Ultimate Cause

‘How to kill nearly everything’ considers the proposed causes of mass extinctions, often called the kill mechanisms. An almost bewildering array of ideas have been put forward as likely bringers of death, but most of the debates have concentrated on just a few culprits, notably volcanism and meteorite impact, because their timing is closely coincidental with the extinctions. However, it is important to note that while they may be the ultimate cause of a crisis, it is their consequences that likely lead to proximate (or direct) causes of extinction. The main causes discussed are large igneous provinces, hyperthermals, ocean anoxia, ocean acidification, ozone depletion, ice ages, sea-level change, and meteorite and comet impacts.

Carbon is one of the most important elements on Earth. It is the basis of life, it is stored and mobilized throughout the Earth from core to crust and it is the basis of the energy sources that are vital to human civilization. This issue will focus on the origins of carbon on Earth, the roles played by large-scale catastrophic carbon perturbations in mass extinctions, the movement and distribution of carbon in large igneous provinces, and the role carbon plays in icehouse–greenhouse climate transitions in deep time. Present-day carbon fluxes on Earth are changing rapidly, and it is of utmost importance that scientists understand Earth's carbon cycle to secure a sustainable future.
