Interesting article, and the outcome is reasonably known that fossil fuel emissions and natural/biogenic emissions play a role in methane emissions. This article captures the magnitude of emissions, and that makes it interesting.

Methane emissions from natural gas wells being a great concern was brought out by our founder years back, while discussing ways to address climate changes. To further along on this topic, here is our Founder's take:

In terms of the extent of emissions, this particular article appears to present the recent trends, but literature suggest that fossil fuel based methane emissions has been on rise for the last 150 years.

Moreover, unlike human based emissions, natural emissions from wetlands, and oceans tend to have a sink to certain extent, and historical data suggests that methane emissions were in balance until the planet started seeing extensive use of fossil fuels . For that matter, there were more wetlands, and rice paddies 150 years back compared to now.

With wetlands decreasing over time due to human expansion, which in a way should have decreased methane emissions, but that, most probably, gets superseded by non-natural emissions.

Methane is a greenhouse gas. It absorbs the sun’s heat and helps warm Earth’s atmosphere. The amount of methane in Earth’s air has sharply increased since 2006, and scientists want to understand why. NASA explained that various teams of scientists have had different explanations for the puzzling increase in methane! Badman Nishioka/This report,
Some teams have published evidence showing that emissions from biogenic [living] sources is driving the increase. Wetlands, ruminants, and rice paddies — all home to methane-producing microbes — are some of the major sources of biogenic methane.
Other teams have argued that a simultaneous increase in atmospheric ethane, a key component of natural gas, implies that fossil fuels are the culprit. Extracting and transporting fossil fuels add both ethane and methane to the atmosphere via leaks in wells, pipes, and other infrastructure.
Worden’s new analysis suggests that both fossil fuels and biogenic sources (wetlands and agriculture) are the primary drivers of the increase.

    Indeed! The permafrosts in Siberia, Alaska, Northern Canada, Greenland have keeping about 1140-1476 Giga tons of carbon emissions. This permafrosts melted since 15 years before slowly, but recently rapidly melted,,,, on last October, the temperature in Eastern north Siberia was 15-18C by Siberian Times, others.

  2. The areas of permafrost in Siberia. So the Northen areas in forests including wetlands, moss, freezing soils melted,,, some scientist say, "if those trends of temperature continue, the 40-50% permafrosts gone or not"! Badman Nishioka/rainforest action group/ One week before we invited the member of Wetlands International Indonesia to Osaka, and Tokyo.
