for emissions from a mud volcano in western Turkmenistan in January 2019, a satellite called came across a large plume of methane drifting across the landscape. The discharge appeared to originate from a gas pipeline at the nearby Korpezhe oil and gasfield. Two more large plumes were also spotted in the area, including one from a compressor station. The company operating the satellite, at, based in Montreal, passed details via diplomats to officials in Turkmenistan, and after a few months the leaks stopped. This largely unknown incident illustrates two things: that satellites can play an important role in spotting leaks of greenhouse gases and, rather worryingly, that the extent of such leaks is often greatly underestimated.The reason for concern is that although methane, the main constituent of natural gas, does not linger in the atmosphere for anywhere near as long as carbon dioxide does, it is a far more potent heat-trapping agent. About a quarter of man-made global warming is thought to be caused by methane. And between a fifth and a third of the methane involved is contributed by the oil and gas industry.
