Scientists construct 800,000 year old climate record

Scientists have produced their version of how Greenland’s climate might have looked over the last 800,000 years.

Using drill cores taken from Greenland’s ice sheets they have found that Earth’s climate is capable of rapid transitions.

Previously, temperature records from Greenland have covered only the last 100,000 years or so. By utilising the longer ice core temperature record retrieved from Antarctica and a mathematical formulation they have been able to extend the Greenland records.
