Great Salt Lake is releasing more than dust
A new harm of allowing Great Salt Lake to shrink has come to light, thanks to research from Utah State University. By now, we’ve sounded the alarms about the lakebed turning to dust and heavy metals blowing through our air from that dust, losing crucial habitat for 10 million migratory birds, losing billions in industry provided by the lake, as well as thousands of jobs, and losing an iconic natural feature of our state. This new research shows that the shrinking of the lake is releasing a significant amount of greenhouse gas emissions.
A 2023 report out of BYU expressed the importance of taking urgent legislative and policy action, “We are underestimating the consequences of losing the lake. Despite encouraging growth in legislative action and public awareness, most Utahns do not realize the urgency of this crisis. Examples from around the world show that saline lake loss triggers a long-term cycle of environmental, health, and economic suffering30–35. Without a coordinated rescue, we can expect widespread air and water pollution, numerous Endangered Species Act listings, and declines in agriculture, industry, and overall quality of life1–4,36.”
The Salt Lake Tribune reported, “The U.S. Energy Information has reported that Utah generally emits 60 million tons of carbon dioxide per year from burning fossil fuels.
Including the lake’s emissions — which are tied to humans diverting water for farming, mining and to serve a growing population — resulted in a 7% increase to Utah’s total.”
The exposed lakebed allows microorganisms to break down organic matter, releasing greenhouse gasses. Areas recently exposed emit more greenhouse gas than those uncovered for longer periods.
Increased emissions from the lake add to the pollution burden, potentially exacerbating respiratory and other health issues among residents.
Understanding the full impact of Great Salt Lake’s decline is crucial for pushing state officials to make meaningful changes to preserve the lake. This study underscores the importance of comprehensive water management policies and the need for immediate actions to address the environmental and health challenges posed by the shrinking lake.
UPHE recognizes the dire consequences of continuing business as usual, and joined a lawsuit with other groups to hold the state accountable. The primary loss of water is coming from agricultural use. This must be decreased if the lake has any chance at reviving.
