Disproportionate Sequestration
Coastal ecosystems cover less than 2% of total ocean area, yet account for nearly half of the total carbon sequestered in ocean sediments. Mangroves alone can store up to four times more carbon per hectare than tropical rainforests.

Data & Modeling
| Ecosystem | Global Area (Mha) | Carbon Burial Rate (Tg C/yr) |
|---|---|---|
| Mangroves | 13.8 - 15.2 | 24 - 40 |
| Salt Marshes | 2.2 - 40 | 14 - 87 |
| Seagrasses | 17.7 - 60 | 48 - 112 |
Common Misconceptions
A frequent error in media interpretation is confusing localized transient effects with global secular trends. The figures demonstrated here isolate the multi-decadal signal from seasonal noise.
Frequently Asked Questions
Is this reversible?
On human timescales, highly unlikely. The thermal inertia of the ocean means impacts will persist for centuries even if emissions cease immediately.
How accurate are these figures?
Based on the latest AR6 synthesis and prevailing primary literature. Uncertainties are inherent in coupled non-linear climate models.
