Antarctica sets new record for sea ice
Posted on June 29, 2014 by Harold Ambler
Antarctic sea ice has set a new all-time record maximum over the weekend of June 28-29, 2014.
The sea ice surrounding Antarctica, which, as I reported in my book, has been steadily increasing throughout the period of satellite measurement that began in 1979, has hit a new all-time record high for areal coverage.
The new record anomaly for area is 2.074 million square kilometers and was posted for the first time by the University of Illinois at Urbana-Champaign’s The Cryosphere Today early Sunday morning.
It was not immediately apparent whether the record had occurred on Friday or Saturday. Requests for comment to Bill Chapman, who runs The Cryosphere Today, were not immediately returned.
The previous record anomaly for Southern Hemisphere sea ice area was 1.840 million square kilometers and occurred on December 20, 2007.
Global sea ice area, as of Sunday morning, stood at 0.991 million square kilometers above average.
Although early computer models predicted a diminishment of both Northern Hemisphere and Southern Hemisphere sea ice due to anthropogenic global warming, subsequent modeling has posited that the results of warming around Antarctica would, counter-intuitively, generate sea ice growth.
A freshening of the waters surrounding the southernmost continent as well as the strengthening of the winds circling it were both theorized as explanations for the steady growth of Antarctica’s sea ice during the period of satellite measurement.
A number of prominent climatologists have discounted the growth of Antarctic sea ice, arguing that it is less significant to global circulation than ice in the Arctic basin.
Walt Meier, formerly of the National Snow and Ice Data Center and currently of NASA’s Goddard Institute for Space Studies, has previously said that Antarctic sea ice, which has little ice that survives year to year, is less significant than Arctic sea ice to the climate system.
“While the Arctic has seen large decreases through the year in all sectors, the Antarctic has a very regional signal – with highs in some areas and lows in others,” Meier said in 2013. “And of course, the Arctic volume is decreasing substantially through the loss of old ice. The Antarctic, which has very little old ice, hasn’t much of a volume change, relatively speaking.”
The steady growth of Antarctic sea ice and its influence on global sea ice appeared to provide a public relations problem for those warning of global warming’s menace. According to Meier and some other climatologists, global sea ice area is simply not a metric to consider when examining the climate system.
“A plot of global sea ice is just not informative or useful,” Meier said.
Global sea ice, during the course of the last year and a half, has seen its most robust 18-month period of the last 13 years, maintaining, on average, a positive anomaly for an 18-month period for the first time since 2001.
Phil Jones, of the Climatic Research Unit at the University of East Anglia, waded into the global sea ice analysis in 2013 as well.
“Adding the Arctic and Antarctic sea ice extents doesn’t make that much sense as the two regions are at opposite ends of the world, and the seasons are opposite,” Jones said at the time.
As I also reported in Don’t Sell Your Coat, the temperature at the South Pole has been declining during the past four decades as well.

Like all the climate skeptics with whom I’m acquainted, being a skeptic has had negative financial consequences for my family. Please consider donating to make it possible for me to complete writing my second book about climate cycles.

@RyanMaue I was planning on staying inside anyway, lol. Meanwhile, U.S. migration during era of AGW terror has been toward the south. 1 day ago

Good to know someone benefited from #HannibalSuarez fiasco, I guess. Bet oddsmaker wishes he had this one back, lol espnfc.com/fifa-world-cup… 3 days ago
Maybe #Suarez thought he was living in a dream, i.e. with no witnesses? Quite a few people normally see #WorldCup games. #WaveByeBye 4 days ago
