Climate change: Snakes tell a torrid tale

Matthew Huber1

Top

The discovery in Colombia of a giant species of fossil snake is news in itself. But a wider, more controversial inference to be drawn is that tropical climate in the past was not buffered from global warming.

As the world uneasily eyes a warmer future, a large community of researchers is investigating the past for the insights it might provide into the likely magnitude of climatic and ecological change. Time intervals in Earth's past, such as the early Palaeogene (between 65 million and 40 million years ago), are known to have been much warmer than today.
