Melting glaciers and ice caps could unleash wave of volcanic eruptions, study says

Research in Chile suggests climate crisis makes eruptions more likely and explosive, and warns of Antarctica risk

The melting of glaciers and ice caps by the climate crisis could unleash a barrage of explosive volcanic eruptions, a study suggests.

The loss of ice releases the pressure on underground magma chambers and makes eruptions more likely. This process has been seen in Iceland, an unusual island that sits on a mid-ocean tectonic plate boundary. But the research in Chile is one of the first studies to show a surge in volcanism on a continent in the past, after the last ice age ended.

U-Boot v2025.07 released

The U-Boot universal bootloader project has announced the release of version 2025.07. It has multiple new features including "uthreads" (inspired by the "bthreads" coroutines in the barebox bootloader), exFAT support, new architecture and SoC support and improvements to existing platforms, cleanups, better testing, and more. Project leader Tom Rini took the opportunity to mention his efforts toward getting some help with the project and more formal governance:
As this is a full release, and not just a release candidate I'm hoping for a few more people to read this and then read what I'm linking to as well. For the overall health of the project, and the community, I'm hoping to find a few people within the community that can help with overall organization and management. I would like to long term be able to move us to being under the Software Freedom Conservancy umbrella and that in turn means having a organizational structure that's not just a single person.

He also noted that there is a community meeting on July 8th, 2025 at 9am (GMT -06:00) on Google Meet.
