Countless forest-dwelling species depend on the cooler, moister and more stable conditions found in the understory, beneath leafy tree canopies.

Warming climate puts Southeast Asia’s forests near thermal limits: study
Abatify Summary
Nature & Climate Perspective
**Southeast Asia's forests nearing their thermal limit threatens the collapse of cooler understory microclimates, critically destabilizing local biodiversity and carbon sink permanence. **
- Microclimatic buffering within the understory is failing as canopy temperatures breach critical thresholds, endangering heat-sensitive endemic species.
- Accelerated thermal stress reduces the net carbon sequestration rate of tropical forests, converting historical carbon sinks into active emissions sources.
- The loss of moisture-retaining canopy structures disrupts local hydrological cycles, permanently degrading the ecological stability and wildfire resilience of the biome.
Market & Policy Outlook
**Thermal degradation of tropical forests poses severe integrity risks to LULUCF assets, directly challenging ICVCM Core Carbon Principle (CCP) permanence requirements. **
- Heightened reversal risks from thermal canopy collapse threaten the structural integrity of Article 6.2 and 6.4 ITMOs backed by tropical forestry.
- Carbon market pricing is expected to discount Southeast Asian forestry credits as buffer pools face unprecedented depletion due to climate-driven dieback.
- Corporate buyers aiming for SBTi verification face increased compliance risks, driving a market shift from avoidance-based LULUCF credits toward high-permanence technical removals to meet Scope 3 targets.
