Under the Crust

We see the gloopy lava or the clouds of hot rock and ash emerging from volcanoes, but what determines what erupts? How big will the eruption be? Who will be affected? Here we take a peek at the “engine room” beneath some of the world’s volcanoes to discover the triggers of eruptions. Meanwhile, on the surface we can get clues from rock fragments ejected and deposited around the vent to help understand the frequency and violence of past eruptions.

Through burning of fossil fuels we inject tons of carbon dioxide into the atmosphere, disturbing the Earth’s energy balance by increasing the greenhouse gas effect. Global warming is real as we observe it in the fast melting of polar ice caps, rising sea level and devastating droughts. However, this is not a dead end. Here, we explore how advanced technologies can mitigate global warming by reducing the impact of fossil fuel burning.
