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 ...
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.
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]
The rule creates a methane tax and targets the U.S. oil and natural gas industry. Texas produces the greatest volume of petroleum and marketed natural gas and would likely be disproportionately ...
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.
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 ...
