What’s a ‘super El Niño’? And other El Niño questions, answered

We get into it: Why some meteorologists don't like the term 'super El Niño,' why climate change can lead to El Niño surprises, and more. The post What’s a ‘super El Niño’? And other El Niño questions, answered appeared first on Yale Climate Connections.

Abatify Summary

**Super El Niño events exacerbate climate volatility, directly threatening the permanence of LULUCF-based carbon sequestration and increasing catastrophic wildfire risks.** - Intensified El Niño cycles lead to severe droughts in key tropical regions, compromising the health of biodiversity hotspots and accelerating forest dieback. - Marine heatwaves associated with peak ocean temperatures disrupt Blue Carbon ecosystems, specifically sea grasses and mangroves, which are critical for high-density carbon storage. - Extreme weather fluctuations undermine long-term environmental stability, making it difficult for nature-based projects to meet ICVCM benchmarks for additionality and permanence.

**The intensification of El Niño cycles introduces significant price volatility into the voluntary carbon market (VCM) by triggering reversal mechanisms and challenging ICVCM Core Carbon Principle (CCP) permanence standards.** - Physical climate risks from 'super' events force a re-evaluation of buffer pool adequacy for Article 6.4 credits, potentially leading to higher insurance premiums for developers. - Disruptions to agricultural yields and logistics create Scope 3 reporting challenges for corporations, as supply chain resilience is tested by extreme meteorological shifts. - Financial liquidity in the climate market may shift toward Technical removals over Nature-Based solutions as investors seek assets with lower exposure to immediate climate-driven reversal risks.
