Utah’s Great Salt Lake holds a unique ecological niche as the western hemisphere’s largest saltwater lake. The body of water is three to five times saltier than the ocean, with salinity ranging between 12 and 28 percent. According to the Great Salt Lake Institute, millions of birds from more than 250 species rely on the lake yearly, alongside a diverse variety of plants and animals. 

Like many bodies of water in the U.S., climate change is affecting the status quo in the Great Salt Lake. The water is drying up at an alarming rate, reaching its lowest level in recorded history this month. Now, researchers warn that toxic dust could increase as water levels continue to drop.

Joining Ira to discuss the Great Salt Lake’s ecosystem and future is Bonnie Baxter, director of the Great Salt Lake Institute and biology professor at Westminster College in Salt Lake City, Utah.
