Huge Methane Plume over China
A massive plume of methane, the potent greenhouse gas that’s a key contributor to global warming, has been identified in China’s biggest coal production region.
The release in northeast Shanxi province is one of the largest that geoanalytics company Kayrros SAS has so far attributed to the global coal sector and likely emanated from multiple mining operations.
Details captured in European Space Agency satellite data show the plume about 90 kilometers (56 miles) east of Shanxi’s capital Taiyuan, in Yangquan City. The area has 34 coals mines, according to the Shanxi Energy Bureau.
The emissions rate needed to produce the plume observed in the June 18 satellite image would be several hundred metric tons an hour. For comparison, a 200-ton per hour release would have roughly an equivalent climate warming in the first two decades as 800,000 cars driving at 60 miles an hour.
