'Antarctic winter record cold'

While new 'local' records are fun, they're not 'global', and Vostok Station, if this is where the new record was set, has been the 'coldest' place on Earth since 1983 ( 129-F below ).
-------------------------------------------------------------------------------------
The issue with the climate is, summer temps at the Western peninsula.
The poles are warming faster than anywhere else on the planet.
Between 1900, and 2006, Earth's warmed, from 56.58-F, to 57.99-F.
The Arctic has seen as high as 36-degrees above 'normal.' It IS that fastest-warming area.
--------------------------------------------------------------------------------------
Antarctica, while seeing up to 43-F above 'normal, statistically ( temporally ) remains in second place.
* In the summer, the 0-degree C line continues to move south, bring above-melting temperatures.
* Tropical sea-surface temperatures have increased by 5-C, to 9-C.
* Currents bring tropical heat beyond the Circumpolar Current south.
* Circumpolar Deep Water Gyre is delivering warm water to the bottom of the ocean, at the ice-cap grounding lines, melting the glaciers from below, creating suture zones; fractures which are a setup for glacier collapse.
* Ice, which might accumulate in the winter can't, due to foehn winds, which blows the snow off the continent, before it has a chance to compact.
* In 2012, Antarctica lost the equivalent of 41.8-trillion 10-pound bags of ice, equaling 26,410,564,230,000-gallons of freshwater diluting the seawater salt content. ( I'm not saying it will shut down the Atlantic Thermohaline Conveyor [ The Day After Tomorrow ], but of you wanted to do that, this would be how you'd pull that off ).
-------------------------------------------------------------------------------------
By 2006, Earth surpassed the temperature of the Eemian Period, 120,000-years ago, when the last ice age ended, and sea level was 20-feet, to 30-feet higher, depending on currents. This sea level rise is already 'baked-in', even if we were to stop producing all anthropogenic greenhouse gases.
-------------------------------------------------------------------------------------
Winter temperature down there doesn't affect 'climate change.'
You can think of Antarctica as an ice cube, the size of the United States and Mexico, combined, two-miles thick.
