"Subduction" is a process that occurs when two tectonic plates collide with each other. As long as one of the plates is an "oceanic plate", then the denser of the two tectonic plates will be pushed under the less dense plate and subduction will occur. This phenomenon occurs all over the world, with the total length of subduction spanning more than 55,000 km. Apart from being a primary driver of plate tectonics, an important reason to study subduction zones is that they are the locus for some of the most devastating geologic hazards on Earth. Subduction zones produce the largest magnitude earthquakes on the planet and they lead to consistent volcanic activity on the plate that lies above the sinking plate. One important consideration for understanding these geologic hazards is how water influences their evolution.

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.

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.)
