New tipping point unlocked: melting ice caps could unleash wave of volcanic eruptions (www.theguardian.com)

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.

Global heating caused by the burning of fossil fuels is now melting ice caps and glaciers across the world. The biggest risk of a resurgence of volcanic eruptions is in west Antarctica, the researchers said, where at least 100 volcanoes lie under the thick ice. This ice is very likely to be lost in the coming decades and centuries as the world warms.

Volcanic eruptions can cool the planet temporarily by shooting sunlight-reflecting particles into the atmosphere. However, sustained eruptions would pump significant greenhouse gases into the atmosphere, including carbon dioxide and methane. This would further heat the planet and potentially create a vicious circle, in which rising temperatures melt ice that leads to further eruptions and more global heating.
