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.
A heat map of the planet showing methane emissions from wetlands from 1980 to 2021. Greenhouse gas emissions from wetlands of concern consist primarily of methane and nitrous oxide emissions. Wetlands are the largest natural source of atmospheric methane in the world, and are therefore a major area of concern with respect to climate change.
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.
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 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 ...
Mexico emitted "extreme" amounts of methane from a natural gas pipeline running through its northern border state Durango in 2019, a research paper published on Tuesday showed, citing data ...
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]
In the first two weeks of November, fires fueled by unusually dry and hot weather destroyed nearly 770,000 hectares (1.9 million acres) of the world’s largest tropical wetlands, preliminary ...
