At the 2025 Goldschmidt Conference, researchers shared that melting glaciers and ice caps may lead to more volcanic eruptions. They looked at what happened between 26,000 and 10,000 years ago.
The biggest risks are in West Antarctica, but North America, New Zealand, Russia, Iceland, and Chile could also be affected. When glaciers melt, they take away pressure. That lets magma rise and rocks melt faster, possibly causing explosions.
Climate change is also making more rain and snow, which can mix with hot magma. Scientists believe this could also help trigger eruptions. When volcanoes erupt, they can cool Earth by releasing ash, but they might also heat it over time by releasing greenhouse gases like carbon dioxide.
Recent studies in Smithsonian Magazine and Live Science point to rising volcanic activity in North America, New Zealand, and Russia, though exact numbers for the last decade are missing. According to GKToday, volcanic events in Iceland surged 30 to 50 times after glaciers melted in the past, showing deglaciation can strongly increase eruptions.
More research about how melting glaciers affect volcanoes is needed. Understanding these connections might help keep people safer in the future as the planet continues to change.
