Earth is losing more than a trillion tonnes of ice each year. The loss of ice from polar and mountain regions has consequences that are felt all around the world. Ice lost from glaciers, ice sheets and frozen land contributes to sea level rise. ESA is using satellites to measure the amount of the ice lost from each component of the cryosphere. The sooner we stabilise Earth’s temperature, the more manageable its impacts will be.
