Check your bucket: climate change could widen Lake Mead
KPCC, Southern California Public Radio reported on a new study by IoE Director Glen MacDonald.
Seen Lake Mead lately? The bathtub ring - what locals call the white walls of the canyon covered with mineral deposits - keeps growing taller. If UCLA researchers are right, a confluence of natural circumstances will continue to make the bathtub ring grow - and that spells trouble for states that depend on Colorado River water.
UCLA's Glen MacDonald and a former graduate student of his, Abbie Tingstad, went to the Uinta Mountains region in northeastern Utah to examine tree rings in that region. Studying the rings of Pinyon Pines, they reconstructed about a millenium of snowpack and river flow information for the region - whose climate is representative of the upper Colorado River.
