The Smithsonian know there’s more ice, but can’t tell you why, except it’s global warming. Maybe it’s “chilled water and slushy ice”?
Really, you don’t know why?
They don’t want to know, it isn’t part of the pocket-lining agenda:
[…] The difference between Antarctica’s sea ice trend and the global ones amount to the difference between weather and climate. While researchers don’t know exactly how southern sea ice can be covering a greater area in Antarctica while the sea around it warms, they have some ideas. It might be because wind patterns have created a chilled water and slush mixture primed to form ice or because of changes in ocean currents. All those explanations are variations in weather.
Part of the seemingly counterintuitive nature of this observation is just a failure to really look at the big picture: “The planet as a whole is doing what was expected in terms of warming,” says Claire Parkinson, a scientist at NASA’s Goddard Space Flight Center, in a statement back in October, when the Antarctic sea ice first set a record maximum. “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.”
Take a step back and look at the world as a whole—you’ll see that the Arctic is rapidly losing sea ice. While this puts the South and North poles on apparently different trajectories, the overall loss is greater than the gain. Bad news for the polar bears…and probably the rest of us as well.
Another thing, the Arctic is NOT rapidly losing sea ice. A figment of their imagination. (my bold)
The Arctic ice is now the same extent as a decade or more ago: http://wattsupwiththat.com/reference-pages/sea-ice-page/
