As the Great Salt Lake Dries Up, It's Also Emitting Millions of Tons of CO2

Scientists say the drying Great Salt Lake in Utah is now becoming a significant contributor to global greenhouse gas emissions that are causing the climate to warm, according to a new study. From a report: Due largely to water diversions by farmers and Utah's booming population growth, the Great Salt Lake has shrunk by almost half in recent years. Scientists spent seven months in 2020 sampling emissions coming off the dried saline lake bed. Canada's Royal Ontario Museum published the study on Thursday in the journal One Earth. [...] The researchers found that the drying lake bed emitted 4.1 million tons of carbon dioxide and other greenhouse gases into the atmosphere, which would translate to a 7% increase in Utah's human-caused emissions. According to scientists, 4 million tons of CO2 is roughly equivalent to the total annual emissions of 140 commercial planes. The Great Salt Lake is the largest saline lake left in the Western Hemisphere. The study occurred during one of the most notorious dry stretches of the West's mega drought, which had lasted two decades at the time of the study.
