"A dramatic warming of the planet 55 million years ago cannot be solely explained by a surge in carbon dioxide levels, a study shows, highlighting gaps in scientists' understanding of impacts from rapid climate change." One implication is that the current warming episode could prove worse than now predicted, as models may not fully account for feedback mechanisms that amplify warming.
