A study of methane

In fact, research in the US has found that shale gas wells are often far less leaky than their conventional brethren. Role of atmospheric oxidation in recent methane growth. If methane sinks weaken, atmospheric concentrations of methane may continue to rise even if emissions are constant.

These "top-down" readings add to traditional "bottom-up" readings, or measurements taken right at the potential emission source, often at ground level.

The new studies will help refine the global estimates that do exist while improving national estimates. Methane from biological sources such as cows and wetlands have a low carbon content -- compared to methane from most fossil fuels.

A study of methane

This existing body of research presents mixed results, with some researchers arguing that the recent growth in concentrations has been driven primarily by biogenic sources e. Role of atmospheric oxidation in recent methane growth. So the researchers deployed various scientific techniques. CSU researchers are quantifying emissions from gathering and processing plants and transmission and storage facilities. Hausmann, P. A variety of detailed analyses from dozens of authors have come to different conclusions about the relative contributions of fossil fuel development, biogenic sources, natural sinks, and more. World Energy Outlook Previous studies erroneously concluded that biological sources are the cause of the rising methane, Howarth said. At each point in the process of production, methane can be released into the atmosphere as a result of leakage. Note: Content may be edited for style and length. These "top-down" readings add to traditional "bottom-up" readings, or measurements taken right at the potential emission source, often at ground level.

International Energy Agency. However, relatively little is known about emissions from one of its largest man-made sources, the oil and gas industry. It's the low-hanging fruit to slow global warming. Neither the citations provided by Howarth nor the report provide data on the share or levels of coal mined from the surface or underground mines.

CH4 emissions from oil and gas production: Have recent large increases been detected?

So inwe launched an extensive series of 16 independent, rigorously executed projects. Phase 2, which started inconsists of field studies using multiple measurement methods. Accessed: 19th August International Energy Agency.
