"NASA scientists track climate-changing Methane Leaks from the air" PBS NewsHour 7/11/2018

Excerpt

SUMMARY:  Science correspondent Miles O’Brien joins us from the atmosphere above Southern California, where NASA engineers leverage state-of-the-art technology to measure methane.  Released through oil and gas production, livestock emissions, and organic waste, methane is about 85 times more potent at trapping heat than carbon dioxide.  California wants to identify specific methane leaks so it can plug them.
