Wetlands play a crucial role in the exchange of greenhouse gases with the atmosphere, affecting global climate. Older wetlands can have a cooling effect due to the accumulation of soil carbon over time. Disturbances to wetlands can lead to long-lasting warming effects, even after restoration. It is important to avoid activities that disturb wetlands and cause the release of stored carbon to protect their climate-regulating function. Wetlands provide various ecosystem services, so management plans should consider all aspects when creating, restoring, or protecting wetlands.
