  • Global emissions of methane have reached the highest levels on record. Increases are being driven primarily by growth of emissions from coal mining, oil and natural gas production, cattle and sheep ranching, and landfills.
  • The concentration of methane in the atmosphere has risen sharply -by about 25 teragrams per year - since 2006. In recent years, different research teams have come up with viable but conflicting explanations for the increase. Some teams have published evidence showing that emissions from biogenic sources is driving the increase.

Atmospheric methane levels have been rising, so Worden and colleagues applied some new analyses of satellite and ground-based data to more accurately pinpoint the sources. The concentration of methane in the atmosphere has risen sharply —by about 25 teragrams per year — since 2006. In recent years, different research teams have come up with viable but conflicting explanations for the increase.

First, the recent methane surge into the atmosphere is due not to the rising fossil-fuel emissions, but rather to an unexpected surge in microbial sources. Second, fossil-fuel sources are — and have been for at least some decades — almost twice as big as previous estimates, whereas microbial sources are about a quarter less.

For more than two centuries, rising methane emissions have resulted in steady increases in the concentration of the gas in the atmosphere.

If that process has slowed down—causing methane to build up in the atmosphere—it would leave more light gas behind, possibly helping explain the overall trend.

About 40% of methane comes from natural sources (wetlands and natural wildfires), while 60% comes from anthropogenic sources (agriculture, waste treatment, coal mine seeps, and oil/gas production). Fossil-fuel methane emissions account for roughly 34% of the anthropogenic emissions.

Over a 20-year time frame, methane traps 86 times as much heat in the atmosphere as carbon dioxide. It is responsible for about a quarter of total atmospheric warming to date. And while the steady...
