Thematic Evidence Discovery
Climate Evidence Themes
Search climate evidence by environmental system, risk question or implementation challenge. The universal map places these themes beside country, regional, local-area, indicator, date and rendering controls.

Select a theme to review its scope, evidence pathway and implementation status, or use the same selector after choosing any available administrative area in the live map.
Indicator evidenceGlobal Temperature and Emissions Trends
Track observed warming, greenhouse-gas emissions, sectoral patterns, national trajectories and the relationship between current trends and long-term climate goals.
- Temperature records and anomalies
- Global and national emissions inventories
- Per-capita, sectoral and historical perspectives
- Trend interpretation and uncertainty
Live NDVI indicatorForests and Land-Cover Change
Explore forest condition, vegetation cover, degradation, recovery, land conversion and restoration signals using globally selectable administrative boundaries, satellite imagery, classifications and field evidence.
- Operational Sentinel-2 NDVI visualization
- Natural-colour landscape context
- Future forest and land-cover classification
- Field verification for causal claims
Live universal pilotWater Stress and Drought
Inspect moisture and vegetation response through Sentinel-2 NDMI and NDVI for any sufficiently focused selected administrative polygon, while separating satellite signals from a complete drought or water-access assessment.
- Worldwide country, ADM1 and ADM2 selection
- NDMI moisture-condition colour layer and legend
- NDVI vegetation-condition supporting layer
- Rainfall, water balance, hydrology and field evidence still required
Thematic layer pathwayWildfires and Burned Areas
Connect fire occurrence, burned-area evidence, vegetation recovery, drought conditions and local preparedness while distinguishing observation from emergency warning.
- Active-fire and burned-area datasets
- Pre-fire and post-fire imagery
- Recovery and vegetation-condition monitoring
- Preparedness and local verification
Live map contextBiodiversity and Ecosystem Condition
Assess habitat condition, vegetation structure, ecosystem productivity, fragmentation and nature-based resilience through remote sensing, official biodiversity evidence and field knowledge.
- Vegetation and habitat context
- Fragmentation and landscape connectivity
- Ecosystem productivity and stress
- Species and field evidence where appropriate
Thematic layer pathwayGlaciers, Snow and Mountain Systems
Explore snow cover, glacier condition, mountain climate, elevation, upstream-downstream water connections and the exposure of highland and downstream communities.
- Snow and ice observations
- Elevation, slope and mountain geography
- Seasonal and historical imagery
- Water and hazard linkages
Risk evidenceClimate Hazards and Vulnerability
Connect hazards with exposure, sensitivity, adaptive capacity and institutional readiness without presenting contextual imagery as an operational warning system.
- Heat, flood, drought, fire and landslide context
- Population, infrastructure and ecosystem exposure
- Vulnerability and adaptive-capacity indicators
- Preparedness, early warning and response systems
Policy evidenceInternational Climate Commitments and Implementation
Review climate commitments, national plans, adaptation priorities, finance, transparency and implementation progress alongside environmental outcomes.
- Paris Agreement and national commitments
- NDCs, adaptation plans and long-term strategies
- Climate finance and implementation capacity
- Monitoring, reporting and accountability
Evidence discipline: NDMI and NDVI are operational satellite indicators across sufficiently focused selected administrative areas, but they do not replace rainfall, water-balance, hydrological, biodiversity, vulnerability, emissions or policy datasets. Boundaries and evidence sources are labelled separately.
