A controversial experiment to artificially cool Earth was canceled — what we know about why

After years of legwork, Harvard researchers canceled plans to test a controversial theory for cooling the planet by sending sunlight-reflecting particles up into the atmosphere. Now, members of an independent advisory committee tasked with addressing ethics and safety concerns are sharing what they learned from the ill-fated project.

A policy analysis published in the journal Science on Friday highlights how important it is to talk to people on the ground before launching an experiment, especially one tied to potentially planet-altering consequences. The paper echoes recent calls to get policies in place to protect against any unintended side effects.

Until pretty recently, the thought of reflecting sunlight back into space to combat global warming — a process called solar geoengineering — seemed to be firmly rooted in science fiction. But with the climate crisis worsening, the idea has started to move from the fringes of academic research to garner more serious debate.

“Public engagement is necessary”

Some researchers and their Silicon Valley backers want to put the theory to the test. And time is running out to establish rules for how to craft those experiments responsibly, which could help determine whether solar geoengineering will do more harm than good.

“One of the core messages that comes out of this is that public engagement is necessary even when you don’t think that the impact of the experiment is going to be felt in a real way, in a concrete way, in real time. This issue has such a long tail, and it has such deeper meaning for so many people,” says Sikina Jinnah, lead author of the Science policy analysis and a professor of environmental studies at the University of California, Santa Cruz.

Harvard researchers launched the project called SCoPEx — short for Stratospheric Controlled Perturbation Experiment — back in 2017. To better understand any potential risks or benefits associated with solar geoengineering, it planned to conduct the first-ever outdoor experiment using reflective particles. It would have released some of those aerosols into the stratosphere via balloon and then piloted the balloon back through the plume to take measurements. The aim was to observe how the particles interact with each other and other elements of that environment — resulting in data that could be used to make more accurate computer models.

That never happened. There was supposed to be an engineering test flight without any particle release in Sweden in 2021, but it was scrapped after facing strong opposition from local Indigenous leaders. A big point of contention was that the researchers didn’t initially reach out to the Saami Council, which represents Saami Indigenous peoples’ organizations in the region. Members of SCoPEx’s advisory committee didn’t agree on whether to consult with the Saami since the test flight wasn’t going to release anything into the atmosphere, according to the policy analysis. The majority wound up deciding that the test flight could go ahead if there weren’t any significant environmental concerns to flag.

The Saami Council caught wind of the plans anyway and wrote a strongly worded letter to the advisory committee demanding the researchers cancel the flight. They said it was “remarkable” that the test flight would take place without consulting the Saami people or other local stakeholders, given the controversies swirling around solar geoengineering. Local environmental advocates, including Swedish chapters of Greenpeace and Friends of the Earth, also signed the letter.

Solar geoengineering is still considered a “false solution” to climate change by many activists. Injecting particles in the atmosphere attempts to recreate the way erupting volcanoes can temporarily cool the planet by releasing sulfur dioxide. But sulfur dioxide might also lead to acid rain, worsen the Antarctic ozone hole, or have other unforeseen consequences. There are also fears that solar geoengineering could detract from efforts to transition to clean energy, or lead to a dangerous swing in global temperatures if it’s ever implemented and then abruptly stopped.

“We note that [solar geoengineering using reflective particles] is a technology that entails risks of catastrophic consequences … There are therefore no acceptable reasons for allowing the SCoPEx project to be conducted either in Sweden or elsewhere,” the Saami Council letter says.

The advisory committee ultimately recommended canceling the test flight in Sweden after receiving that letter. By 2023, Harvard had told the advisory committee that it had “suspended” the project and then canceled it altogether in March of this year. The project “struggled both with intense media attention and with how to address calls from the scientific advisory committee to broadly and formally engage with the public,” Nature reported at the time, citing one of its project leaders.

“I’m grateful for the SCoPEx Advisory Committee’s insights. Their thoughtful analysis is valuable to the scientific community as it considers important questions of governance,” Frank Keutsch, who was the principal investigator for SCoPEx, tells The Verge in an email. He didn’t elaborate more on why the project ended.

It’ll take more than an ad hoc committee to effectively oversee geoengineering research moving forward, according to the newly published policy analysis. “The time is ripe for governments to begin discussing coordination of research governance,” it says.

