Elements: Catastrophic Perturbations to Earth's Deep Carbon Cycle

October 14, 2019

This issue explores the origins of carbon on Earth; the long-term carbon cycle; catastrophic and large-scale perturbations to Earth's carbon cycle such as large igneous provinces and bolide impacts; carbon's role in mass extinctions; and icehouse–greenhouse climate transitions in deep time. Deciphering the complex, and often faint, signals of distant carbon catastrophes requires a multidisciplinary effort and the most innovative analytical technology. This thematic collection comes at an important time in which carbon fluxes on Earth are changing rapidly.
