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.
Some wetlands are a significant source of methane emissions [6] [7] and some are also emitters of nitrous oxide. [8] [9] Nitrous oxide is a greenhouse gas with a global warming potential 300 times that of carbon dioxide and is the dominant ozone-depleting substance emitted in the 21st century. [10] Wetlands can also act as a sink for greenhouse ...
Methane clathrate, also known commonly as methane hydrate, is a form of water ice that contains a large amount of methane within its crystal structure. Potentially large deposits of methane clathrate have been found under sediments on the ocean floors of the Earth, although the estimates of total resource size given by various experts differ by ...
Methane's GWP 20 of 85 means that a ton of CH 4 emitted into the atmosphere creates approximately 85 times the atmospheric warming as a ton of CO 2 over a period of 20 years. [23] On a 100-year timescale, methane's GWP 100 is in the range of 28–34. Methane emissions are important as reducing them can buy time to tackle carbon emissions. [24] [25]
However, subtropical wetlands have shown high CO 2 binding per mol of released methane, which is a function that counteracts global warming. [39] Tropical peatlands are suggested to contain about 100 Gt carbon, [40] [30] corresponding to more than 50% of the carbon present as CO 2 in the atmosphere. [2]
The study suggested that tropical wetland methane emissions were the culprit behind the recent growth trend, and this hypothesis was reinforced by a 2022 paper connecting tropical terrestrial emissions to 80% of the global atmospheric methane trends between 2010 and 2019. [14]

A methane gas and dust explosion resulted in the deaths of 195 men. [4] [5] The New London School explosion occurred on March 18, 1937, when a natural gas leak caused an explosion, destroying the New London School of the city of New London, Texas. The disaster killed three hundred students and teachers.
