If we want to quickly combat climate change, we need to deal with “the other” greenhouse gas: methane. Methane leaks are heating up the planet and harming people who live where gas drilling takes place. 

Reporter Elizabeth Shogren introduces us to a NASA scientist who’s devoting his career to hunting down big methane leaks. Riley Duren and his team have figured out how to spot methane pollution from airplane flyovers, and in an experiment, his data was used to make polluters plug their leaks. Scientists have answers to the methane problem. The question is whether governments will step up to fund a comprehensive methane monitoring system. 

Next, Shogren zooms in on Arlington, Texas, a community that bet heavily on drilling for methane, the main ingredient in natural gas. There are wells all over Arlington, next to homes and shopping centers, even day cares and schools. Arlington’s children have unwittingly been part of an experiment to see what happens when gas wells and people mix. We follow one preschool that is trying to stand up to a large drilling company. Last year, the City Council voted to block new natural gas wells near the school’s playground, then reversed its vote. After protests, gas drilling has been blocked once again – if only for a year. 

We end the show with a story from Reveal’s Brett Simpson about a serious source of methane that is often overlooked. Cows and other livestock produce 14% of the world’s methane emissions, in many places belching more of the gas than oil and gas wells. We meet a scientist who’s figured out how to reduce methane emissions from cows by 80%.
