The summer of 2026 has brought a stark reminder of the reality of climate change: adaptation is not surrender, but a necessity for survival. The smoke from Canadian wildfires, exacerbated by climate change, has reached the air of 120 million Americans, highlighting the urgent need for adaptation measures. This is not an isolated incident; it is a pattern of increasing wildfires, heat waves, and smoke events that are becoming more frequent and severe. The question is: how can we adapt to these disasters when our current emissions policies and efforts are insufficient?
The AI researcher Rich Sutton's essay, 'The Bitter Lesson', provides a relevant framework for understanding this challenge. Sutton argues that the most effective way to train AI is through raw, brute-force computing power, rather than relying on human insight. This lesson applies to climate change as well. Despite our efforts, the current approach of reducing emissions may not be enough to protect us from the present-day effects of climate change. The smoke from Canadian wildfires, for example, cannot be prevented by American mitigation efforts, and the air quality alerts issued across 18 states are a stark reminder of this.
The Exceptional Events Rule under the Clean Air Act acknowledges the futility of trying to stop wildfire smoke. Instead, it suggests deleting it from the air quality record. This is a bitter lesson, as it implies that our best efforts may not be enough to prevent the worst-case scenarios. The smoke is particularly dangerous due to its microscopic particles, which are three to four times more toxic to the lungs than ordinary urban particulate matter. Pediatric asthma visits spike during major smoke events, and the cardiorespiratory damage persists for months.
However, adaptation is not an impossible task. Technologies exist to protect ourselves, such as the Corsi-Rosenthal box, which can purify indoor air and reduce fine particles by half. Similarly, the national heat plan in France, which includes tiered alerts, registries of vulnerable residents, and cool rooms, has significantly reduced the death toll during heat waves. These measures are saving lives, but they are not being implemented widely enough.
Some governments are ahead of the game, such as Washington state, Oregon, and California, which regulate outdoor workers' smoke exposure and provide clean air centers and free HEPA units to classrooms. However, many regions are not taking climate change seriously enough. The lack of enforceable national indoor air-quality standards in the US and the reluctance of European countries to adopt air conditioning are examples of this. These regions need to catch up and prioritize adaptation measures.
The caution around adaptation, often seen as a delaying tactic, has shifted as the projections have come true. Longer fire seasons, deadlier heat waves, and smoke reaching new areas are no longer just warnings but realities. Climate change is no longer a distant threat but a present-day challenge. The seriousness of the situation requires us to treat adaptation as a priority, not a distraction. As Sutton's lesson suggests, accepting the bitter lesson is the first step towards building what works and ensuring our survival in a changing climate.
