Climatologists have started to drill into the oldest ice core in Antarctica to find some air that may have been there around 1 million to 900,000 years ago. The teams are from Australia, China, and Europe in a friendly type competition to find samples of air that is about 1.5 million years old. They would like to find out what […]
