Ancient Ice Core Discovered in Antarctica
Scientists have drilled a 1.2-million-year-old ice core from Little Dome C in Antarctica, advancing climate research. Extracted at a depth of 2.8 km, this core provides data on historical atmospheric conditions and greenhouse gas concentrations. Part of the Beyond EPICA project, it reveals current carbon dioxide levels are 50% higher than historical maxima. Using isotope analysis, researchers dated the ice accurately. Insights from this core enhance our understanding of Earth’s climatic past, aiding future climate predictions. The project marks a milestone in studying long-term climate changes, with implications for global conservation and climate policy.
