Scientists had long projected wetland methane emissions would rise as the climate warmed, but from 2020 to 2022, air samples showed the highest methane concentrations in the atmosphere since ...
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 ...
Most of the threats appear to have occurred at precincts in the Democratic-leaning Dekalb, Fulton and Gwinnett Counties.
The world saw a record jump in levels of methane in the atmosphere last year as the main heat-trapping greenhouse gases reached new highs, UN experts said. ... emissions from wetlands as a result ...
[109] [110] [111] Shakhova et al. (2008) estimate that not less than 1,400 gigatonnes of carbon is presently locked up as methane and methane hydrates under the Arctic submarine permafrost, and 5–10% of that area is subject to puncturing by open talik. Their paper initially included the line that the "release of up to 50 gigatonnes of ...
Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, [1] air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health.

Methane is a substantial source of energy in certain hydrothermal vents, but not others: methane is more abundant in warm vents (25 °C) than hydrogen. [11] Many types of methanotrophic bacteria exist, which require oxygen and fix CH 4 , CH 3 NH 2 , and other C 1 compounds, including CO 2 and CO, if present in vent water. [ 11 ]
