Climate change uncovers archaeological finds. Scientists are looking for ways to preserve them

As climate change amplifies severe weather, it’s also delivering something unexpected: archaeological finds. Droughts, for example, recently uncovered 113-million-year-old dinosaur tracks in Texas and World War II-era boats in Nevada.

The findings are exciting but bring challenges, including how to safely and quickly preserve and study them. And in some cases, whether it's ethical to dig or move sensitive artifacts.

Last fall, we spoke to Sarah Parcak, an archaeologist and Egyptologist at the University of Alabama Birmingham, where she also directs the Laboratory of Global Exploration. Her team uses drones and satellites to look underground, earning her the nickname, 'the space archaeologist.' Parcak joins host Scott Tong to discuss her work.