Those talks have already started at the European Commission and the United Nations Environment Assembly, although they haven’t led to any concrete new policies yet. There has been a moratorium on large-scale geoengineering since a United Nations biodiversity conference in 2010, but it excludes small-scale scientific research.

And small fly-by-night initiatives have become a bigger concern lately. Last year, the founders of one geoengineering startup grilled fungicide in a California parking lot to produce sulfur dioxide gas that they then attempted to launch into the atmosphere via weather balloons. That followed a similar balloon launch in Mexico that prompted the government there to bar solar geoengineering experiments. The policy analysis calls the startup’s efforts “irresponsible” and “not tied to any legitimate scientific pursuit.”

Since then, there have been calls to either lay down rules for how to regulate future experiments or to stop solar geoengineering altogether. But without broader policies in place, keeping up with new geoengineering efforts gets to be a bit like playing whack-a-mole around the world.

Those policies could also ensure that nearby communities get to have a say in projects that might affect them. And as we’ve learned with SCoPEx, even more studious efforts can skip that step to their own detriment.

Defense secretary Pete Hegseth designates Anthropic a supply chain risk

This week, Anthropic delivered a master class in arrogance and betrayal as well as a textbook case of how not to do business with the United States Government or the Pentagon.

Our position has never wavered and will never waver: the Department of War must have full, unrestricted access to Anthropic’s models for every LAWFUL purpose in defense of the Republic.

Instead, @AnthropicAI and its CEO @DarioAmodei, have chosen duplicity. Cloaked in the sanctimonious rhetoric of “effective altruism,” they have attempted to strong-arm the United States military into submission – a cowardly act of corporate virtue-signaling that places Silicon Valley ideology above American lives.

The Terms of Service of Anthropic’s defective altruism will never outweigh the safety, the readiness, or the lives of American troops on the battlefield.

Their true objective is unmistakable: to seize veto power over the operational decisions of the United States military. That is unacceptable.

As President Trump stated on Truth Social, the Commander-in-Chief and the American people alone will determine the destiny of our armed forces, not unelected tech executives.

Anthropic’s stance is fundamentally incompatible with American principles. Their relationship with the United States Armed Forces and the Federal Government has therefore been permanently altered.

In conjunction with the President’s directive for the Federal Government to cease all use of Anthropic’s technology, I am directing the Department of War to designate Anthropic a Supply-Chain Risk to National Security. Effective immediately, no contractor, supplier, or partner that does business with the United States military may conduct any commercial activity with Anthropic. Anthropic will continue to provide the Department of War its services for a period of no more than six months to allow for a seamless transition to a better and more patriotic service.

America’s warfighters will never be held hostage by the ideological whims of Big Tech. This decision is final.

What Trump’s ‘ratepayer protection pledge’ means for you

NEWYou can now listen to Fox News articles!

When you open a chatbot, stream a show or back up photos to the cloud, you are tapping into a vast network of data centers. These facilities power artificial intelligence, search engines and online services we use every day. Now there is a growing debate over who should pay for the electricity those data centers consume.

During President Trump’s State of the Union address this week, he introduced a new initiative called the “ratepayer protection pledge” to shift AI-driven electricity costs away from consumers. The core idea is simple.

Tech companies that run energy-intensive AI data centers should cover the cost of the extra electricity they require rather than passing those costs on to everyday customers through higher utility rates.

It sounds simple. The hard part is what happens next.

Why AI is driving a surge in electricity demand

AI systems require enormous computing power. That computing power requires enormous electricity. Today’s data centers can consume as much power as a small city. As AI tools expand across business, healthcare, finance and consumer apps, energy demand has risen sharply in certain regions.

Utilities have warned that the current grid in many parts of the country was not built for this level of concentrated demand. Upgrading substations, transmission lines and generation capacity costs money. Traditionally, those costs can influence rates paid by homes and small businesses. That is where the pledge comes in.

What the ratepayer protection pledge is designed to do

Under the ratepayer protection pledge, large technology companies would:

Cover the full cost of additional electricity tied to their data centers
Build their own on-site power generation to reduce strain on the public grid

Supporters say this approach separates residential energy costs from large-scale AI expansion. In other words, your household bill should not rise simply because a new AI data center opens nearby. So far, Anthropic is the clearest public backer. CyberGuy reached out to Anthropic for a comment on its role in the pledge. A company spokesperson referred us to a tweet from Anthropic Head of External Affairs Sarah Heck.

