Impact of Carbon Emission on Earth's Future: Lessons from the Past

This article discusses the impact of carbon emission on Earth's future by studying the past events of Permian extinction episode. It explains how rising temperatures and depletion of oxygen in oceans can lead to mass extinction. It also describes how the current emission rates might see the level of greenhouse gases reach a potential that is similar to those that triggered the great extinction that took place towards the end of the Permian geologic era.
