The next major volcanic eruption could kick-start chemical reactions that would seriously damage the planet's already besieged ozone layer. The extent of damage to the ozone layer that results from a ...

A simulation of the evolution of the Earth's interior over time, showing the thermal (bottom), chemical (middle) and thermochemical evolution under the simulated conditions. The bottom of each field ...
