Wetlands can act as a sink or a source of carbon, depending on the specific wetland. If they function as a carbon sink, they can help with climate change mitigation. However, wetlands can also be a significant source of methane emissions due to anaerobic decomposition of soaked detritus, and some are also emitters of nitrous oxide. [8] [9]
BAKU (Reuters) -The world's warming tropical wetlands are releasing more methane than ever before, research shows — an alarming sign that the world's climate goals are slipping further out of reach.
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 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 ...
The Wetlands Geodatabase and the Wetlands Mapper, as an Internet discovery portal, provide technological tools that allow the integration of large relational databases with spatial information and map-like displays. The information is made available to an array of federal, state, tribal, and local governments and the public.
Climate change is worsening this uncertainty. Nearly 16% of the population here is aged one to nine. "We've always co-existed with water, unaware of the dangers, until tragedy strikes," says ...
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 .
Wetlands make up about 5-8% of Earth's terrestrial land surface but contain about 20-30% of the planet's 2500 Gt soil carbon stores. [49] Peatlands contain the highest amounts of soil organic carbon of all wetland types. [50] Wetlands can become sources of carbon, rather than sinks, as the decomposition occurring within the ecosystem emits ...
