Multimedia | Climate Change and Mono Lake
Dec, 06 2013
Geologist Guleed Ali of the Lamont-Doherty Earth Observatory is exploring the history of climate at Mono Lake in eastern California, looking back tens of thousands of years into the last ice age. The lake's watershed serves as a water supply for far-away Los Angeles; in the midst of a broader drought in the Southwest, it's vital to understand how future climate change will affect the lake. Ali studies sediments in ancient river banks and algal deposits on limestone towers formed in the highly salty and alkaline waters of the lake. By dating the rise and fall of the lake over time, he and colleagues at Lamont hope to correlate those fluctuations to changes in the region's climate.