“American families shouldn’t pick up the tab for AI,” Heck wrote in a post on X. “In support of the White House ratepayer protection pledge, Anthropic has committed to covering 100% of electricity price increases that consumers face from our data centers.”

That makes Anthropic one of the first major AI companies to publicly state it will absorb consumer electricity price increases tied to its data center operations. Other major firms may be close behind. The White House reportedly plans to host Microsoft, Meta and Anthropic in early March to discuss formalizing a broader deal, though attendance and final terms have not been confirmed publicly.

Microsoft also expressed support for the initiative.

“The ratepayer protection pledge is an important step,” Brad Smith, Microsoft vice chair and president, said in a statement to CyberGuy. “We appreciate the administration’s work to ensure that data centers don’t contribute to higher electricity prices for consumers.”

Industry groups also point to companies such as Google and utilities including Duke Energy and Georgia Power as making consumer-focused commitments tied to data center growth. However, enforcement mechanisms and long-term regulatory details remain unclear.

How this could change the economics of AI

AI infrastructure is already one of the most expensive technology buildouts in history. Companies are investing billions in chips, servers and real estate. If firms must also finance dedicated power plants or pay premium rates for grid upgrades, the cost of running AI systems increases further. That could lead to:

Slower expansion in some markets
Greater investment in renewable energy and storage
More partnerships between tech firms and utilities

Energy strategy may become just as important as computing strategy. For consumers, this shift signals that electricity is now a central part of the AI conversation. AI is no longer only about software. It is also about infrastructure.

The bigger consumer tech picture

AI is becoming embedded in smartphones, search engines, office software and home devices. As adoption grows, so does the hidden infrastructure supporting it. Energy is now part of the conversation around everyday technology. Every AI-generated image, voice command or cloud backup depends on a power-hungry network of servers.

By asking companies to account more directly for their electricity use, policymakers are acknowledging a new reality. The digital world runs on very physical resources. For you, that shift could mean more transparency. It also raises new questions about sustainability, local impact and long-term costs.

What this means for you

If you are a homeowner or renter, the practical question is simple. Will this protect my electric bill? In theory, separating data center energy costs from residential rates could reduce the risk of price spikes tied to AI growth. If companies fund their own generation or grid upgrades, utilities may have less reason to spread those costs among all customers.

That said, utility pricing is complex. It depends on state regulators, long-term planning and local energy markets.

Here is what you can watch for in your area:

New data center construction announcements
Utility filings that mention large commercial load growth
Public service commission decisions on rate adjustments

Even if you rarely use AI tools, your community could feel the effects of a nearby data center. The pledge is intended to keep those large-scale power demands from showing up in your monthly bill.

Kurt’s key takeaways

The ratepayer protection pledge highlights an important turning point. AI is no longer only about innovation and speed. It is also about energy and accountability. If tech companies truly absorb the cost of their expanding power needs, households may avoid some of the financial strain tied to rapid AI growth. If not, utility bills could become an unexpected front line in the AI era.

Here’s your first look at Kratos in Amazon’s God of War show

Amazon has slowly been teasing out casting details for its live-action adaptation of God of War, and now we have our first look at the show. It’s a single image but a notable one showing protagonist Kratos and his son Atreus. The characters are played by Ryan Hurst and Callum Vinson, respectively, and they look relatively close to their video game counterparts.

There aren’t a lot of other details about the show just yet, but this is Amazon’s official description:

The God of War series storyline follows father and son Kratos and Atreus as they embark on a journey to spread the ashes of their wife and mother, Faye. Through their adventures, Kratos tries to teach his son to be a better god, while Atreus tries to teach his father how to be a better human.

That sounds a lot like the recent soft reboot of the franchise, which started with 2018’s God of War and continued through Ragnarök in 2022. For the Amazon series, Ronald D. Moore, best-known for his work on For All Mankind and Battlestar Galactica, will serve as showrunner. The rest of the cast includes: Mandy Patinkin (Odin), Ed Skrein (Baldur), Max Parker (Heimdall), Ólafur Darri Ólafsson (Thor), Teresa Palmer (Sif), Alastair Duncan (Mimir), Jeff Gulka (Sindri), and Danny Woodburn (Brok).

While production is underway on the God of War series, there’s no word on when it might start streaming.
