As the [*New York Times* reports](), the City Council in Alameda, California has voted to end its pioneering marine geoengineering experiments, which involved spraying tiny particles of sea salt [off the deck of a decommissioned aircraft carrier]() in hopes of one day making clouds brighter and capable of reflecting sunlight away from our planet. Undertaken by climate researchers from the University of Washington, the beginning of the sun-dimming experiments — which, notably, had not yet begun seeding clouds with salt but were instead measuring the feasibility of the equipment being used — [made national news]() earlier this year, which per [*CBS News*]() took Alameda Mayor Marilyn Ezzy Ashcraft by surprise. Soon after that reporting, and after Tennessee banned similar experiments under the misguided notion that they constituted "[chemtrails]()," city officials [ordered the UW trial to a halt](), claiming that the researchers hadn't been transparent about what they'd be doing. The council commissioned an environmental assessment to determine whether or not spraying salt into the sky could be harmful to natural or human health. ## No Foul The ensuing environmental assessment found, as the [*NYT* noted in a previous report](), that the "chemical components of the saltwater solution (which is similar to seawater) being sprayed are naturally occurring in the environment." City staff recommended the experiment continue, citing the potential environmental benefits it could lead to. Nevertheless, after a lengthy meeting in which residents and council members voiced concerns about whether or not the geoengineering trial was truly harmless, the governing body voted unanimously to shut down the experiment. "I don’t think it’s appropriate for our community to be asked to bear that risk," councilor Trish Herrera Spencer said, per the *NYT*. "I don’t think this is the right place." Mayor Ashcraft echoed those concerns, saying she doesn't "have a huge desire to be on the cutting edge." "I just feel like this is not the right time," the mayor said. **More on climate change:** [*You Might Cry When You Read This Study About What's Happening to the Oceans*]() ## Author At Futurism, I've often been drawn to unpacking the narratives that underlie technological, scientific and medical progress, with a special interest in areas of conflict and ambiguity that end up setting agendas and steering the fates of both elites and the hoi polloi. I'm a committed generalist, but I often find myself returning to work involving NASA and the private space sector, the effects of AI on media and society, and the mechanics of the pharmaceutical industry, with a specific focus on the spread of GLP-1 drugs like Ozempic and Wegovy. Prior to Futurism, I worked for publications ranging from Media Matters and Truthdig to Raw Story and Bustle. I'm also the author of "Myspace Scene Queens," a 2024 title in Instar Books' acclaimed "Remember the Internet" series. My work at Futurism has been cited by outlets including the New Yorker, Slate, Nieman Lab, the Verge, the MIT Technology Review, the Sunday Times, and the Daily Beast. I grew up in North Carolina, attended the University of North Carolina at Asheville, and now live in Brooklyn, New York. In my free time, I'm an avid reader and music fan; you can probably find me at a local poetry reading, concert, underground rave, or DJ set. I'm the proud parent of an ineffable orange cat named Mee-Mow. ### Author social links [Bluesky]()
