What does Antarctic ice reveal about CO2 and climate shifts?

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.
