War Game Exposes Geopolitical Risks of Solar Geoengineering

How the simulation unfolded

In October 2026, researchers and policymakers gathered at Queen Mary University of London for a simulation titled Exploring Geopolitical Tipping Points and Climate Cooling Strategies. The goal was to test how global powers would respond to solar radiation modification (SRM) technologies, which aim to reflect sunlight to cool the planet.

Participants role-played as governments, climate NGOs, indigenous groups, and tech companies. According to WIRED, the exercise quickly devolved into distrust, with the US, China, and Russia prioritizing national interests over cooperation. No agreements were reached despite multiple proposals.

Russia accused the US of conducting geoengineering research near the Bering Strait, while the US suspected China of covert experiments. Neither claim was verified during the simulation. The US and China refused to sign any deal that constrained their "national interest" or allowed their rival to lead technologically.

Private sector and fossil fuel influence

Private firms and industry-backed groups played a disruptive role in the simulation. Stardust Solutions, a US-based startup, raised $60 million and announced a suite of inventions claiming to enable precise control over global temperatures. According to WIRED, the company pledged not to deploy its technology without global governance but did not rule out large-scale experiments.

The Climate Futures Cooperative, later revealed to be backed by the fossil fuel industry, offered funding to participants to discredit scientific advice. WIRED reported that this was part of a broader strategy to remove barriers to geoengineering development, aligning with the interests of fossil fuel companies and major producing nations like the US and Saudi Arabia.

Real-world parallels

The simulation’s outcomes mirror real-world geopolitical tensions. In the US, conservative think tanks have urged the government to lead in SRM technology to counter China’s influence. A UK Ministry of Defense-backed report explored sunlight reflection, while the British government released its first policy paper on SRM, supporting research but rejecting deployment.

According to WIRED, these developments suggest that global governance frameworks for SRM are urgently needed to prevent a competitive arms race. The simulation’s organizer, Danielle Young of Leeds University, warned that decisions about SRM governance may be necessary far sooner than policymakers anticipate.

The risks of solar geoengineering

Solar radiation modification aims to mimic the cooling effect of large volcanic eruptions by reflecting sunlight away from Earth. However, its potential consequences are poorly understood. Some regions could face severe side effects, such as droughts in sub-Saharan Africa or intensified tropical storms in the Atlantic, according to WIRED.

The cooling effect would only last as long as geoengineering efforts continued. If halted abruptly, global temperatures could rebound rapidly, leading to unpredictable and potentially catastrophic outcomes. Critics argue that SRM distracts from emissions reductions and could be weaponized or exploited for geopolitical advantage.

What this means

Lazyfounder analysis — our interpretation, not reported fact.

This simulation serves as a warning for founders and policymakers alike. Climate technologies with global implications cannot be developed in a vacuum—they require robust governance frameworks to prevent geopolitical conflicts from derailing progress. The exercise demonstrated how easily misinformation, strategic rivalry, and corporate interests can undermine collaboration, even when the stakes are existential.

For startups in the climate tech space, the lessons are clear: transparency, international alignment, and proactive engagement with regulators are not optional. The risk of a fragmented or competitive approach to SRM could lead to fragmented markets, regulatory backlash, or even a moratorium on deployment. Founders must also be wary of becoming pawns in larger geopolitical games, particularly if their technologies are seen as instruments of national power rather than global solutions.

Key takeaways

• Founders in climate tech must anticipate geopolitical fragmentation when scaling technologies with global implications.
• Distrust and misinformation can derail even well-intentioned scientific collaborations, requiring proactive governance strategies.
• Private sector involvement in emerging climate technologies may face resistance unless transparency and alignment with global interests are prioritized.
• Regulatory and governance frameworks for SRM and similar technologies are urgently needed to prevent a competitive arms race.
• Simulations like this highlight the risks of allowing nationalistic or corporate agendas to dominate climate solutions.

FAQ

What is solar radiation modification (SRM)?

SRM refers to technologies designed to reflect sunlight away from Earth to cool the planet. This can mimic the effect of large volcanic eruptions, but its long-term consequences are not fully understood.

Why did the simulation fail to produce an agreement?

The simulation collapsed due to distrust, misinformation, and strategic rivalry among participants. The US and China refused to agree to any deal that constrained their "national interest" or allowed their rival to lead in SRM technology.

How are fossil fuel companies involved in SRM?

The simulation revealed that groups backed by the fossil fuel industry, such as the Climate Futures Cooperative, sought to undermine scientific advice and remove barriers to SRM development, aligning with their interests in delaying emissions reductions.

Are governments already taking steps toward SRM?

Yes. The UK has released policy papers supporting SRM research, while US think tanks have urged the government to lead in the technology to counter China’s influence. The UK Ministry of Defense has also funded research into sunlight reflection.
