Antarctica Was Once a Rainforest. What Happened?

In November 1912, a search party found Captain Scott's tent on the Antarctic ice. On the sledge outside lay about 35 lb of rock that the dying men had hauled all the way from the Beardmore Glacier. Inside those rocks were fossil leaves of Glossopteris — the first clue that the coldest continent on Earth was once covered in forest. This documentary follows that clue through a century of science: Permian forests that grew in months of polar darkness ~260 million years ago, a 90-million-year-old rainforest found in a drill core under the seabed of West Antarctica, the new 2026 evidence that those forests near the South Pole regularly burned, and the palms that grew on the Antarctic coast ~52 million years ago — before the ice arrived about 34 million years ago.

RECONSTRUCTION No AI-generated images or video are used in this film. Archive photos and film are from the British Antarctic (Terra Nova) Expedition 1910–13. Man-hauling and tent scenes in Herbert Ponting's film were filmed as demonstrations near the expedition base in 1911, not on the polar journey itself; they are labelled on screen. The forest painting is an artist's reconstruction by James McKay (CC BY 4.0). Photos of peat fires, bogs and Huon pine are modern analogues and are labelled as such.
