Northern Arizona sand dunes - USGS podcast

The USGS podcast posted today covers the impacts of climate change on "the mobility of sand dunes in the southwest, posing threats to roadways, infrastructure, human health, cultural practices of the Navajo Nation, and much more. Vegetation on dunes serves as stabilizers, but as the climate warms and precipitation decreases, there is less vegetation growth."

USGS scientist Margaret Hiza and intern Leanna Begay discuss their research to understand the dunes' plant diversity and what changes are occurring.

Thanks to The Geology News Blog for spotting this.
