Sea Level Rise Risks for Mangrove Carbon Sinks

Mangroves serve as highly efficient carbon sinks, trapping significant amounts of carbon in their biomass and soil. However, new research indicates that rising sea levels could drown these ecosystems, potentially reversing their role and releasing stored carbon back into the atmosphere. Understanding the stability of these coastal ecosystems is critical for accurate carbon accounting and the long term viability of nature based climate solutions.

This highlights a major issue with permanence in nature based offsets. If the carbon sink drowns and releases emissions, the original credit is effectively void. We need better accounting for these climate risks.

Exactly. Most projects just look at the planting phase. They rarely account for the 50 year risk of sea level rise in the actual baseline.

The link to the full study mentions the University of Exeter. It would be useful to see the specific rate of sea level rise that triggers this tipping point for different mangrove species.
