Abstract

The rapidity and amount of carbon being released through human agency have been thought to be unprecedented. Not so, it emerges. From the evidence of anomalies in the ratios of carbon isotopes in an ocean core, it seems that, around 55 million years ago, there was an equivalently swift and massive blast of carbon into the ocean and atmosphere. The source was probably methane hydrates that are usually locked up in huge deposits on continental shelves.
