I’ve always wondered: do nuclear tests affect tectonic plates and cause earthquakes or volcanic eruptions?

Human-induced earthquakes have been reported from every continent except Antarctica. We asked a geologist to investigate whether North Korea's nuclear tests could trigger geological changes.

After 30 years of the Montreal Protocol, the ozone layer is gradually healing

The treaty to limit the destruction of the ozone layer is hailed as the most successful environmental agreement of all time. Three decades on, the ozone layer is slowly but surely returning to health.

Satellites reveal melting of rocks under volcanic zone, deep in Earth’s mantle

New research shows that satellite measurements of tiny movements of the Earth's surface can tell scientists what is happening in the deeper layers of our planet.

Volcanoes under the ice: melting Antarctic ice could fight climate change

Melting ice from Antartica could feed vast plankton blooms, trapping carbon in the ocean. To understand this complex mechanism, researchers looked at volcanoes deep under glaciers.
