One US Oil Field a Key Culprit In Global Ethane Gas Increase

An anonymous reader writes: According to scientists, a single U.S. shale oil field is responsible for much of the past decade's increase in global atmospheric levels of ethane, a gas that can damage air quality and impact climate. The Bakken Formation, an oil and gas field in North Dakota and Montana is spewing nearly 2% of the globe's ethane. That translates to about 250,000 tons each year. "Two percent might not sound like a lot, but the emissions we observed in this single region are 10 to 100 times larger than reported in inventories. They directly impact air quality across North America. And they're sufficient to explain much of the global shift in ethane concentrations," said Eric Kort, U-M assistant professor of climate and space sciences and engineering.The Washington Post has more details (paywalled; alternatively you can read this Gizmodo report)

    Before you complain about the chemical being ethane, note that ethane + air + sunlight = ozone.

      Ozone in the stratosphere = good
      It blocks UV radiation from the Sun and without it there wouldn't be life as we know it on the dry land of Earth.

    The source is the article linked above. As in, the article you should have read before commenting.

    Looks like the Church of Climatology is jealous of the levels of esteem & high regard held for the Church of Scientology and the Westboro Baptist Church, and are exerting maximum effort towards correcting that discrepancy.

    Can't fault the CoC for lack of effort in that regard.

    The Church of Climatology: The US Progressive/Liberal version of the bastard-child of the Westboro Baptist Church and the Church of Scientology if they bred. Even the tactics they use against their critics are nearly indistinguishable.

  10. What about the Methane???? by TheSync · · Score: 2

    If there is some kind of huge ethane leak from the Bakken, you can be sure there is a huge methane leak as well.

    Ethane makes up 10% mole percent of LNG at most, the other 90% is mostly methane.

    Methane is a very significant global warming gas, more so than CO2, although its half-life in the atmosphere is much shorter than CO2.

    1. Re:What about the Methane???? by ari_j · · Score: 2

      The wells in that region produce mostly crude oil and natural gas. Crude oil is easy to store in tanks, put into tanker trucks, and otherwise get off the well site to the market in a variety of ways that you can use from day 1 of drilling the well. Natural gas must either go into a pipeline, be vented into the atmosphere, or be flared (burned) into the atmosphere. Pipelines can take years to catch up to drilling (not really due to regulation as others have pointed out, but rather due to rapid drilling for profitable oil outpacing thousands of miles of pipeline construction to sell much less profitable natural gas, along with lack of enforcement of regulations intended to restrict flaring to a certain time period after drilling a new well). So a lot of gas has to be vented or flared. Venting is considered worse than flaring for the atmosphere (because methane is a worse global warming gas than CO2 as you pointed out), so it all gets flared. Perhaps flaring burns the methane but not the ethane, or at least not all of it, which is why ethane is the problem we are focusing on here?

    Yes, you did miss it. Maybe because it wasn't actual climate scientists, but the church's parishioners that claim to speak for them.
