Global Warming Blow-hards and Record Breaking Antarctic Ice


Antarctic Ice is increasing - an unfortunate bit of inconvenient truth for the Climate Change Kooks.  Of course, these knuckleheads explain the phenomenon as a result of Polar Vortex winds (caused by global warming) cooling the planet so much that record ice is being formed.  Yup, that really makes sense to me.

For an unprecedented third year in a row, Antarctica's sea ice is poised to smash a new record this month.

The Southern Hemisphere's unrelenting winds and frigid air froze ocean water into 7.6 million square miles (19.7 million square kilometers) of Antarctic sea ice this southern winter, the National Snow and Ice Data Center (NSIDC) said yesterday (Sept. 16).

With several more weeks of growth to go, Antarctica's sea-ice extent could soar well above the records set in 2012 and 2013. For now, only 88,800 square miles (230,000 square km) separate the 2013 and 2014 high marks.

Sea-ice extent is the total ocean area in which the ice concentration is at least 15 percent, as measured by satellite.


"In the short term, it seems like there hasn't been much ice loss in the past couple of years, but I think it's still very much within the long-term trend of declining sea ice," said Axel Schweiger, chairman of the University of Washington's Polar Science Center in Seattle. "One shouldn't necessarily expect every year to be a record low."

At both poles, sea ice shrinks and expands each year with summer heat and winter cold, though in the Arctic, some ice sticks around each year. These hardy ice floes are called multiyear ice. This year, leftover ice from 2013 played a role in preventing an extreme melt, because multiyear ice is thicker and more resistant to heat than thin, young ice, the NSIDC said. Cooler-than-average sea surface temperatures in much of the region also meant more ice lasted through the summer. "The ice does appear to be quite a bit thicker this year," Schweiger told Live Science.

One region north of Siberia did experience warm seas, which combined with strong winds to open a big bite in the ice. The ice edge retreated north of the Laptev Sea to within 5 degrees latitude of the North Pole (a distance of about 310 miles, or 500 km).

What's up with Antarctica?

Researchers (these are the same bonehads that got stuck in the ice a few months ago as they were investigating vanishing sea ice) think Antarctica's recent record-high ice extents could result from the southern polar vortex blowing closer to the continent as a result of the ozone hole and greenhouse gases. The winds help pack ice more tightly and also shift ocean currents in a manner that drives ice formation. But the most recent report from Intergovernmental Panel on Climate Change (IPCC) said that models for Antarctic sea ice trends are still "incomplete and competing."

  1. Polar bears, coming to a suburban neighborhood near you!

    Weather is weather, it can't be predicted nor in any way completely described. Though attempts at prediction have improved over time, good luck. You cannot tell me with ANY certainty that the mean or average planetary temperature will rise or fall over the next ten years. It's not possible. You can look at trends, but that's all they are is trends. One small parameter can change and send your 'prediction' off to failure land.

  2. Here is an update from the Register (www.theregister.co.uk)

    Climate scientists have confessed themselves baffled - yet again - by another all-time record area of sea covered by ice around the Antarctic coasts.

    "What we're learning is, we have more to learn," said Ted Scambos, lead scientist at the US National Snow and Ice Data Center, announcing the latest annual sea ice maximum for the austral continent. According to the NSIDC:

    Sea ice surrounding the Antarctic continent reached its maximum extent on September 22 at 20.11 million square kilometers (7.76 million square miles). This is 1.54 million square kilometers (595,000 square miles) above the 1981 to 2010 average extent, which is nearly four standard deviations above average. Antarctic sea ice averaged 20.0 million square kilometers (7.72 million square miles) for the month of September. This new record extent follows consecutive record winter maximum extents in 2012 and 2013. The reasons for this recent rapid growth are not clear. Sea ice in Antarctica has remained at satellite-era record high daily levels for most of 2014.

    Climate scientists have been puzzled by the behaviour of the southern ice for many years now. The most commonly used models say that its steady growth should not be happening in a warming world (though the warming of the world is also in doubt, as air temperatures have been steady for the last fifteen years or more - and it turns out that deep ocean temperatures are not increasing either, leaving the "mystery" of the apparent end of global warming "unsolved").

    This failure of reality to match up with climate modelling has, as some eminent climate scientists have noted, had the effect of "limiting confidence in the predictions" of severe warming and associated disasters this century.

    Meanwhile at the other end of the planet the Arctic sea ice has covered lesser areas in recent times. The lowest Arctic area seen in the era of satellite measurements was in 2012, but the three consecutive record-high Antarctic maxima of 2012, 2013 and now 2014 have resulted in global sea ice levels this year and last year coming out pretty much normal. ®

  3. I fully expect to see an announcement that HELL HAS FROZEN OVER due to Global warming.
