Antarctica

The Thwaites Glacier in western Antarctica. (Image credit: NASA) A sweeping new satellite analysis shows that Antarctica has lost nearly 5,000 square miles (12,950 square kilometers) of grounded ice over the past three decades — an area roughly twice as big as Delaware — as warming ocean waters erode the…

Salps are a colonial, barrel-shaped group of species that pump water through their transparent bodies, filtering out even the smallest phytoplankton. Aaron Sanders Published: March 2, 2026 1.05pm CET Melting ice is an emblem of climate change. For sea ice, the Arctic has been grabbing most of the headlines for…

As climate risks accelerate and decisions increasingly depend on trusted data, the global system that observes Earth's climate has never mattered more. From satellites orbiting thousands of kilometres above the planet to research stations in Antarctica, it tracks Essential Climate Variables - including temperature, sea level, greenhouse gases and ice…

A mysterious dip in Earth’s gravity beneath Antarctica traces back to slow-moving rocks deep underground. Gravity feels dependable and unchanging, something we rarely question. Yet the planet behaves in strange ways defies intuition. In reality, gravity is not uniform across Earth’s surface. Its strength shifts from place to place...Read More

Gravity does not pull equally everywhere on Earth. Variations in the planet’s internal structure create measurable differences in how strongly it tugs at the surface. The weakest region lies beneath Antarctica. In a study published in Scientific Reports, researchers show that this continent-scale gravitational low strengthened over tens of millions…
