Climate Change Data
A practical weather-data lens on warming, heavy rainfall, drought, and urban risk.
Climate change data combines long-term observations with near-real-time weather monitoring. WeatherIndex treats climate context as background information, while city pages remain driven by live forecast APIs.
Data points to watch
- Temperature anomalies against a historical baseline.
- Frequency and duration of heat waves in major cities.
- Extreme rainfall intensity and drought persistence.
How to use it
Use climate data for trend awareness and risk planning, then use local forecasts for daily decisions.
