Can global warming trigger volcanoes?

Sarah Lucas The suggestion that volcanic eruptions can influence the climate makes intuitive sense. Volcanoes emit carbon dioxide, an important greenhouse gas, and provide a link between deep carbon reservoirs in the Earth’s interior and the Earth’s surface. Mass volcanic activity can release large quantities of carbon dioxide, warming the climate over millions of years.... Continue Reading →

Some of these, such as lava flows, tend to be localised, while others, such as plumes of ash and gas can travel across the globe.

Kaja Fenn You might have heard about radiocarbon dating, but do you know about OSL dating? OSL stands for Optically Stimulated Luminescence, and is another method of determining when processes and events occurred in the past. It has some distinct advantages over radiocarbon dating, which I will discuss. Before looking at OSL in more detail... Continue Reading →
