The SPICE project sought to investigate whether a balloon could be an affordable option for dispensing sunlight-reflecting particles into the sky. Illustrations by Dylan Glynn.
[font size=3] The scientists had whipped themselves into a frenzy. Gathered in a stuffy conference room in the bowels of a hotel in Berlin, scores of respected climate researchers, mostly middle-aged, mostly white, and mostly men, were arguing about a one-page document that had tentatively been christened the
Berlin Declaration. It proposed ground rules for conducting experiments to explore how we might artificially cool the Earthplanet hacking, basically.
Its most commonly called
geoengineering. Think Bond-villain-caliber schemes but with better intentions. Its a highly controversial field that studies ideas like
launching high-flying jets to dust the skies with sulfur in order to block out a small fraction of the solar rays entering the atmosphere, or sending a fleet of drones across the ocean to spray seawater into clouds to
make them brighter and thus reflect more sunlight.
Those are two of the most discussed proposals for using technology to chill the planet and combat climate change, and each would ostensibly cost a few billion dollars a yearpeanuts in the scheme of the global economy. Were about to see the dawn of the first real-world experiments designed to test ideas like these, but first, the scientists wanted to agree on a code of ethicshow to move forward without alarming the public or breaking any laws.
An engineer stepped up to the mic and said that there was no need to regulate any climatically trivial experiments in the field. Another disagreed. The only trivial real-world geoengineering experiment yet attempted, he said, had caused very grave social considerations. So apologies, Andrew, but youre talking nonsense. The room buzzed with stifled laughter.
