It starts with a rain barrel, a shaded courtyard, a sidewalk sponge. Welcome to our Signals: short dispatches on everyday climate adaptation, from Dresden to Delhi to Denver.
This living collection highlights products, projects, and practices from around the world that reflect the next steps in climate adaptation, whether cutting edge, rediscovered, or simply well implemented.

For centuries, buildings stayed cool by using natural physical forces like reflection, shading, and air circulation.
As heat stress rises and cities and communities adapt, it is becoming clear that energy-intensive technology is not the best answer.
The global transition from air-conditioning dependence to climate intelligence marks a wider cultural shift in how we plan, invest, and care for our built environments.
LocationHealth supports this shift by making adaptive solutions visible, comparable, and actionable, defining a new generation of practical, scalable measures for living in a hotter world.
→ For years, urban planners have debated green versus grey. But the climate doesn’t care about that divide, and neither can cities.
Recent studies show why: during extreme rainfall, purely vegetated systems lose hydraulic performance as soils saturate and infiltration stops.
By contrast, hybrid drainage - vegetation paired with engineered subdrains or controlled outlets - retains up to 80% efficiency even under peak storm intensity (Water, 2024).
Across case studies, these systems cut runoff peaks by 60%, lower surface temperatures by 2–4°C, and reduce lifecycle costs by around 25% compared with conventional infrastructure (World Bank 2023; Zhu et al. 2025).
It is no longer a question of choosing sides.
The future is nature first, engineered where needed - a pragmatic evolution that makes resilience measurable, maintainable, and finally scalable.
