Planetary Engineering: The Most Neglected Lever on Climate?

Climate change receives a lot of attention, but the concept of deliberately engineering our planet to counteract its effects remains largely overlooked. 🌡️ Techniques like solar radiation modification (SRM)—which involves injecting aerosols into the stratosphere or brightening marine clouds—could potentially offset a significant portion of global warming in just a few years at a cost of billions rather than trillions. Other methods, such as ocean iron fertilization and enhanced rock weathering, also offer promising avenues for carbon drawdown.

However, these solutions come with great risks. The affordability of SRM means that a single nation or individual could implement it without global consensus, leading to serious repercussions for everyone—a classic example of the "free driver" problem. Governance structures are woefully inadequate, raising parallels to the challenges seen in advanced AI development, where technological capacity is outstripping oversight.
