Adaptation vs. Mitigation
The critical distinction between reducing the causes of climate change and preparing for its impacts, and why the world needs both strategies simultaneously.
Two Complementary Strategies
Climate mitigation means reducing greenhouse gas emissions to slow or stop global warming. This includes transitioning from fossil fuels to renewable energy, improving energy efficiency, protecting forests, and changing agricultural practices. Mitigation addresses the root cause of climate change. Climate adaptation means adjusting to the impacts of climate change that are already occurring or are inevitable. This includes building sea walls, developing drought-resistant crops, redesigning cities for extreme heat, and creating early warning systems for extreme weather.
For years, the climate community prioritized mitigation. The logic was understandable: talking about adaptation could imply acceptance of failure to prevent warming. Some worried that investing in adaptation would reduce the urgency to cut emissions. But as climate impacts have accelerated, it has become clear that adaptation is not optional. Even if all emissions stopped today, the warming already locked into the climate system would continue to cause impacts for decades. Both strategies are essential.
