'Extremely exciting': the ice cores that could help save glaciers
Scientists retrieved 105-meter ice cores from the Pamir Mountains to analyze climate history and investigate why regional glaciers resist melting, aiding global glacier preservation efforts.
- At 5,810 metres on the Pamir Mountains, Iizuka's team drilled ice cores, with one stored in Antarctica and the other shipped to Hokkaido University in Sapporo, AFP reports.
- Seeking to explain the Pamir-Karakoram anomaly, researchers test hypotheses like cold local climate, regional agricultural water use in Pakistan, and historical mining in the region, noting much glacier melt around 6,000 years ago.
- At Hokkaido University Institute of Low Temperature Science, Sora Yaginuma described the core as `an ice core is an extremely valuable sample and unique`, as team members cut samples in minus 20C freezers and logged grain alignment.
- The team hopes to publish its first findings next year and expects 'lots of trial-and-error' to reconstruct past climate conditions, while Yoshinori Iizuka said this could help protect global glaciers at risk.
- Scientists will use volcanic sulfate ions as time markers and water isotopes as temperature proxies, with chemical and physical analyses revealing decades of weather and precipitation history.

'Extremely exciting': the ice cores that could help save glaciers
Dressed in an orange puffer jacket, Japanese scientist Yoshinori Iizuka stepped into a storage freezer to retrieve an ice core he hopes will help experts protect the world's disappearing glaciers.

In the heart of the Pamir mountains, scientists pierce the secrets of a climate anomaly. Their discoveries could offer unprecedented paths to preserve the world's glacial masses. In the laboratories of the University of Hokkaido, Japan, researchers search ice samples brought back from the heights of Tajikistan. These carrots, drilled at more than 5,800 [...] Read more Ice archives, the ultimate bulwark against the disappearance of glaciers appea…
