Utah scientists knew that the Great Salt Lake has been drying up, and they have been warning the politicians for years about it. But nothing's been done, the alfalfa farmers suck up water like nobody's business and the politicians don't want to do any major actions that would actually solve the issue. I don't have the exact figure off the top of my head, but the water level has dropped over half the original height now. A bit frightening to see, I'm convinced the lake will be gone entirely within my lifetime.
The dust causing the snow to melt is the least of our worries, the Great Salt Lake is absolutely nasty. Who knows what kind of dangerous pollutants will now be kicked up by the air?
