At least for CO2 itself (not all the GHGs), we can very nearly close the global budget. So, the reporting may be imperfect, but plateauing of fossil CO2 emissions is not a reporting error. Let's not ignore that improvement really is happening.

20 years ago, global greenhouse gas emissions were rising at ~half a billion tons of CO2e per year. Today, they're almost steady.
A lot work to do to drive the emissions (and not just its rate of change) to zero. Celebrate progress and keep shoulder to the wheel.

Right on, Jess! So many reasons to get started doing oceanography ... but one of the main things that keeps me going is the community and people (like you). Yes, let's keep at it and help each other weather the headwinds and tailwinds along the way.

Something that made me feel good this week: After listening to @volts.wtf podcast with www.undauntedk12.org, I wrote the members of my town's school committee. Two members already got back to me to say thanks, and one said they are already evaluating geothermal heating for the new school building.

That's a nice graphic. I know there must be stuff out there -- just want it packaged up nicely. Gardiner and Nichols (2012) have a book, reviewed here: www.nature.com/scitable/kno...
A bit dry, but a nice overview

Undergraduates would likely find it accessible -- great recommendation. I'm also wondering about ethical obligations to non-human components of the world. I'll see if there's a chapter of Braiding Sweetgrass that would capture it...But would also take other tips :)

Does anyone have a favorite advanced undergraduate-appropriate reading related to the ethics of climate change and its mitigation (or adaptation)? This would be background for 1-week of the class, so article length (or single book chapter) would work best.

Yes, and we'll never undo mCDR as a concept entirely. But I think we may be at a precarious moment when differentiation/discernment is especially valuable. Fears disproportionate to true risk could halt research-scale deployments that pass the strictest standards of safety.

If there are methods that are going by the same umbrella term of mCDR but are too risky or obvious dead-ends, what is gained by sharing a moniker with them?

Totally agree! We walk a razor's edge. On one side: people hear "chemical mCDR" and are terrified, thereby arresting research. A potential solution withers on the vine. On the other side: finding reassuring words to help the public understand/embrace responsible research could lead to PR hogwash.

I especially like this idea. From an oceanographic, biogeochemical, and fisheries perspective, the ocean science community could test the hypothesis that some of these methods are restorative. I suspect the same could happen on the social side.

DOR would return seawater to a chemical state closer to pre-anthro perturbation (but filters water). OAE shifts the partitioning of DIC closer to preindustrial, but with the goal of having more total DIC in the end.

I think "ecological manipulation" is an honest description of the biological methods. "Seawater restoration" is okay but uncomfortable:

Thank you for these thoughtful responses! We currently use value-neutral terminology (Ocean Alkalinity Enhancement, Direct Ocean CO2 Removal, Iron Fertilization). The terms are not legible to folks outside of ocean sciences. My proposed terms are certainly value-laden, but that's with intention...

Proposal: Unbundle the methods, stop calling it mCDR, and talk about “Restoring Seawater” to realize its CO2 uptake potential. It could help the public understand what Direct Ocean Removal and Ocean Alkalinity Enhancement have in common and avoid conflation with ecosystem manipulation.

The more I think about it, the more the term "mCDR" seems problematic. It lumps methods that would manipulate ecosystems (e.g. iron fertilization, macroalgae cultivation) with totally unrelated approaches that use the natural properties of seawater to accomplish CO2 drawdown from the atmosphere🧵 1/2

Cars also ruin desserts. My only crash happened directly after visiting a German bakery. Jelly-filled pastries flew everywhere and it took me several minutes to realize my passenger and I weren't bleeding.

Wow - I was not aware of this publication. Such an ingenious series of calculations that now form the first weeks of many classes on climate. Interesting that he did not consider the effect of the terrestrial biosphere.
