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.

And here I was thinking peer-review meant science. I could be wrong, but you would have to come up with a better argument to abandon peer-review.

Abstract.

Increasing paleoclimatic evidence suggests that the Little Ice Age (LIA) was a global climate change event. Understanding the forcings and associated climate system feedbacks of the LIA is made difficult by the scarcity of Southern Hemisphere paleoclimate records. We use a new glaciochemical record of a coastal ice core from Mt. Erebus Saddle, Antarctica, to reconstruct atmospheric and oceanic conditions in the Ross Sea sector of Antarctica over the past five centuries. The LIA is identified in stable isotope (δD) and lithophile element records, which respectively demonstrate that the region experienced 1.6 ± 1.4 °C cooler average temperatures prior to 1850 AD than during the last 150 yr and strong (>57 m s−1) prevailing katabatic winds between 1500 and 1800 AD. Al and Ti concentration increases of an order of magnitude (>120 ppb Al) are linked to enhanced aeolian transport of complex silicate minerals and represent the strongest katabatic wind events of the LIA. These events are associated with three 12–30 yr intervals of cooler temperatures at ca. 1690 AD, 1770 AD and 1840 AD. Furthermore, ice core concentrations of the biogenic sulphur species MS− suggest that biological productivity in the Ross Sea polynya was ~80% higher prior to 1875 AD than at any subsequent time. We propose that cooler Antarctic temperatures promoted stronger katabatic winds across the Ross Ice Shelf, resulting in an enlarged Ross Sea polynya during the LIA.

Models. lol because they have been right. Get over yourself. Failed models, my goodness, lets follow failed models.

So there is no global warming then. It is just less localised in some area's.

MWP was further away than 500 years.

Models engineered this world dood!

... but you like the modelled temperatures based on the deuterium proxy? right? - you know, the ones that indicate that Antarctic temperatures  have not changed significantly in 500 years.

As Upton said, nobody has ever claimed any differently.
