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 1/10th-1/20th 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. [*]

Per farla breve, la verità allora è che il distacco del colossale iceberg, lontano dall'essere la prova che in Antartide i ghiacci stanno diminuendo (come tutte le Agenzie hanno strillato disinformate), esso è invece la conseguenza del fatto che, lì, i ghiacci, sono aumentati come non mai.
