Ancient ice discovered high in Tibet may be more than 128,000 years old, preserving an extraordinary record of Earth's climate that scientists previously thought had been lost. The discovery reveals a rare glimpse into the last ice age and could reshape our understanding of how glaciers survive dramatic changes in global climate.

Read the story →Scientists have uncovered a surprising connection between Earth's opposite poles that may help explain how the planet plunged into past ice ages. New research suggests that as massive ice sheets expanded across the Northern Hemisphere, they cooled Atlantic Ocean waters that eventually traveled south toward Antarctica. This cooling may have disrupted Southern Ocean circulation, allowing the ocean to absorb and store more carbon dioxide from the atmosphere, further cooling the planet.

Scientists discovered that warm ocean water is penetrating miles beneath the ice, weakening its foundations and accelerating its retreat. A new model predicts that the glacier could add up to 30 millimeters to global sea levels by 2100, with a 60% chance of losing a crucial stabilizing ridge.

Read the story →Arctic winter sea ice could disappear much faster than scientists previously expected, according to new research using climate clues from 6,000 years ago. By comparing ancient ocean sediments with modern climate models, researchers found that future winter ice coverage may be roughly one million square kilometers smaller than earlier predictions suggested.

Read the story →Switzerland’s glaciers are disappearing at an alarming rate, losing more than 5% of their ice volume in 2026 alone. Some of the country’s most famous glaciers experienced their worst melting on record, while several smaller glaciers vanished completely. Nearly 20% of Switzerland’s glacier ice has disappeared in just five years, driven by unusually snowless winters and extreme summer heat.
