Science Actually @scienceactually.bsky.social · 27/10/2024
Some ice cores contain air bubbles trapped from hundreds of thousands of years ago, preserving tiny samples of the ancient atmosphere. This allows scientists to directly measure past concentrations of greenhouse gases like carbon dioxide and methane.#science #sciencefacts #icecore #ancientatmosphere
