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 ...
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.
The World Meteorological Organisation’s (WMO) annual bulletin shows the three main greenhouse gases – carbon dioxide, methane and nitrous oxide – all reached record high concentrations in ...
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.
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]
In 2017, it was discovered that 40% of the Cuvette Centrale wetlands are underlain with a dense layer of peat, which contains around 30 petagrams (billions of tons) of carbon. This amounts to 28% of all tropical peat carbon, equivalent to the carbon contained in all the forests of the Congo Basin.
A research team made a worrisome discovery off the Siberian coast, The Guardian reports. The scientists say they believe they are first to uncover observational evidence that frozen methane ...
