\u201dAntarctica wasn\u2019t always a frozen wasteland. It wasn\u2019t until around 34 million years ago that the first small glaciers formed on the tops of Antarctica\u2019s mountains. And it was 20 million years later, when world-wide temperatures dropped by 8 \u00b0C, that the glaciers\u2019 ice froze onto the rock, and the southern ice sheet was born.\u201d
