The Loose Tooth

Another report by the BBC on Antarctica. This time on the so-called "Loose Tooth", a large calving ice berg.

Once again, the emphasis is on the effects of warming. It's as though ice bergs only calve when the climate is warming. But read more of the article and there would appear to be no obvious climatic driver to the formation of the Loose Tooth. In fact the researches point out that the rift that is opening is more like a geological fault and is responding to internal pressures within the Ice Sheet.

The impression many readers will gain from this and many other such articles is the first "warming" commentary. I would imagine that eyes begin to glaze over at reading the line it comes down to the internal glaciological stress.
