Bedtime reading for the Beebies about how once upon a time there was a theory...- a theory, see? Compare and contrast.

The Beeb:
'Researchers... say 70% of Switzerland's glaciers will disappear in the next 30 years, due to the effects of global warming.'

The alternative view:
'Glaciers have been receding for hundreds of years; that’s because we are still coming out of the very cool period of the Little Ice Age. Ice shelves have been breaking off for centuries. Scientists know of at least 33 periods of glaciers growing and then retreating.
It’s normal.'

Wish we'd hear the alternative sometimes, even if it would spoil the story.
