## Resource

Send us Fan Mail We follow the 2,800-meter Antarctic ice core from Little Dome C to a -50°C lab in University of Bern, tracing how scientists extract ancient air to probe the Mid-Pleistocene transition and the limits of abrupt climate change. The story links field grit, laser sublimation, and CO2 records to the risks facing modern societies. If you would like to see the Antarctic ice in a video and read the collection on this topic, and more stories, please visit Swissinfo Science. Jou...
