We've made a few changes, but apologies if you've watched the video already! In this video, we’re travelling back to Earth's frozen past, to discover what our planet was like during the Ice Age. What massive creatures dominated these icy landscapes, and what caused their extinction? We'll also ask a chilling question: could it happen again? Join us as we explore the rise and fall of Earth's frozen past and look for the warning signs of its return. ▀▀▀▀▀▀ To stay on top of space news, sign up to the Astrum newsletter: https://astrumspace.kit.com Astrum Displate Posters: https://displate.com/artist/astrumspace?art=5f04759ac338b Astrum Merch: https://astrum-shop.fourthwall.com/ Join us on the Astrum discord: https://discord.gg/TKw8Hpvtv8 A huge thanks to our Patreons who help make these videos possible.
