他们模拟了给太阳降温，结果比想象中更糟
They war-gamed dimming the Sun. It went even worse than you think.
气候研究员 Colleen Golja 参与了一场模拟地缘政治博弈，探讨如何避免各方不受控地竞相开发旨在冷却地球、但风险未知的技术。名为“探索地缘政治临界点与气候冷却策略”的模拟在伦敦玛丽女王大学举行，参与者包括外交事务专家、科学家、军方人员和前政府官员。
When it comes to deciding the fate of the planet, Colleen Golja always thought science and reason would have a seat at the table. That was until one morning last September in London, when the climate researcher took part in the first in a series of war games. The goal: to prevent an uncontrolled global race to develop a technology aimed at cooling the planet but that comes with vast, unknown risks that could reshape life on Earth.
“I thought that would be such an easy thing. Like, we can all agree to do ethical research and make sure it's for the better of all humans,” she told WIRED. “And boy, was I wrong.”
The simulation, titled Exploring Geopolitical Tipping Points and Climate Cooling Strategies, saw a couple dozen foreign-relations experts, scientists, military personnel, and former government officials from across the world convene in a meeting room at Queen Mary University of London. After making introductions over coffee and little yogurts, they sat at tables arranged in a square with the name of the country or organization each person was playing: national governments, climate NGOs and nonprofits, indigenous groups, and tech companies. Golja was assigned to provide technical advice to help participants make scientifically literate decisions.
