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 ...
[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 ...
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 ...
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.
That's because methane's biggest emissions comes from wetlands, which during a La Nina is wetter in much of the tropics, creating more microbes in the lush growth to release methane, Lan said.
A carbon bomb, or climate bomb, [34] is any new extraction of hydrocarbons from underground whose potential greenhouse gas emissions exceed 1 billion tonnes of CO 2 worldwide. In 2022, a study showed that there are 425 fossil fuel extraction projects (coal, oil and gas) with potential CO2 emissions of more than 1 billion tonnes worldwide.
In Fulton County, Ga., officials said they received bomb threats at 32 of the 177 polling places, resulting in brief closures at five of them. In Indiana, text messages sent to voters falsely ...
