When climate researcher Colleen Golja accepted an invitation to participate in a high-level geopolitical simulation in London, she operated under a comforting, foundational assumption: that empirical science, rational discourse, and objective reason would retain a guiding voice in shaping humanity’s response to planetary crises. By the conclusion of the multi-day exercise, however, that bedrock certainty had entirely shattered.
Entitled Exploring Geopolitical Tipping Points and Climate Cooling Strategies, the war game was designed to stress-test international governance against the emergence of solar radiation modification (SRM)—a suite of controversial geoengineering technologies aimed at cooling the Earth by reflecting sunlight back into space. Conceived by Leeds University international relations assistant professor Danielle Young and funded by the UK government’s Advanced Research and Invention Agency (ARIA), the simulation brought together diplomats, military attachés, national security experts, and scientific advisors to navigate a simulated future of escalating climate chaos and technological breakthroughs.
Instead of yielding collaborative agreements or science-backed stewardship, the room devolved into a theater of acute paranoia, national sovereignty posturing, and covert sabotage. Rather than acting as a neutral arbiter, science was sidelined, ignored, or weaponized.
The simulation’s grim trajectory offers an alarming preview of our near future. As global temperatures surge past historical thresholds and private sector startups aggressively commercialize climate-altering technologies, humanity is hurtling toward a high-stakes geopolitical arms race over the global thermostat. Decisions regarding the manipulation of Earth’s atmosphere are no longer a matter of distant science fiction; they are on the immediate horizon, threatening to upend international stability within the decade.
Detailed Chronology: Anatomy of a Simulation Breakdown
The war game unfolded over a series of simulated meetings staged across three distinct chronological markers: the present day, September 2027, and September 2028. Hosted in a meeting room at Queen Mary University of London, the simulation placed participants behind tables marked with the designations of national governments, indigenous coalitions, non-governmental organizations, and emerging tech companies.
Phase 1: The Present Day and the Erosion of Trust
The opening session immediately established a toxic climate of deep distrust and strategic posturing. As delegates attempted to draft an international framework regulating outdoor geoengineering experiments, representatives for both the United States and China drew hard red lines. Both superpowers declared they would refuse any agreement that constrained research deemed vital to their "national interest," or any deal that granted their geopolitical rival a technological edge.
"Worse than no deal at all is any deal that favors China," summarized US Army Major Jeffrey Nielsen, who participated in the simulation as a US national security attaché.
The tension sharply intensified when organizers injected a simulated intelligence report into the room, informing Russian delegates of an unidentified aircraft near the Bering Strait suspected of conducting clandestine US geoengineering research. While US research flights were indeed occurring, American delegates vehemently accused Moscow of disinformation.
Concurrently, US intelligence grew convinced that Beijing was covertly developing its own independent solar geoengineering program. When Chinese delegates attempted to negotiate language shielding past experiments from retroactive penalties, they simultaneously approached a participant role-playing a SpaceX representative to float a bilateral technology-sharing initiative. The SpaceX delegate immediately leaked the overture to the US team, prompting fierce American demands for international investigations. The talks collapsed entirely, culminating in a poignant assessment by the Canadian representative: a "humiliating defeat."
Phase 2: Escalation and the Fossil Fuel Interloper
As the simulation advanced into its 2027 and 2028 timelines, organizers sought to refocus delegates on intensifying real-world climate emergencies, feeding regular updates into the room detailing historic droughts, extreme heatwaves, and localized environmental collapses. Yet, these warnings barely registered amid the relentless maneuvering for strategic advantage.
Scientific advice, embodied largely by Golja’s technical briefings and her custom-built climate emulator, was routinely bypassed. When delegates did consult her, it was rarely to understand physical atmospheric dynamics; rather, they weaponized leading questions to extract data that could justify their own political agendas or frame rival proposals as reckless.
The breaking point arrived during the final day’s session, centered on an international crisis triggered by the detection of a massive aerosol plume. The anomaly was the result of a joint US-Saudi test utilizing the technology of Stardust Solutions, a real-world private startup.
At this critical juncture, an NGO calling itself the Climate Futures Cooperative (CFC) approached Golja, offering substantial financial backing to establish an independent satellite-monitoring network that could prevent secret geoengineering deployments. For Golja, the offer felt like a lifeline.
The relief was short-lived. It soon emerged that the CFC was a front organization quietly bankrolled by the fossil fuel industry. Major carbon-producing states and fossil fuel conglomerates shared a clear, unstated incentive: to remove regulatory hurdles from geoengineering technologies that could temporarily mask global warming, thereby relieving political pressure to immediately phase out coal, oil, and gas.
While savvy players—including Russia, the US, and representatives from SpaceX and Stardust—quickly recognized the CFC’s true backing, they calculated that the NGO’s disruptive presence served their strategic interests and elected to say nothing. When the CFC ultimately moved to offer funding to Golja, its true objective was realized: cratering scientific credibility, isolating empirical expertise, and completely fracturing the collective voice of reason in the room.
By the final gavel, no international accord had been reached. The simulation’s final report concluded bluntly: "Strategic competition and state sovereignty drove the simulations, not climate concerns."
