Why the for-profit race into solar geoengineering is bad for science and public trust
—David Keith is the professor of geophysical sciences at the University of Chicago and Daniele Visioni is an assistant professor of earth and atmospheric sciences at Cornell University
Last week, an American-Israeli company that claims it’s developed proprietary technology to cool the planet announced it had raised $60 million, by far the largest known venture capital round to date for a solar geoengineering startup.
The company, Stardust, says the funding will enable it to develop a system that could be deployed by the start of the next decade, according to Heatmap, which broke the story.
As scientists who have worked on the science of solar geoengineering for decades, we have grown increasingly concerned about emerging efforts to start and fund private companies to deploy technologies that could alter the climate of the planet. We also strongly dispute some of the technical claims that certain companies have made about their offerings. Read the full story.

Can “The Simpsons” really predict the future?
According to internet listicles, the animated sitcom The Simpsons has predicted the future anywhere from 17 to 55 times.
The show foresaw Donald Trump becoming US President a full 17 years before the real estate mogul was inaugurated as the 45th leader of the United States. Earlier, in 1993, an episode of the show featured the “Osaka flu,” which some felt was eerily prescient of the coronavirus pandemic. And—somehow!—Simpsons writers just knew that the US Olympic curling team would beat Sweden eight whole years before they did it.
Al Jean has worked on The Simpsons on and off since 1989; he is the cartoon’s longest-serving showrunner. Here, he reflects on the conspiracy theories that have sprung from these apparent prophecies. Read the full story.

MIT Technology Review Narrated: Therapists are secretly using ChatGPT. Clients are triggered.
Declan would never have found out his therapist was using ChatGPT had it not been for a technical mishap where his therapist began inadvertently sharing his screen.
For the rest of the session, Declan was privy to a real-time stream of ChatGPT analysis rippling across his therapist’s screen, who was taking what Declan was saying, putting it into ChatGPT, and then parroting its answers.
But Declan is not alone. In fact, a growing number of people are reporting receiving AI-generated communiqués from their therapists. Clients’ trust and privacy are being abandoned in the process.

One more thing
Is the digital dollar dead?
In 2020, digital currencies were one of the hottest topics in town. China was well on its way to launching its own central bank digital currency, or CBDC, and many other countries launched CBDC research projects, including the US.
How things change. Years later, the digital dollar—even though it doesn’t exist—has become political red meat, as some politicians label it a dystopian tool for surveillance. And late last year, the Boston Fed quietly stopped working on its CBDC project. So is the dream of the digital dollar dead? Read the full story.
