    The US space agency, NASA, yesterday released brand new images showing the pace of ice loss from Earth's two vast ice sheets, Greenland and Antarctica.
    The amount of ice lost from the frozen expanses at the very north and south of the planet is accelerating, say the scientists, and together have helped raise global sea level by more than 7cm since 1992.

    The Greenland ice sheet covers approximately 1.7m square kilometres (660,000 square miles), an area almost as big as Alaska. At its thickest point, the ice sitting on top of the land is more than 3km deep.
    Since 2004, Greenland has been losing an average of 303bn tonnes of ice every year, according to NASA data, with the rate of loss accelerating by 31bn tonnes per year every year.
    In the animation below, red shows areas that have lost ice, blue shows areas that have gained ice.
