    › View 1980 image › View 2012 image This interactive illustrates how perennial sea ice has declined from 1980 to 2012. The bright white central mass shows the perennial sea ice while the larger light blue area shows the full extent of the winter sea ice including the average annual sea ice during the months of November, December and January.

    Ice sheet layers can be read like the pages of a book - if you know the language. In this video, we see how scientists are deciphering the history of Earth's climate from ice cores taken from western Antarctica Snow that is compressed into ice forms distinct layers.

    Layers of frozen sea water, known as sea ice, cap the Arctic Ocean. The ice grows dramatically each winter, and melts just as dramatically each summer. In the past decade, the melting has grown more dramatic, while growth has become less so, as you can see in our World of Change feature.

    If you want to see global warming's signature, look to the Arctic. Up north, the air is warming and the ice is melting. As all of that reflective ice goes away, the Arctic Ocean is soaking up more sunlight, further enhancing warming. Melting Arctic ice is also contributing significantly to sea level rise.

    A RACE is on to retrieve the first million-year-old sample from deep within Antarctica's ice. It's a prize that could help us understand what drives major changes in Earth's climate.

    Europe's Cryosat mission is now watching the ebb and flow of Arctic sea ice with high precision. The radar spacecraft was launched in 2010 to monitor changes in the thickness and shape of polar ice. Scientists have spent the past two years getting to grips with its data.
