Что заморозило зелёную Антарктиду

What froze green Antarctica Hidden beneath two kilometers of Antarctic ice is a warm forest with dinosaurs. 🧊 What geological moment froze an entire continent? Ninety million years ago, back in the Cretaceous Period, a warm rainforest grew on the site of the South Pole—with an average annual temperature of about twelve degrees, similar to New Zealand today. Dinosaurs walked across it, and the trees endured a four-month polar night. This green world—ancient, warm Antarctica—endured for tens of millions of years and even survived the extinction of the dinosaurs. And about thirty-four million years ago, at the transition between the Eocene and Oligocene periods, the continent froze almost instantly. We examine the scientists' investigation: what froze Antarctica—the Drake Passage and the Circumpolar Current from textbooks, or a drop in carbon dioxide levels below a critical threshold. Paleoclimate, glaciation, geology, and paleontology in a single corollary. Why climate scientists rewrote textbooks—and what Antarctica's ancient catastrophe reveals about our future. For more evidence-based science without the mysticism, subscribe to Veritora. If the Drake Passage is innocent, should we trust the other "obvious" answers from school textbooks?
