US Edition"More Explosive And Frequent": Melting Glaciers Might Trigger Volcanic Eruptions Globally, Study Warns
CHILE, JUL 10 – Research shows glacier retreat reduces pressure on magma chambers, increasing eruption frequency and explosivity; 245 volcanoes near ice surfaces are at risk globally, scientists warn.
- On July 8 at the Goldschmidt Conference in Prague, University of Wisconsin-Madison researcher Pablo Moreno-Yaeger presented findings that melting glaciers could increase volcanic eruptions worldwide.
- Melting glaciers reduce pressure on Earth's crust, enabling gases and magma to expand and potentially trigger eruptions.
- Crystal analysis and argon dating of past eruptions in Iceland confirm a 30–50 fold increase in volcanic activity after the last ice age, evidencing glacial influence.
- Scientists warn that hundreds of dormant Antarctic subglacial volcanoes could awaken as glaciers melt, posing an immediate global volcanic risk.
- Long-Term projections indicate that sulfate aerosols from eruptions cause short-term cooling, but greenhouse gases accelerate warming, creating a feedback loop that may hasten glacier melt.

Horrifying Research Finds Melting Glaciers Could Activate Deadly Volcanoes
Scientists are warning that glaciers melting due to global warming could trigger explosive — and potentially deadly — volcanic eruptions around the world. As detailed in a new study presented at the Goldschmidt international geochemistry conference this week and due to be peer-reviewed later this year, researchers from the University of Wisconsin-Madison analyzed six volcanoes in southern Chile to study how retreating ice sheets may have influen…
Melting Glaciers Could Lead to More Frequent and Explosive Volcanic Eruptions: Study
Ice loss from melting glaciers around the world due to global heating could cause pressure to be released from volcanic magma chambers located deep underground. The process — already seen in Iceland — makes volcanic eruptions more frequent and powerful, according to new research conducted in the Chilean Andes. “As glaciers retreat due to climate change, our findings suggest these volcanoes go on to erupt more frequently and more explosively,” sa…
An Earth in the middle of the void could explain a cosmological mystery.

Global warming causes unexpected and increasingly worrying effects.The melting of glaciers could be creating the conditions for more explosive and frequent volcanic eruptions to occur in the future, as demonstrated by the results of research carried out in six volcanoes in the Chilean Andes.A recent study argues that hundreds of subglacial volcanoes, i.e. located under the ice, are now inactive around the world, but especially in Antarctica, cou…
Are thawing glaciers about to wake up dormant volcanoes around the globe?
For centuries, glaciers have sat like frosty crowns atop slumbering volcanoes, keeping Earth’s fury tucked safely beneath layers of ice. But now, as climate change accelerates and glaciers retreat, the lid may be lifting, and the heat rising.Continue ReadingCategory: Environment, ScienceTags: Antarctic, volcano, Climate Crisis, glacier, Ice, Global Warming
