Bomb the Arctic, dam the Mediterranean and build a second moon: five outlandish plans to remodel our climate

Geoengineering the Earth’s climate has long been a topic of wild speculation, with ideas ranging from bombing the Arctic to create ice to building a second moon. As the climate crisis worsens, some scientists are seriously considering these extreme measures, hoping they might mitigate the worst effects of global warming. Proposals like cloud brightening and injecting sulphur into the atmosphere aim to reflect sunlight away from the planet. While these plans sound outlandish, they highlight the desperation and urgency felt by some in the face of escalating environmental catastrophes. The debate over geoengineering underscores the tension between traditional environmentalism and the need for radical, potentially risky interventions.
