A Remote Sensing Solution for Nitrous Oxide: The Greenhouse Gas We Need to See Better

When we talk about greenhouse gases and climate change, carbon dioxide (CO2) and methane (CH4) usually receive most of the attention. Yet another gas, nitrous oxide (N2O), quietly plays an important role in our changing climate. Commonly known as "laughing gas", N2O is a powerful greenhouse gas with nearly 273 times the warming potential of CO2 over a 100-year period. Once released, it can remain in the atmosphere for more than a century. During this time, it contributes not only to global warming but also to the depletion of stratospheric Ozone. Its atmospheric concentration has been increasing, largely due to human activities, with nitrogen-based fertilizers used in agriculture being an important contributor.

Speculative sauropods

If you travel in the same circles I do, you probably know that my friend and colleague Mark Witton is working on a speculative biology book, Dinosaurs Evolved, that takes a fresh look at what life on Earth might be like now had the asteroid missed and the K-Pg extinction never happened. As a lifelong spec-bio fan, I'm stoked for that project. Speculative sauropods have given me a lot to think about, especially in the past few years, so I thought it would be fun to revisit some in this post. Maybe all? There aren't a ton of examples. If you know of any I missed here, sing out in the comments. (I'm not including any from the Speculative Dinosaur Project out of lack of familiarity -- the project was basically dead by the time I would have started following it -- and I'm not sure any are currently accessible anyway.)

New papers on paleoseismology, active tectonics, and archaeoseismology (Oct 2026)

Paleoseismicity | 1 October, 2026
This time we have two whole books in our list that will be surely of interest. One is about Himalayan Hazards, the other one is about the geomorphological impact of earthquakes. A rather large number of studies deals with faults, tsunamis, and earthquakes in Europe. Of course we also have plenty of papers covering other regions and methodological studies.Enjoy reading!

SV-POW! at 19, and trying to see what’s not there

Today is SV-POW!'s birthday. Not a nasty, dirty, wet birthday, like a 2nd or a 13th, nor yet a grand, nice-round-number birthday like a 10th or a 20th: it is our 19th birthday, and that means we've been around a while. I decided to celebrate by posting surprising facts about RNA.
