An international group of scientists who work with satellite data say the acceleration in the melting of Earth's ice sheets is now unmistakable. Melting in Antarctica has been happening predominantly in its peninsula region - the finger of land that extends towards South America - and in the west of the continent where its ice margin is being eaten away from below by relatively warm ocean waters. "Accelerating ice sheet losses mean we're looking in the next decade at a marked rise in the rate of sea-level rise," said Prof Andrew Shepherd, from Northumbria University and the founder of Imbie
