New Zealand scientists are planning to drill nearly a kilometre through Antarctic ice and into the earth below, in a bid to answer how much warming the ice sheet can withstand.

Analyses will help to reveal how far the West Antarctic Ice Sheet retreated in the past — and what it might do in the future.
Scientists have just got their hands on a 228-metre (748-foot) core sample from the muddy bedrock beneath West Antarctica’s chunky ice sheets. Inside the record-breaking sample, they discovered fossils of marine organisms that date from a time when this area was an open, ice-free ocean.
