Great Salt Lake identified as source of greenhouse gas emissions
Like some dystopian astronaut, Melissa Cobo would hike the searing flats of the dried-out Great Salt Lake every couple of weeks, hauling a heavy backpack attached by a hose to what looked like the lid of a cake dome. … Through these grueling treks, Cobo, then a Utah State University graduate student, and her adviser, Soren Brothers, discovered more disturbing evidence that dried-out lakes are a significant source of carbon dioxide emissions — one that has not been included in the official accounting of how much carbon the world is releasing into the warming atmosphere. In a new study in the journal One Earth, the researchers calculated that 4.1 million tons of carbon dioxide and other greenhouse gases were released from the drying bed of the Great Salt Lake in 2020, the year Cobo and others collected the samples. This would amount to about a 7 percent increase in Utah’s human-caused emissions, the authors found.
