Experiments to dim the Sun get green light

Tue, April 22, 2025 at 8:17 PM GMT+1

Experiments to dim sunlight to fight global warming will be given the green light by the Government within weeks.

Outdoor field trials which could include injecting aerosols into the atmosphere, or brightening clouds to reflect sunshine, are being considered by scientists as a way to prevent runaway climate change.

Aria, the Government’s advanced research and invention funding agency, has set aside £50 million for projects, which will be announced in the coming weeks.

Prof Mark Symes, the programme director for Aria (Advanced Research and Invention Agency), said there would be “small controlled outdoor experiments on particular approaches”.

“We will be announcing who we have given funding to in a few weeks and when we do so we will be making clear when any outdoor experiments might be taking place,” he said.

Re-freezing the Arctic? A giant sea curtain? High-tech efforts to save the ice sheets are doomed, report finds


Sep 9, 2025

Moonshot proposals to save the planet’s ice sheets, including giant underwater sea curtains and refreezing Arctic ice, are gaining popularity as the planet heats up. But none of the most high-profile ideas are viable — worse, they may cause irreparable harm, according to a new study published Tuesday.

The melting of the vast polar ice sheets has become a byword for climate change; these giant frozen landscapes hold enough water to cause catastrophic sea level rise and are experiencing alarming changes as temperatures increase.

Ideas to artificially cool the Arctic and Antarctic, known as “polar geoengineering,” are gaining profile as a result. Academics have launched research projects, start-ups are proliferating and investors are piling in.

Geoengineering advocates say the urgency of the climate crisis makes it vital to research these potential fixes. The authors of the report, published in the journal Frontiers in Science, say they are a dangerous distraction.

“These ideas are often well-intentioned, but they’re flawed,” said Martin Siegert, a glaciologist at the University of Exeter and a study author. He and a team of international scientists analyzed five of the most well-publicized ideas:

What Are the Risks of Geoengineering to Fight Climate Change?
By Harrison Tasoff
September 17, 2025

Introduction:

(Futurity) With CO2 emissions continuing unabated, an increasing number of policymakers, scientists, and environmentalists are considering geoengineering to avert a climate catastrophe. Such interventions could influence everything from rainfall to global food supplies, making the stakes enormous.

In brief, manipulating other aspects of Earth’s climate system might reduce some effects of climate change. But the wondrous complexity of our planet complicates every one of these proposals.

Climate scientists at the University of California, Santa Barbara analyzed two approaches that involve reducing the amount of sunlight warming Earth’s surface: cloud seeding over the eastern Pacific and introducing aerosols into the stratosphere.

By modeling local effects on the Pacific Ocean, they found that the first strategy would completely disrupt one of the planet’s major climate cycles, the El Niño Southern Oscillation. At the same time, the second would scarcely affect the system at all. The results in the journal Earth’s Future underscore the importance of considering the broad range of consequences that any geoengineering solution may have.

The Strange and Totally Real Plan to Blot Out the Sun and Reverse Global Warming
By Karl Mathiesen and Corbin Hiar
November 21, 2025

Introduction:

(Politico) Janos Pasztor was conflicted. Sitting in his home office in a village just outside Geneva, he stared into the screen of his computer, where a bizarre Zoom call was taking place. It was Jan. 31, 2024. The chief executive of an Israeli-U.S. startup, to whom Pasztor had only just been introduced, was telling him the company had developed a special reflective particle and the technology to release millions of tons of it high into the atmosphere. The intended effect: to dim the light of the sun across the world and throw global warming into reverse. The CEO wanted Pasztor, a former senior United Nations climate official, to help. The company called itself Stardust Solutions.

Pasztor, a deliberate and self-assured Hungarian with thick, arched eyebrows that give him the appearance of a mildly perturbed owl, was stunned by the seriousness of Stardust’s operation. He had long been expecting that some company would try this. But the emergence of a well-financed, highly credentialed group represented a shocking acceleration for a technology still largely confined to research papers, backyard debates and science fiction novels.

The Stardust CEO, Yanai Yedvab, was a nuclear physicist who was once deputy chief scientist at the Israeli Atomic Energy Commission, and he jumped straight to the point. He wanted Pasztor to advise him on how to build public credibility, which would be necessary to land the government contracts for sunlight reflection that the company and its investors were banking on. The CEO appeared keenly aware that Stardust had the potential for the kind of public image problems normally reserved for James Bond villains. Those challenges were likely not made easier by picking a company name that echoed Star Wars’ “Project Stardust” — the codename the bad guys in the Galactic Empire used for the Death Star, a weapon designed to destroy entire worlds.

Can Fungi Control the Weather? Scientists Say It’s Possible

A vast dam across the Bering Strait could stop the AMOC collapsing

If a key ocean current collapses it could plunge northern Europe into a big freeze. Now researchers are weighing up a drastic intervention – building a 130-kilometre-wide dam between the US and Russia

9 May 2026

It would be an engineering project on a truly epic scale, but we may one day need to consider building a dam between Alaska and eastern Russia. The audacious proposal would be designed to stave off the worst consequences of the collapse of a vital ocean current, and researchers have been mulling it over this week at a major conference.

The idea comes from Jelle Soons and his colleague Henk Dijkstra at the University of Utrecht in the Netherlands, who study the Atlantic Meridional Overturning Circulation or AMOC. This current system, which includes the Gulf Stream, is a major reason why northern Europe has a relatively mild climate for its latitude.

However, we know the current is weakening. There is huge uncertainty about what would happen if it collapses, but some models suggest it could see temperatures in northern Europe drastically plunge.

[...]

In work published a few weeks ago, Soons and Dijkstra obtained mixed results: in some scenarios the dam appeared to strengthen the AMOC, but in others it had the opposite effect. However, those results came from a relatively simple and low-resolution model.

On 5 May at the European Geosciences Union general assembly in Vienna, Austria, Soons presented work that repeated the simulations on a supercomputer using a much more advanced climate model. This indicated that closing the Strait would strengthen AMOC, especially if the dam were built early – by at least 2050. “I was surprised at how strong the recovery was,” says Soons.
