Hi Bill, : https://www.nasa.gov/content/goddard/antarctic-sea-ice-reaches-new-record-maximum
Notice this information is from NASA, the same outfit that's measuring cow burps and farts.
Great article - here are some key quotes from the page you linked:
"Editor’s note: Antarctica and the Arctic are two very different environments: the former is a continent surrounded by ocean, the latter is ocean enclosed by land. As a result, sea ice behaves very differently in the two regions. While the Antarctic sea ice yearly wintertime maximum extent hit record highs from 2012 to 2014 before returning to average levels in 2015, both the Arctic wintertime maximum and its summer minimum extent have been in a sharp decline for the past decades. Studies show that globally, the decreases in Arctic sea ice far exceed the increases in Antarctic sea ice."
"“The planet as a whole is doing what was expected in terms of warming. Sea ice as a whole is decreasing as expected, but just like with global warming, not every location with sea ice will have a downward trend in ice extent,” Parkinson said."
"Since the late 1970s, the Arctic has lost an average of 20,800 square miles (53,900 square kilometers) of ice a year; the Antarctic has gained an average of 7,300 square miles (18,900 sq km). "
It's key to note that Antarctica has ice surrounding a continental landmass, so it takes a relatively small amount to increase the extent of the coverage (or to decrease it, of course) as it's only ranging beyond the land and not the entire area.
