According to a recent study by sea ice scientists Claire Parkinson and Dona=
ld Cavalieri of NASA's Goddard Space Flight Center, Antarctic sea ice incre=
ased by roughly 17,100 square kilometers per year from 1979 to 2010. Much o=
f the increase, they note, occurred in the Ross Sea, with smaller increases=
 in Weddell Sea and Indian Ocean. At the same time, the Bellinghausen and A=
mundsen Seas have lost ice. "The strong pattern of decreasing ice coverage =
in the Bellingshausen/Amundsen Seas region and increasing ice coverage in t=
he Ross Sea region is suggestive of changes in atmospheric circulation," th=
ey noted.

"The year 2012 continues a long-term contrast between the two hemispheres, =
with decreasing sea ice coverage in the Arctic and increasing sea ice cover=
age in the Antarctic," Parkinson added. "Both hemispheres have considerable=
 inter-annual variability, so that in either hemisphere, next year could ha=
ve either more or less sea ice than this year. Still, the long-term trends =
are clear, but not equal: the magnitude of the ice losses in the Arctic con=
siderably exceed the magnitude of the ice gains in the Antarctic."

On their Arctic Sea Ice News and Analysis blog, scientists from the Univers=
ity of Colorado wrote: "Comparing winter and summer sea ice trends for the =
two poles is problematic since different processes are in effect. During su=
mmer, surface melt and ice-albedo feedbacks are in effect; winter processes=
 include snowfall on the sea ice, and wind. Small changes in winter extent =
may be a more mixed signal than the loss of summer sea ice extent. An expan=
sion of winter Antarctic ice could be due to cooling, winds, or snowfall, w=
hereas Arctic summer sea ice decline is more closely linked to decadal clim=

Also, bear in mind that climate change is not the same as universal global =

According to NASA

*In late September 2013, the ice surrounding Antarctica reached its annual =
winter maximum and set a new record. Sea ice extended over 19.47 million sq=
uare kilometers (7.51 million square miles) of the Southern Ocean. The prev=
ious record <>
of 19.44 million square kilometers was set in September 2012.*

So the previous record was set in September 2012, the current record was se=
t in September 2013, and It would not be surprised if a new record is set i=
n September 2014 since according to Der Spiegel

*Never before has there been so much ice at this time of year since measure=
ments began.*

This time in the article refers to April 2014.

I assume that you find NASA data credible.

I would encourage you to be at least as skeptical of the sources that suppo=
rt your preferred position as you are those that refute it
