Stardust recently released a set of preprints alongside a new website. We've been asked, more than once, what we make of it. The form matters as much as the content, and this reads as a product launch rather than a contribution offered up for scrutiny. Our longer answer below: bit.ly/4ugPe9L

Reading the Signals: Stardust and the Shape of an Emerging Field

A lot has already been said about Stardust, across media, within SRM research community, and among people thinking seriously about what the future of climate governance might look like. We wanted to t...

Grateful to have my perspectives included in this NYT piece on new announcements from Stardust. Companies cannot create their own rules and then applaud themselves for following them. That is not what legitimate or responsible research looks like. www.nytimes.com/2026/05/14/c...

DSG just returned from Cape Town, where we piloted a new approach to co-creating SRM research. The workshop gathered African civil society groups and researchers to develop research questions that reflect the needs of their communities and organizations.

Two new U.S. policy reports frame solar geoengineering as a national security battleground with China. An op-ed from @sktalati.bsky.social and @erinsikorsky.bsky.social argues that this narrative moves the conversation in the wrong direction.

@erinsikorsky.bsky.social and Shuchi Talati explains why viewing climate intervention technologies, like solar radiation modification, through the lens of security rhetoric alone is likely to poison the international environment that research and governance must take place.

Last week, Stardust Solutions publicly released a set of self-authored "Guiding Principles" and a proposed safety and controllability requirements framework. DSG has put out a statement on why, though these documents may look like governance, they are not. Read now: bit.ly/4vlccOQ

A Silicon Valley mindset doesn’t apply when you’re talking about intervening in the atmosphere, @sktalati.bsky.social and Janos Pasztor share in @lemonde.fr. As venture capital moves into SRM, the focus concerningly shifts “from inquiry to commercialization.” Read the piece: tinyurl.com/3w8jjx9t

Amid growing concern about climate impacts, governments are increasingly turning to the idea of solar geoengineering. As @sktalati.bsky.social writes, exploration of the controversial approach to climate mitigation will require clear governance to make ethical choices and maintain public trust.

The urgent need for research governance of solar geoengineering

Amid growing investment in planetary-scale climate intervention strategies that alter sunlight reflection, global communities deserve inclusive and accountable oversight of research.

The only path to legitimacy is to go slowly, as quickly as possible. @sehric.bsky.social‬ and @sktalati.bsky.social‬ reflect on this notion in DSG’s latest writing. Real-world examples show that rushed work on SRM doesn’t speed us up, it halts (and at times reverses) progress. Read: bit.ly/41af83p

I am grieving the barbarism that is going to unfurl from all this. People are going to die. Livelihoods gone. All to feed a corrupt kleptocracy. I see every day up close how different it is from the first time around. There are no guardrails. A disaster. I’m sorry we have to live through this.

Solar geoengineering conversation is picking up, and not necessarily in helpful ways. The only way to shift that is good information that is accessible to more people. Some thoughts from me in this piece 👇🏾

Science News@sciencenews.bsky.social · last yr.

Earth’s temperature keeps rising, and emissions aren’t dropping fast enough. So some scientists are considering solar geoengineering — reflecting sunlight to cool the planet.
