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 ...
Wetland vary widely in their salinity levels, climate zones, and surrounding geography and play a crucial role in maintaining biodiversity, ecosystem services, and support human communities. [1] Wetlands cover at least six percent of the Earth and have become a focal issue for conservation due to the ecosystem services they provide.
Wetlands exist on every continent, except Antarctica. [19] The water in wetlands is either freshwater, brackish or saltwater. [18] The main types of wetland are defined based on the dominant plants and the source of the water. For example, marshes are wetlands dominated by emergent herbaceous vegetation such as reeds, cattails and sedges.
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
A wetland is a land area that is saturated with water, either permanently or seasonally, such that it takes on the characteristics of a distinct ecosystem. The primary factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation of aquatic plants , adapted to the unique hydric soil .
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 ...
A heat map of the planet showing methane emissions from wetlands from 1980 to 2021. Greenhouse gas emissions from wetlands of concern consist primarily of methane and nitrous oxide emissions. 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.
Climate change is not the only danger to Tunisia's wetlands, he said. Cities and towns are growing closer to the edges of lagoons and rubble and waste are ever more often dumped in or near the water.
