Ghostly River Reveals Pyrénées' Climate Secret
19 May
Summary
- Underground aquifers are crucial in the eastern Pyrénées, an area hit hard by climate change.
- Hydro-speleologists explore these subterranean water sources to understand their function.
- The Tirounère River, over 60 meters below, plays a role in this vital ecosystem.

Areas of the eastern Pyrénées mountains, significantly impacted by climate change, are finding immense value in their underground aquifers. These subterranean water reserves are proving crucial for the region's water supply and ecosystem health.
To gain a deeper understanding of how these vital water systems function, hydro-speleologists are undertaking expeditions deep underground. Their work involves descending into caves and subterranean waterways, such as the eerily named Tirounère River, which flows more than 60 meters below the surface. These explorations aim to map and study the complex dynamics of these hidden water sources.
