Has it been? How so?
This potent greenhouse gas has been ‘widely’ underestimated, study finds
Parts of the U.S. may be emitting much more of one of the most potent greenhouse gases than previously thought, according to new research.
Satellite observations suggest that methane emissions in urban areas may be “widely underestimated” – up to 80% higher than noted in the U.S. Environmental Protection Agency’s Greenhouse Gas Inventory, an annual report that accounts for total greenhouse gas emissions and carbon sinks for all man-made sources in the U.S., according to a paper published Wednesday in Science.
Researchers analyzed satellite images taken by the TROPOspheric Monitoring Instrument (TROPOMI) on the Sentinel-5P satellite and found that emissions from 12 major urban areas – New York City, Los Angeles, Chicago, Philadelphia, Dallas, Miami, Houston, Washington, D.C., Atlanta, Boston, Detroit and Cincinnati – were emitting up to 80% more methane than reported by the EPA, according to the study.
The finding suggests that urban sources of methane, such as landfills and natural gas infrastructure, play a larger role in near-term climate warming than previously realized, Xiaolin Wang, a postdoctoral researcher in atmospheric science at Harvard University and lead author of the paper, told ABC News.

Urban areas have complex, population-driven methane sources, including landfills, natural gas distribution systems, wastewater treatment plants and residential combustion, Wang said.
So, basically, urban areas which are dominated by Democrats who make up the vast amount of Warmists are horrible people who want to destroy the planet, burn it to a cinder? Huh. How about that!
Really, though, we’ve know about the problem with methane, especially as it relates to agriculture and landfills, for quite some time. This was a big focus of early IPCC reports, but, no one wanted to focus on it because 1) people will make lots of fart jokes and 2) unlike CO2, it couldn’t be fearmongered in a way to take away money, freedom, and life choices from people by The Government. You can’t force citizens to give up their fossil fuels and ride the bus over methane. Yammer about methane and people worry about being able to eat, hence why only the cultiest of culters talk about taking on the agriculture sector.

Methane is a more potent global warming chemical than CO2 but has a shorter residence time in the atmosphere.
Agriculture (Highest Human Source): Responsible for roughly 40% of anthropogenic (human-caused) methane, primarily through livestock digestion (burps from cows, sheep, and goats) and manure management. Rice cultivation is also a significant contributor.
Fossil Fuel Production & Use: The energy sector accounts for about 35% of human-caused methane. This includes leaks from oil and gas extraction, processing, and transportation (natural gas is mostly methane), as well as coal mining.
Waste Management: Landfills and wastewater treatment plants contribute about 20% of anthropogenic emissions as organic waste decomposes in oxygen-free environments.
Natural Sources: The largest natural source is wetlands, which account for roughly 20-30% of total global methane emissions. Other natural sources include termites, oceans, and thawing arctic permafrost.
Methane from thawing permafrost is a significant positive feedback. The warmer it gets, the more methane is released. Melting of the ice sheets and sea ice are also positive feedbacks by reducing the albedo. Do these feedbacks contribute to the increased rate of warming?
But relax. The Repubes led by your King Donald will not permit regulations to limit CO2 or methane. Young Prince JD also has your back!! If the Republicuns manage to rig the 2026 and 2028 elections you will be able to pollute to your hearts content!!! Carbon Forever!!!
