  Image © Shutterstock Swiss scientists from the University of Bern are hoping that a 3 km long cross-section of Antarctic ice could reveal new information about climate change throughout the Earth’s history. Over the ages, built-up snow and air have been compressed into thick layers of ice that serve as a permanent record of global temperatures and the amount of greenhouse gasses in the atmosphere. Researchers believe that a new expedition would be able to extract ice cores dating back 1.5 million years, almost twice as far back as the current oldest samples, which extend 800,000 years.
