Wetland restoration[ edit]
Wetlands are created when water overflows into heavily vegetated soil causing plants to adapt to a flooded ecosystem. Wetlands can occur in three different regions. Marine wetlands are found in shallow coastal areas, tidal wetlands are also coastal but are found farther inland, and non-tidal wetlands are found inland and have no affects from tides. Wetland soil is an important carbon sink; 14.5% of the world's soil carbon is found in wetlands, while only 5.5% of the world's land is composed of wetlands. Not only are wetlands a great carbon sink, they have many other benefits like collecting floodwater, filtering air and water pollutants, and creating a home for numerous birds, fish, insects, and plants.

Climate change could alter soil carbon storage changing it from a sink to a source. With rising temperatures comes an increase in greenhouse gasses from wetlands especially locations with permafrost. When this permafrost melts in increases the available oxygen and water in the soil. Because of this, bacteria in the soil would create large amounts of carbon dioxide and methane to be released into the atmosphere.

Peatlands hold aproximetly 30 perecent of the carbon in our ecosystem. When wetlands are drained for agriculture and urbanization, because peatlands are so vast, large quantities of carbon decompose and emit CO2 into the atmosphere. The loss of one peatland could potentially produce more carbon than 175-500 years of methane emissions.

While the link between climate change and wetlands is still not fully known, it will be soon determined through future removal of wetlands. It is also not clear how restored wetlands manage carbon while still being a contributing source of methane. However, preserving these areas would help prevent further release of carbon into the atmosphere.
