Coal Mining Emits More Super-Polluting Methane Than Venting and Flaring From Gas and Oil Wells, a New Study Finds

Methane emissions from coal mines worldwide exceed those from the global oil or gas sectors and are significantly higher than prior estimates by the Environmental Protection Agency and the International Energy Agency, a new Global Energy Monitor report concludes.

“The numbers just aren’t adding up,” Ryan Driskell Tate, the report’s author, said of coal mine methane emission estimates when compared to those in prior reports. “It’s an area that has dodged a lot of scrutiny.”

Coal mining emits 52 million metric tons of methane per year, more than is emitted from either the oil sector, which emits 39 million tons, or the gas industry, which emits 45 million tons, according to the report, published Tuesday.

Thawing Permafrost Could Leach Microbes, Chemicals Into Environment

…
Trapped within Earth’s permafrost – ground that remains frozen for a minimum of two years – are untold quantities of greenhouse gases, microbes, and chemicals, including the now-banned pesticide DDT. As the planet warms, permafrost is thawing at an increasing rate, and scientists face a host of uncertainties when trying to determine the potential effects of the thaw.

A paper published earlier this year in the journal Nature Reviews Earth & Environment looked at the current state of permafrost research. Along with highlighting conclusions about permafrost thaw, the paper focuses on how researchers are seeking to address the questions surrounding it.

Infrastructure is already affected: Thawing permafrost has led to giant sinkholes, slumping telephone poles, damaged roads and runways, and toppled trees. More difficult to see is what has been trapped in permafrost’s mix of soil, ice, and dead organic matter. Research has looked at how chemicals like DDT and microbes – some of which have been frozen for thousands, if not millions, of years – could be released from thawing permafrost.

To Counter Global Warming, Focus Far More on Methane, a New Study Recommends

The Environmental Protection Agency is drastically undervaluing the potency of methane as a greenhouse gas when the agency compares methane’s climate impact to that of carbon dioxide, a new study concludes.

The EPA’s climate accounting for methane is “arbitrary and unjustified” and three times too low to meet the goals set in the Paris climate agreement, the research report, published Wednesday in the journal Environmental Research Letters, found.

The report proposes a new method of accounting that places greater emphasis on the potential for cuts in methane and other short-lived greenhouse gasses to help limit warming to 1.5 degrees Celsius above pre-industrial levels.

“If you want to keep the world from passing the 1.5 degrees C threshold, you’ll want to pay more attention to methane than we have so far,” said Rob Jackson, an earth system science professor at Stanford University and a co-author of the study.

Scientists raise alarm over ‘dangerously fast’ growth in atmospheric methane

Methane concentrations in the atmosphere raced past 1,900 parts per billion last year, nearly triple pre-industrial levels, according to data released in January by the US National Oceanic and Atmospheric Administration (NOAA). Scientists says the grim milestone underscores the importance of a pledge made at last year’s COP26 climate summit to curb emissions of methane, a greenhouse gas at least 28 times as potent as carbon dioxide.

The growth of methane emissions slowed around the turn of the millennium, but began a rapid and mysterious uptick around 2007. The spike has caused many researchers to worry that global warming is creating a feedback mechanism that will cause ever more methane to be released, making it even harder to rein in rising temperatures.

It’s time to look harder at landfills if we’re serious about addressing climate change

– The EPA has stated it believes estimates of methane emissions from landfills may be twice as high as models indicate. While the landfill industry might disagree, numerous field studies have found that methane emissions are actually much higher than estimated. A 2016 study by Germany’s Institute for Energy and Environmental Research identified that landfill operators’ claims of methane recovery left out substantial amounts of emissions.

-Waste management companies are no longer just local contractors and the largest landfill operators are now national publicly traded companies. Substantial sums have been spent at the federal and state level by the waste management industry to influence the development and implementation of regulations. It is clear that waste companies have a vested interest in maintaining the status quo, and are willing to spend to do so.

-As more and more people come to realize the urgency of the climate crisis and the need for real and significant action, the U.S. must follow suit. As European Union Commission President Ursula von der Leyen said before the opening of the COP26 conference in Glasgow, now comes the “moment of truth” that will affect the “survival of mankind.”
