What unprecedented warming?

Andrew Bolt, Herald Sun (Australia)
"Geology journal discusses the recent scare claims about “unprecedented” warming on just one small part of an otherwise cooling continent:

Rapid warming and consequent ice-shelf collapse have focused attention on the glacial record of the Antarctic Peninsula.... Moreover, the data indicate that present reduced ice extent on the western Antarctic Peninsula is not unprecedented and is similar to that experienced during at least three periods in the last 5600 yr."
