Underground Time Machines: ow Caves Record Earth's Climate History
Deep in remote caves across Southeast Asia, stalactites and stalagmites are quietly recording thousands of years of climate history. These records could help us prepare for future climate change, especially in regions where billions depend on seasonal rainfall.
Join Dr. Kathleen Johnson as she shares how these cave formations preserve detailed signals of past monsoon variability. She'll also share tales of the adventurous fieldwork—involving close encounters with bats, giant spiders, snakes, and leeches—and the painstaking lab work required to unravel the geochemical clues preserved in these ancient stalagmites. Discover how these underground time machines help us decode Earth's climate past to better understand our future.
