A new global map reveals how salt marshes act as vital carbon sinks
High-resolution satellite mapping shows that Earth's salt marshes store massive amounts of carbon within their soil, providing a natural defense against climate change that is far more efficient than terrestrial forests.
A groundbreaking global map has revealed that salt marshes are powerhouse carbon sinks, sequestering carbon at rates up to 50 times faster than tropical rainforests. These coastal wetlands trap organic matter in waterlogged soils where lack of oxygen prevents decomposition, locking away carbon for centuries.
