Data published in March 2023 in Nature Climate Change shows that annual wetland emissions over the past two decades were about 500,000 tonnes per year higher than what scientists had projected ...
Wetlands are the largest natural source of atmospheric methane in the world, and are therefore a major area of concern with respect to climate change. [1] [2] [3] Wetlands account for approximately 20–30% of atmospheric methane through emissions from soils and plants, and contribute an approximate average of 161 Tg of methane to the ...
Studies have favorably identified the potential for coastal wetlands (also called blue carbon ecosystems) to provide some degree of climate change mitigation in two ways: by conservation, reducing the greenhouse gas emissions arising from the loss and degradation of such habitats, and by restoration, to increase carbon dioxide drawdown and its ...
It is a good way to reduce climate change. [56] Wetland soil, particularly in coastal wetlands such as mangroves, sea grasses, and salt marshes, [56] is an important carbon reservoir; 20–30% of the world's soil carbon is found in wetlands, while only 5–8% of the world's land is composed of wetlands.

According to UN Climate Change News, wetlands are disappearing three times faster than forests. Wetlands are facing growing threats that put their health at risk. Urban development, pollution, land drainage, and climate change are endangering these valuable habitats that serve as essential flood buffers and wildlife havens. [14]
Climate change mitigation policies can have a large and complex impact on the socio-economic status of individuals and countries This can be both positive and negative. [299] It is important to design policies well and make them inclusive. Otherwise climate change mitigation measures can impose higher financial costs on poor households. [300]
Deforestation is a primary contributor to climate change, [1] [2] and climate change affects the health of forests. [3] Land use change , especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels .
The effects of climate change on the water cycle are profound and have been described as an intensification or a strengthening of the water cycle (also called hydrologic cycle). [2]: 1079 This effect has been observed since at least 1980. [2]: 1079 One example is when heavy rain events become even stronger.
