University of Texas researchers identified a pattern of measurement errors from the Bacharach Hi-Flow Sampler, a device widely deployed at natural gas facilities, which the Environmental Protection Agency uses to collect nationwide data on methane emissions. The device switches between two sensors that measure low and high intensity leakages. Researchers found the device frequently malfunctioned in the handoff, resulting in “systematically underestimated emissions.” The study was published Tuesday in the journal [Energy Science & Engineering](http://onlinelibrary.wiley.com/doi/10.1002/ese3.81/abstract). ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3983516/methane-greenhouse-gas-emissions/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3983516/methane-greenhouse-gas-emissions/"},"headline":"New Methane Measurements Suggest Pollution is Worse Than Researchers Thought","datePublished":"2015-08-04T13:03:07.000Z","dateModified":"2023-12-14T22:02:05.000Z","description":"Methane can have a major effect on global warming","url":"https://time.com/3983516/methane-greenhouse-gas-emissions/","keywords":["climate change","Tech"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt08fd97666d447502/69885ddaf887dcba58e91b50/natural-gas-production-facility.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Dan Kedmey","jobTitle":null,"url":"https://time.com/author/dan-kedmey/"}],"articleSection":"Science","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt08fd97666d447502/69885ddaf887dcba58e91b50/natural-gas-production-facility.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Caucasian technicians tightening bolts on pipe","caption":"Caucasian technicians tightening bolts on pipe","creditText":"Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/science/","name":"Science"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/climate-change/","name":"climate change"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3983516/methane-greenhouse-gas-emissions/","name":"New Methane Measurements Suggest Pollution is Worse Than Researchers Thought"}}]}] ```
