Antarctic summer ice melting is at its fastest in 1,000 years.

PA: “Summer ice is melting at a faster rate in the Antarctic peninsula than at any time in the last 1,000 years, new research has shown. The evidence comes from a 364-metre ice core containing a record of freezing and melting over the previous millennium.”“Layers of ice in the core, drilled from James Ross Island near the northern tip of the peninsula, indicate periods when summer snow on the ice cap thawed and then refroze. By measuring the thickness of these layers, scientists were able to match the history of melting with changes in temperature.”
