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?
most recent report from Intergovernmental Panel on Climate Change (IPCC) said that models for Antarctic sea ice trends are still "incomplete and competing."
