An ambitious project to retrieve a continuous record of Earth’s atmosphere and climate stretching back 1.5 million years is officially “go”. A European consortium will head to Antarctica in December to begin the process of drilling deep into the continent’s eastern ice sheet. The group’s aim is to pull up a frozen core of material almost 3km long.
Scientists hope this can lead them to an explanation for why Earth’s ice ages flipped in frequency in the deep past.
