Dakota Gruener and I have a new piece out in the new issue of @worksinprogress.bsky.social : worksinprogress.co/issue/sunscr...

Beautifully illustrated and clear write-up on SRM by @danvisioni.bsky.social and Dakota Gruener. worksinprogress.co/issue/sunscr...

Today we joined Natalie Mahowald, Lead Author of the IPCC 1.5SRE, to have a wide-ranging discussion on the topic of geoengineering, from the science to the governance challenges and ethical implications. Thanks to @cornelluniversity.bsky.social for organizing! www.youtube.com/watch?v=o15F...

Who would have guessed that putting together your own group of people to write an "assessment" with the specific goal from the beginning to come out with a specific set of conclusions, cherry-picking data, highlighting uncertainties to imply there is no understanding, ...

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.

Tomorrow is the start of my Climate Dynamics course. While I was incredibly excited to teach it before -I ❤️ this class- this year feels exciting in different ways: doesn’t matter who is in charge or what censorship they demand, physics’s physics. More motivated than ever to engage with my students!😎

Our paper exploring in depth the potential response of the Atlantic Meridional Circulation (AMOC) to Stratospheric Aerosol Injections led by Ewa Bednarz at NOAA CSL is now available online! Check out the paper here: agupubs.onlinelibrary.wiley.com/doi/10.1029/...

WG1, Chapter 9 reporting for duty 🫡 Very excited to participate in the next @ipcc.bsky.social Assessment Report, especially in a chapter with so many great colleagues and friends!

The @ipcc.bsky.social Seventh Assessment Report authors have been announced.

This thing we spread lies about is too controversial now and some people don’t like it, and it’s the scientists fault because of their lack of humility, so we’ll stop funding it completely. It’s just common sense!

The Data Foundation is fundraising for a new initiative that will coordinate efforts among nonprofits, experts & companies to modernize US greenhouse-gas measurements, striving to build on a Biden effort that Trump nullified on his first day in office.

The deadline for abstract submission is approaching!

Sorry but personally if a miniature horse woke me up from anesthesia by banging out nonsense on a miniature keyboard it would send me into a liminal space between life and death from which I would never return

🚨 Very, very big news. Today, a global coalition - including members of the IPCC, IPBES, and WHO expert advisors, as well as independent virologists, epidemiologists, and lawyers - started the process of creating an "IPCC for Pandemics." 🔓 www.thelancet.com/journals/lan... 🧵 Five things to know 👉

I don’t care if this was “the best” - it was incredibly entertaining and joyful, and a pleasure overall for sure - but it was definitely the Superman we needed, and also the one we collectively deserved after 7 months of putting up with cartoonishly evil shit.

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?

I’ve had senior colleagues in climate tell me doing SRM research was going to ruin my career since I started my PhD in 2016 (they’ve stopped now). I’ve persevered because, most of all, I felt it was the right thing to do. I’ll be damned if I let believers in “clean coal” scare me out of it now.

Seems good to repost this today!

Today, *every* living prior leader of NASA's science directorate have released a joint letter condemning the proposed cuts to NASA science. These individuals every administration from Reagan to Biden, and all believe these cuts are insanely destructive: www.planetary.org/press-releas...

I really try to swallow down snarky replies when I read these kind of things. Yes, I get the lure to say “time to give up” (especially at 89). But I don’t care. There’s just no “local solution” that protects vulnerable people and communities, sorry: I’m stubborn and annoying and just refuse to quit.

People who claim that we face a binary choice between “expanding access to air conditioning to save the lives of millions of largely poor people” and “mitigating climate change to save millions of lives” are, quite frankly, full of shit. We absolutely can do both, as the experts seem to agree.

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…

I am very diffident of accusations of “naïveté”. While they sound like a non-insult, they usually are nothing more than a charitable condescension that imply that the accuser is the navigated, smart one that can perceive complexity while everyone else is a simpleton with silly, monodimensional views

Wanted to make grim jokes about carbon budgets, decided not to. But, genuinely, what will the conversation be 3 years from now? Will scientists move on to discuss a carbon debt, or to a new 2C budget? What will headlines look like, and how will people react? Will they get tired of "dire warnings"?

Ultimately, climate models are worth defending for many reasons-they really are a surprising, communal achievement of so many different expertises working together (going to the CESM workshops is always so beautiful!). But the main reason might just be that they make everyone really big mad.

So the better question is: are the models adequate for purpose? They are adequate to understand physics, for scenarios exploration and broad associated risks; they might not be adequate for accurate prediction of tipping points & local risks. Unclear if both adequacies can be achieved at same time.

I didn't write the headline, but I do think some truly wild stuff is now on the table and we can't pretend otherwise www.wsj.com/science/envi...

Our Department (Earth and Atmospheric Sciences) at @cornelluniversity.bsky.social is hiring a Research Associate to work on ML/AI in weather and climate research - rather broad scope, and lots of freedom! Reach out if you want more info: academicjobsonline.org/ajo/jobs/29975

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?

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.

Happy Pride Month everyone 🩷❤️🧡💛💚🩵💙💜 This community’s here for you, whatever your career stage, however safe you feel coming out or not, know you are loved and you’ll always have a place. However dark these days might feel, know we will make it through together, in solidarity with one another 🏳️‍⚧️🏳️‍🌈

All due respect to the panelists, but hard disagree. EU policymakers know quite well how to wield the purse strings as a cudgel as well as, if not better than, the current US admin. Even now, most EU institutions pale in terms of research freedom compared to the US. This schadenfreude makes me sick.

Great, detailed paper finally out thanks to @wcrp-cmip.org reporting on the outcomes of ample consultations trying to assist the CMIP community in understanding what are the needs of different sets of users in terms of modeling output for CMIP7.

I've had to explain to *a lot* of Italians what Deep Dish Pizza is in the last 24h..
