In a small fishing village on the Mekong Delta, elders will tell you that the tides are “acting strangely.” They speak of water creeping farther inland than in their parents’ time, and of storm seasons that come earlier, with winds that feel “hungrier.” These observations are rich in detail, yet when plotted against the outputs of regional climate models, the timelines don’t quite match.
This is not an isolated disconnect. Across the world, from Arctic Inuit communities to Andean farmers, local knowledge sometimes diverges from what climate scientists’ models predict. At first glance, it can feel like a contradiction—one worldview built from lived experience, the other from equations. In truth, it’s more like two overlapping photographs: each capturing part of the same scene, each slightly out of alignment.
The Language of Models
Climate models are sophisticated tools, built from millions of data points and decades of atmospheric physics. They are designed to capture large-scale patterns: how ocean currents shift, how heat is redistributed, how ice sheets melt. But their strength—the ability to look at the planet as a whole—can also be a limitation. The resolution is often too coarse to fully capture hyperlocal variations in wind patterns, soil moisture, or microclimates shaped by topography.
Imagine forecasting the flavor of a stew by averaging the ingredients in the pot. You’ll get the general profile right, but you might miss that one corner where the spices concentrate, or another where the broth is thinner. Local conditions can be that “corner of the pot”—a place where general trends bend under the weight of geography.
The Knowledge of Place
Local knowledge is built differently: through decades or even centuries of careful observation, passed down orally, often embedded in cultural practices. It can spot anomalies faster than satellites, especially in places where scientific instruments are sparse. An Inuit hunter can tell from the sound of sea ice underfoot whether a thaw will come sooner than expected; a farmer in the Sahel can read a shift in wind direction as a cue for planting earlier or later.
But local knowledge, too, has its blind spots. Extreme events that fall far outside the historical memory of a community—like unprecedented floods or heatwaves—can be underestimated simply because they haven’t been seen before.
Toward a Shared Map of the Future
The challenge isn’t to decide which perspective is “right,” but to integrate them. Some promising initiatives already do this. In the Pacific Islands, scientists are working with traditional navigators to calibrate seasonal cyclone forecasts. In the Amazon, hydrologists combine indigenous flood markers carved into riverbank trees with satellite rainfall data to improve warning systems.
These collaborations work best when both sides treat their counterpart not as an informant, but as a fellow expert. The scientist brings a telescope; the local observer brings a magnifying glass. Together, the picture sharpens.
Why It Matters Now
Climate change is not just a planetary shift—it is lived locally. Policies shaped only by models risk missing the nuances that make adaptation possible. Conversely, strategies built only on local memory may falter against the unprecedented speed and scale of change.
Bridging the two is more than a technical exercise—it’s a form of respect. It acknowledges that solving the climate crisis requires both the view from space and the view from the village square.
