Huge methane cloud spotted above Mpumalanga’s coal fields
Two more plumes of the greenhouse gas detected nearby, but two mining giants claim to not know its source
A cloud of methane was detected by satellite near coal mines in SA, drawing attention to a lesser-known environmental risk that comes from using the dirtiest fossil fuel.
The potent greenhouse gas — methane traps roughly 84 times more heat than carbon dioxide in its first two decades in the atmosphere — was emitted at an estimated rate of 65 tons an hour on May 10, according to Kayrros. The Paris-based analytics company found the leak by parsing European Space Agency satellite observations. It was the worst plume of methane Kayrros detected in the data over Africa this year...
