Methane is a potent greenhouse gas that is 25 times more effective at trapping heat in the atmosphere than carbon dioxide. It is also the second most prevalent greenhouse gas after carbon dioxide.
The primary sources of methane emissions are natural wetlands, agriculture, landfills, and fossil fuel extraction and transportation. However, a new study published in the journal Nature suggests that wetlands and agriculture could be responsible for a larger share of methane emissions than previously thought.
The study, led by researchers at the University of California, Berkeley, used a new method to estimate methane emissions from wetlands and agriculture. The method combines satellite data with ground-based measurements to provide a more accurate estimate of methane emissions from these sources.
The study found that wetlands and agriculture are responsible for 60% of global methane emissions, while fossil fuel emissions account for only 40%. This is a significant departure from the previous estimate, which suggested that fossil fuels were responsible for 60% of global methane emissions.
The study's findings have important implications for climate policy. If wetlands and agriculture are responsible for a larger share of methane emissions than previously thought, then it will be necessary to focus on reducing emissions from these sources in order to mitigate climate change.

There are a number of ways to reduce methane emissions from wetlands and agriculture. For example, farmers can reduce methane emissions from livestock by improving manure management practices and using feed additives that reduce methane production. Wetlands can also be managed to reduce methane emissions, such as by restoring degraded wetlands and reducing water levels in flooded areas.
By focusing on reducing methane emissions from wetlands and agriculture, we can help to mitigate climate change and protect the environment.
The new study provides strong evidence that wetlands and agriculture are responsible for a larger share of methane emissions than previously thought. This has important implications for climate policy, as it will be necessary to focus on reducing emissions from these sources in order to mitigate climate change.
