During a Q&A discussion about climate change, Tasmanian Senator Jacqui Lambie said it was four degrees hotter 110,000 years ago. Is that right?
A new millennium-long record reveals that Australia has suffered longer droughts and wet periods than those recorded in the past century's weather observations.
Ice cores tell us vital information about how the world's climate has changed - and how it will change in the future.
Ice cores are cylinders of ice drilled from glaciers and ice sheets. When snow falls it takes with it a record of many aspects of the atmosphere. As long as no melting takes place, this information is…
How can air bubbles trapped in ice for millions of years, or fossilised fern fronds, or the chemical make-up of rocks that were underwater in the distant past provide us with an inkling of our future…
The past is the key to the future. When snow falls on polar ice sheets, in Greenland and Antarctica for example, air is trapped between the snowflakes. Year after year, the snow compacts under its own…
A 364-metre-long ice core record has revealed an unusual pattern of rapid warming across the Antarctic Peninsula over the…
