Rich Sutton's 2019 essay "The Bitter Lesson" argues that AI research consistently proves scaling raw computing power outperforms human-designed clever approaches. This insight parallels climate adaptation strategy in a counterintuitive way.

Climate advocates often frame adaptation as defeat, a capitulation to warming we failed to prevent. The argument treats mitigation—reducing emissions—as the only acceptable response. Adaptation gets dismissed as giving up on the core problem.

This framing mistakes the nature of climate reality. We face two distinct challenges: preventing future warming through emission cuts, and managing current and near-term warming that locks in regardless of immediate action. Physics already built decades of warming into the climate system. Even aggressive mitigation today cannot erase it.

The "bitter lesson" from decades of climate science tells us something similar to AI research's core finding. Brute-force adaptation strategies—building seawalls, developing drought-resistant crops, relocating communities, upgrading infrastructure—often prove more effective than hoping carbon pricing alone solves everything. Massive infrastructure investment in climate resilience works. Clever policy designs without sufficient resources frequently fail.

This does not negate the need for mitigation. Cutting emissions remains essential to prevent catastrophic long-term warming. But treating adaptation as surrender misreads the actual challenge. Societies that prepare for coming heat, water stress, and extreme weather will protect lives and economies better than those betting exclusively on mitigation.

The political debate often forces a false choice. Adaptation becomes the conservative position, mitigation the progressive one. In reality, both operate simultaneously in any functional climate response. Countries like Bangladesh spend heavily on adaptation despite minimal historical emissions. Australia faces adaptation demands while debating mitigation policies. These aren't competing priorities but complementary necessities.

Scaling up adaptation investment requires resources, political will, and long-term planning. It means building redundancy into food
