Ice Age Approaches? - Antarctic Ice Area Sets Record High
Sept 20, 2012 | Scoop.co.nz
"Day 258 of 2012 is the highest for this date since satellite scanning
of Antarctic ice areas commenced 33 years ago" the New Zealand Climate
Science Coalition announced today. "It is also the fifth highest daily
value on record." Coalition chairman, Hon Barry Brill, says the most
remarkable aspect is the extent to which the 2012 area exceeds normal
Antarctica averages. "The sea ice cover yesterday was 311,000 square
kilometers above the 1979-2012 average. The surplus ice is more than twice the area of New Zealand."
The Antarctic dimensions come partly at the expense of Arctic sea ice,"
said Mr. Brill. "Over the 33-year period aggregate global sea ice
volumes have remained steady, but there are fluctuations between the two
polar areas from year to year.
The fluctuations are the result of ocean currents and wind patterns,
rather than temperatures. Antarctic ice is much more important than that
of the Arctic. The area of its sea ice is a million square kilometers
larger than the highest value ever recorded in the Arctic. Then, of
course, the Antarctic is an entire continent, with more than 90% of the
earth's glacial ice," said Mr. Brill. "It is appropriate that this
record should occur in a week that The Listener carries a cover
story featuring the winter low point of Arctic ice, along with multiple
pictures of calving glaciers and forlorn polar bears," said Mr. Brill.
"The magazine has little to say about the Antarctic apart from
complaining that it is "poorly understood."
The author also avoids mentioning the glaring facts that no
significant global warming has been recorded in the past 16 years, and
that sea level rise is apparently decelerating. "It is
unfortunate that under-informed writers, albeit unwittingly, mislead
their readers who should be helped to understand the difference between
sea ice extent and ice cap ice, both thickness and extent as regards the
latter. The ice cap in the Arctic is small compared to the Antarctic.
The cap of the Antarctic is increasing in thickness in most places,
except around the Antarctic Peninsula. Sea ice extent is largely a
consequence of sea surface temperature, ocean currents and wind," said
Mr. Brill, who advised those interested in graphic confirmation of
Antarctic sea ice readings to refer to this link as well as this link.
