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.

You seem to have a bee in your bonet about climate change again.  Is the evidence mounting starting to waver your stuborness.

The more obscure blogs you find, the stupider you look.

Try referencing a scientific organisation for a change.

;D

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.

Why do you consider this news as being so significant? Climate models show that the Antarctic will not begin to warm significantly until long after the rest of the world - because Antarctica is surrounded by very cold oceans. Warming occurring, as projected, in the northern hemisphere, which is largely landmass. Warming that is being observed at an alarming rate over the Arctic right now, causing events like the alarming melt over Greenland the other day.

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

I don't think you get my point. No-one has ever said Antarctica should be warming significantly yet. So why do you think this paper is so significant that you had to start a thread stating that Antarctica hasn't warmed in 500 years?

Oh, and how does Antarctica not warming in 500 years fit with your image of the MWP being a globally significant event? ;D

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

MWP was further away than 500 years.

progs can't look his children in the eye!

His only rebuttal is that looking hcildren in the eye makes you a paedo or that children have two eyes....

Lol, he is so embarrassed!!

Hope he's getting paid with some good drugs or something!!

  ;D ;D ;D

Trying to chew up the entire internet address space probably deserves more than a kick in the head...!!  ;D ;D ;D

Models engineered this world dood!

Without models there would be no internet, let alone the physics that it sits upon!!

models allow experimentation and further mdelling..........

Lol, it's called feedback or itterative technique!! progs doesn't undertsant the first thing about science!

"CAN I HAVE SOME CRACK NOW???????????????????????????????????????????????????????????

PLEASE DAD, I WILL TELL EVERYONE THAT COMES THRU THE DOOR ABOUT PETER COSTELLOES COSMIC REALTIONSHIP WITH INTEREST RATES................!"  :D :D :D :D :D :D

I am very glad the temperatures have not increaded.

... 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.

That is good for the climate.
