United KingdomScientists have identified why Antarctica became covered in ice millions of years earlier than the Arctic, despite Earth being significantly warmer at the time. The study, published in Science, reveals that geological processes during the Jurassic period caused parts of East Antarctica to rise, creating elevated terrain that allowed ice accumulation. This uplift, driven by 'mantle waves' beneath the continent, enabled the formation of the massive East Antarctic Ice Sheet 34 million years ago. The research involved multiple institutions across Europe and used computer simulations to model landscape changes over 100 million years. The findings help explain how such a large ice sheet could develop in a relatively warm climate.
