The Scientist Hunting for Cave Crystals to Understand Climate Change

Gina Moseley, a paleoclimatologist at Austria’s University of Innsbruck, has been caving since she was 12.

The world’s cave climate record goes back about 600,000 years.

But when she visited Shatter Cave in the southwest U.K., Moseley was on the hunt for a relatively young relic of climate change: tiny crystals from the last Ice Age that formed when permafrost melted.
