Antarctic Ice Shelf Collapse: A Drop in the Ice Bucket?

Last week the first story I heard while turning on the TV was about a portion of the Antarctic ice shelf collapsing. As usual the newscaster read this story in somber tone while citing unnamed scientists who claim this is further proof of alarming global warming, caused by humans of course. Below is an excerpt of an analysis from ICECAP.

Misleading Reports About Antarctica
By Joseph D’Aleo,

Last year when Antarctic set a new record for ice extent, it got no
media attention. They focused on the north polar regions where the ice set record low levels. This summer when unprecedented anomalous cover continued in the Southern Hemisphere again no coverage. Then this report in the news today. You probably saw it on your favorite network or internet news site (pick one, anyone).

Icecap Note: Let’s put this in perspective. The account may be
misinterpreted by some as the ice cap or a significant (vast) portion is
collapsing. In reality it and all the former shelves that collapsed are small and most near the Antarctic peninsula which sticks well out from Antarctica into the currents and winds of the South Atlantic and lies in a tectonically active region with surface and subsurface active
volcanic activity. The vast continent has actually cooled since 1979.

The full Wilkins 6,000 square mile ice shelf is just 0.39% of the
current ice sheet (just 0.1% of the extent last September). Only a small portion of it between 1/100th-1/200th of Wilkins has separated so far, like an icicle falling off a snow and ice covered house. And this winter is coming on quickly. In fact the ice is returning so fast, it is running an amazing 60% ahead (4.0 vs 2.5 million square km extent) of last year when it set a new record. The ice extent is already approaching the second highest level for extent since the measurements began by satellite in 1979 and just a few days into the Southern Hemisphere fall season and 6 months ahead of the peak. Wilkins like all the others that temporarily broke up will refreeze soon. We are very likely going to exceed last year’s record. Yet the world is left with the false impression Antarctica’s ice sheet is also starting to disappear.
