A paper published today in Climate of the Past shows no increase in temperature of the Ross Ice Shelf, Antarctica over the 536 year period from 1470-2006. The paper, based upon a temperature proxy from stable isotopes of deuterium [δD] in ice cores, finds that the Little Ice Age prior to 1850 was about 1.6C cooler than the last 150 years. Smoothed proxy temperatures at the beginning of the ice core record in 1470 indicate slightly higher temperatures than at the end of the record in 2006. Climate alarmists claim the poles are the "canaries in the coal mine" and warm the fastest, however, this data shows Antarctica, home of 90% of the world's ice, has not warmed over the past 500+ years.
