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.

Indicator evidence

Global 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 indicator

Forests 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

Water 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 pathway

Wildfires 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 context

Biodiversity 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 pathway

Glaciers, 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 evidence

Climate 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 evidence

International 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.
