I just finished this fantastic trilogy of 80s feminist sci-fi (I’d never heard about before going to my local bookstore!) that explores a future world where the 19th amendment has been repelled [then many wacky things happen in pure 80s sci-fi style]. A good reminder of how flimsy progress is..

I’m sure is just a coincidence, but the Syracuse Orchestra today is playing Beethoven’s Seventh, which premiered at a concert celebrating Napoleon’s defeat. He dedicated the Third to Napoleon as a champion of liberty, but ripped the dedication from the manuscript when he declared himself Emperor.

I just finished reading “The Terraformers” by @annaleen.bsky.social and it made me so happy I need to share it here. It is rare to find such forward-looking, powerful sci-fi that manages to be hopeful about humanity while not shying away from its problems.

Out as preprint, we have some very interesting results looking at the radiative forcing impacts of the 2022 Hunga eruption. Based on the outcomes of the related OMIP, with many models from all over the world participating in this effort, we find a robust cooling signal from the Hunga volcanic plume.

Nothing. You can spend the whole day clicking every link in the CGD website and you won’t find the acronym spelled out anywhere… www.cgd.ucar.edu/about/missio...

Been thinking a bit about this long exchange I read here yesterday about AC being a luxury or not. I think this is the largest obstacle to framing degrowth around “sufficiency” for me: you’ll always find someone that finds your necessity as a luxury. What if they’re in charge of what you can have?

Ryan O’Loughlin and I have a new preprint where we ask: When are small-scale field experiments in solar geoengineering worth pursuing? philsci-archive.pitt.edu/25840/
We contrast concepts of “luxury” and “moonshot” research as a starting point to discuss criteria that could guide the community…

This started from an observation: if SRM is “cheap and easy”, and including it in an Integrated Assessment Model makes it always happen… why isn’t the world doing SRM? We explain this by discussing different phases in which risks perception play different roles in shaping how SRM is conceived.

Can we make testable hypothesis about how the perception itself of SRM -from publics, countries, decision makers- would affect different futures? And if yes, how do we go about building 1? What can outlining & modeling assumptions about how risks of climate change and of SRM tell us about our world?

@hollyjeanbuck.bsky.social called this one first (and was attacked for it) www.compactmag.com/article/the-.... What is the point of lying so stupidly about things as different as fluoride, EM radiation, vaccines and geoengineering (even if the latter currently doesn't exist)? I have some ideas.

As you can see, you have it reversed. Now, I don’t think that crazy wackos being against something is necessarily a good reason why one should be pro something, nevertheless, these are the facts.

I’ve told MS, publicly, that their stunt was silly and it was going to make serious discussions about SRM harder. But I won’t enjoy seeing them attacked by a government that, at the same time, pretends “clean coal” is a thing while pearl-clutching about “polluting our air” with 10 grams of sulfate.

Ok, fine, they change this f*ing website once every two months... you COULD edit your searches before, I'm sure. Anyway, I tested and using the search bar and typing the variables works for me...!

One of these things is unpleasant, perhaps unavoidable, some would say natural, some not, but definitely needs to be talked about. The other is, uhm, pregnancy.

The same government wants to make you believe they’ll ban something that doesn’t exist -something that it’s being discussed, scientifically, mainly *because* climate science has provided such robust and dire warnings about the consequences of climate change- while actually dousing you in toxins.

Here a photo of our Slope, with the lake visible in the distance, and the students soaking up the sun under a blue blue sky. I promise there’s also some green, just outside of the picture. But it’s there.
