Australian scientists drilling for world's oldest ice

Australian scientists are joining other countries, including the UK, in a search to find the oldest ice on earth, deep beneath Antarctica.

Ice traps small amounts of air when it freezes, giving scientists a record of the makeup and temperature of the earth's atmosphere over hundreds of thousands of years.

Now, in an international collaboration, scientists hope to go back a million years.
