World's oldest Antarctic ice being melted to find out more about climate

#BBCNews

An ice core that may be older than 1.5 million years is being melted down by scientists to unlock vital information about Earth's climate.

The glassy cylinder is the planet's oldest ice and was drilled from deep inside the Antarctic ice sheet.

Frozen inside is thousands of years of new information that scientists say could "revolutionise" what we know about climate change.
