar storms have influenced our history – an environmental historian explains how they could also threaten our future From communications outages to a brush with nuclear war, solar events like flares and coronal mass ejections have shaped human history.

My new book, "Ripples on the Cosmic Ocean," was published today! And here's a new article in @theconversation.com that explains how #solarstorms have influenced #history, and may threaten our future. Spoiler: it's really not a good idea to cut science at NASA. theconversation.com/solar-storms...

Tomorrow morning EST: I'm doing a Reddit AMA with r/AskHistorians and r/AskScience. I'll answer any and all questions about #ClimateChange, space history, environmental history, and anything else people want to talk about - including "Ripples on the Cosmic Ocean," my next book. #EnvHist

How Math Helps Us Map The World In "Mapmatics," a mathematician tells the stories of how math helps us track epidemics, map the seafloor, and plot a complex delivery route.

What can be used to track epidemics, catch criminals, and calculate the deepest depths of the ocean floor? A map, of course! Journey with us through the mathematics at the heart of all sorts of maps. 🗺️

Something New Around the Sun: The Case for an Environmental History that Spans the Cosmos Environmental history studies past interactions between humans and nature—expanding from Earth’s ecosystems to the dynamic, interconnected environments of the entire universe.
