Thursday, October 25th, 2007 -- A group of scientists in Britain are warning that global warming could wipe out more than half of the earth's species in the next few centuries. That finding appears in a new study published by researchers at the University of York. Scientists examined the relationship between climate and extinction rates over the past 500 million years. They determined that rising temperatures caused three of the earth's four biggest periods of mass extinctions.

Today, we spent the hour with one of the world's leading scientists studying climate change. His name is Tim Flannery. He is an Australian mammologist and palaeontologist. As a field zoologist he has discovered and named more than thirty new species of mammals. He has been described as being in the league of all-time great explorers such as David Livingstone. Here in this country, Tim Flannery might be best known as the author of the bestselling book "The Weather Makers: The History and Future Impact of Climate Change." Earlier this year he was named 2007 Australian of the Year. Tim Flannery joins me here in Santa Fe, New Mexico.