Supporting Context & Metrics: The Science and Stakes of SRM
To understand the ferocious geopolitics animating the London war game, one must examine the underlying mechanics, staggering implications, and rapid commercialization of solar radiation modification.
The Mechanics of Cooling the Planet
Solar radiation modification mimics the cooling aftermath of massive volcanic eruptions, such as the 1991 Mount Pinatubo explosion in the Philippines, which temporarily lowered global average temperatures by roughly 0.5 degrees Celsius by injecting millions of tons of sulfur dioxide into the stratosphere. Proposed SRM interventions typically involve deploying aircraft, high-altitude balloons, or specialized maritime systems to disperse reflective aerosols—such as sulfur dioxide, diamond dust, or manufactured engineered particles—into the upper atmosphere.
The Unequal Fallout and Regional Risks
While the cooling efficacy of solar geoengineering is widely accepted by atmospheric modelers, its secondary fallout is profoundly uncertain and highly inequitable. Climate models project that artificial cooling could trigger severe regional anomalies, including catastrophic drying across sub-Saharan Africa and intensified tropical cyclone activity in the Atlantic basin. Furthermore, SRM introduces the "termination shock" hazard: because engineered aerosols settle out of the atmosphere within one to two years, ongoing injections must be maintained indefinitely. If a geopolitical conflict, economic collapse, or technical failure interrupts the program, global temperatures would violently rebound at unprecedented speeds, unleashing ecological catastrophes far more severe than gradual warming.
The Commercial Gold Rush
Until recently, geoengineering was treated as a speculative, academic sub-discipline. That era has ended. Driven by accelerating climate impacts, private capital is flooding the sector.
- In 2024, US-Israeli startup Stardust Solutions secured $60 million in venture funding.
- In May, Stardust unveiled proprietary deployment systems designed to precisely regulate global temperatures on demand.
- In August, tech billionaire Elon Musk threw his considerable influence behind the concept, writing on social media platform X: "Space satellites to control temperature and massive geo-engineering will be needed or it will be game over."
Cynthia Scharf, a former UN advisor who participated in the war game, warns that governance decisions are rushing toward policymakers far faster than anticipated: "It’s not 15 years from now; it’s in the next decade, easily."
Official Statements and Policy Shifts
The fictional anxieties explored in Queen Mary University’s war room are already manifesting in the real-world halls of power across Washington, London, and corporate boardrooms.

+-----------------------------------------------------------------------------------+The Push for "Weather Sovereignty"
In early 2026, a series of policy papers published by conservative US think tanks explicitly urged the incoming Trump administration to seize leadership in solar radiation modification to counter perceived technological encirclement by China. One notable memorandum introduced a newly coined, nationalist framing: "Weather sovereignty."
Official UK Policy Stance
In the United Kingdom, the Ministry of Defense commissioned specialized security consultancies to analyze sunlight-reflection dynamics. Shortly thereafter, the British government released its inaugural official policy paper on SRM. While the framework greenlights controlled scientific research, it draws a rigid boundary against deployment, stating explicitly that the UK does not support and "does not plan to do so."
Private Sector Perspectives
Corporate actors developing these technologies harbor no illusions regarding international realpolitik. Yanai Yedvab, CEO of Stardust Solutions, acknowledges that national security dynamics will inevitably dictate how the technology is handled.
"We are developing a very powerful tool," Yedvab noted in an interview with WIRED. "When you develop this kind of powerful technology—and you have many precedents—national interests will play out. We’re not naive about it."
Stardust maintains that it will refrain from large-scale outdoor testing or operational deployment until robust international governance frameworks are established. However, Yedvab observes that diplomatic engagement is accelerating because "the majority of policymakers […] are already aware of this technology."
Future Outlook: Personal Retreat vs. Planetary Reality
The convergence of failing global climate mitigation, soaring energy costs, and escalating ecological disasters creates a volatile breeding ground for unilateral geoengineering. During the exact timeframe of the London war game, international efforts to curb fossil fuel consumption suffered severe setbacks amidst political backlash and chronic heatwaves across Europe. In late August, the catastrophic collapse of a Himalayan glacier along the Tibet-Nepal border claimed over 1,450 lives—a tragic realization of decades-old scientific warnings.
For Colleen Golja, the simulation served as a profound psychological turning point. Disillusioned by the realization that global superpowers will likely navigate existential climate threats through the prism of narrow self-interest, espionage, and strategic rivalry rather than empirical reason, she has fundamentally redirected her career.
Pinned to the corkboard behind her desk is a handwritten note outlining a new ethos for a world governed by geopolitical realpolitik rather than scientific stewardship. Golja plans to leave behind the frustrating arena of global policy debates and return to her small coastal hometown in Connecticut. There, she intends to apply her technical expertise directly to local climate resilience initiatives—helping municipal groups construct seawalls and coastal erosion buffers to safeguard her immediate community against inevitable environmental shocks.
"To try and make a difference where it feels like I actually have traction," Golja reflects. After witnessing firsthand how easily scientific truth can be corrupted and sidelined by the machinery of state power, pursuing global climate governance lost its appeal. In an era where superpowers eye each other across an atmospheric precipice, Golja’s struggle—and humanity’s collective dilemma—has become intensely, unavoidably personal.
