Global change: Hydrocarbon-driven warming
Gerald R. Dickens1
Abstract
A dramatic historical episode of global warming seems to have been driven by the release of huge amounts of hydrocarbons. New evidence for what might have happened comes from the sea floor off Norway.
The outstanding examples of intense global warming and massive greenhouse-gas emissions occurred during a brief episode, known as the 'initial Eocene thermal maximum' (IETM), about 55 million years ago. Superimposed on already warm climates, Earth's surface temperatures soared by 5–10 °C within a geological instant1, 2.
