WebJun 14, 2024 · Winski and his colleagues measured salt concentrations in more than 70,000 samples of the South Pole ice core, which allowed them to estimate how Antarctic sea ice has grown and shrunk over every summer and winter for the past 11,000 years. They found sea ice in the Southern Ocean has been steadily increasing since about 10,000 years ago. WebAug 10, 2024 · The researchers found that the edge of the ice sheet has been shedding icebergs faster than the ice can be replaced. This surprise finding doubles previous estimates of ice loss from Antarctic’s floating ice shelves since 1997, from 6 trillion to 12 trillion metric tons.

WebRoughly 12.4 trillion tons of land-based ice has been lost over the most recent 24 years of data, worldwide (1994-2024). Including all forms of ice everywhere, Earth has lost 28 trillion tons of ice during that same period. If all of the world's land-based ice melted, global sea levels would rise by about 66 meters (216 feet). WebMar 14, 2024 · In 2024, Antarctic sea ice reached its annual minimum on February 21. At 1.79 million square kilometers (691,000 square miles), it was the lowest extent on record.
