Scientists Melt World's Oldest Ice Cores for Climate ResearchSaralnama

Scientists at the British Antarctic Survey are melting ice cores from Antarctica. The cores came from 2.8km deep in the ice sheet. They are at least 1.5 million years old. The team works non-stop to study the ice. They must melt the samples to analyze them. This project took years of work and hundreds of people. The ice will give a million-year environmental record. The BBC's Rebecca Morelle is watching the last cores being melted. Today: The oldest ice cores arrive at the lab. From now: Teams work round the clock to melt and study the ice. Until: The last samples are analyzed. Next: Scientists will examine the data to understand Earth's past climate. (Updated 2 Oct 2025, 18:11 IST; source: link)
