Pamir glaciers suffer abrupt melt after decades of relative stability

A glacier region long seen as an exception to global ice loss recorded an extraordinary melt season in 2025, raising concern that extreme heat is overwhelming one of Asia’s last relatively stable ice reserves.

Key Takeaways

Researchers recorded record ice loss at the Kangxiwa glacier in 2025.
The glacier lost the equivalent of 1.5 metres of water across its surface.

Alaska’s 2025 Megatsunami Is Emerging as a Climate and Hazard Warning

Scientists reconstructed the 2025 landslide-generated tsunami in Alaska’s Tracy Arm and found a maximum runup of 481 meters, making it the second highest tsunami known to humans.

Key Takeaways

A landslide triggered by retreat of Alaska’s South Sawyer Glacier generated a 2025 tsunami with a 481-meter maximum runup.
Researchers used satellite images, aerial images, and ground-based data to reconstruct the event in a Science paper.

NASA Imagery Shows How a Glacier-Driven Landslide Rewrote an Alaskan Fjord in Minutes

New before-and-after imagery from NASA and USGS captures the aftermath of a 2025 landslide-triggered tsunami in Alaska’s Tracy Arm, revealing how quickly warming landscapes can reshape hazardous terrain.

Key Takeaways

NASA released before-and-after Landsat imagery of the Tracy Arm disaster zone.
A landslide of at least 64 million cubic meters triggered a tsunami on August 10, 2025.

Iron Fertilization Theory Challenged: Melting Glaciers May Not Offset Climate Change

A long-standing theory that melting Antarctic glaciers could help slow climate change by releasing iron that feeds carbon-absorbing algae is being undermined by new research. Scientists studying the Southern Ocean have found the theory 'doesn't hold water,' potentially removing a silver lining from climate projections.
