Analysis: ‘Super El Niño’ reaches ‘remarkable’ all-time record

Nature & Climate Perspective

**Record-shattering Super El Niño conditions significantly elevate catastrophic reversal risks across terrestrial and marine carbon sinks, directly testing the permanence threshold demanded by the ICVCM Core Carbon Principles. **

• Thermal anomalies in the tropical Pacific trigger widespread coral bleaching, threatening coastal marine biodiversity and degrading the carbon burial capacity of linked Blue Carbon ecosystems.
• Severe drought regimes exacerbated by ENSO suppress photosynthetic uptake and accelerate biomass decay across global LULUCF systems, notably in the Amazon and Southeast Asia.
• Elevated wildfire susceptibility and aridification challenge the ecological stability of nature-based buffer pools, testing whether existing reversal mechanisms conform to the ICVCM CCP on permanence and risk mitigation.

Market & Policy Outlook

**Intensified climate extremes expose physical vulnerabilities in voluntary and compliance markets, jeopardizing corporate decarbonization trajectories and sovereign credit transfers. **

• Unprecedented natural disturbances disrupt host-nation carbon accounting, threatening baseline assumptions and corresponding adjustments for ITMOs under Article 6.2 and Article 6.4 mechanisms.
• Heightened risk of physical reversals forces carbon registries to expand required buffer pool contributions, increasing compliance costs and constricting liquidity for CCP-labeled forestry credits.
• Corporations leveraging natural climate solutions for Scope 3 emissions mitigation or SBTi-aligned beyond-value-chain mitigation face reputational and audit vulnerabilities as credit deliverability and sink integrity deteriorate.
