Radio Times: Review by:; David Butcher

“We know more about what happens on the Moon surface than what goes on inside the ice,” sighs a scientist standing on a massive glacier in Greenland.

Those plumbing secrets of glaciology are the unlikely subject for this spectacular two-part special. To compensate for any perceived slowness in the subject matter, it’s an all-action affair, with scientists and film-makers camping on a headland, diving into fabulous indigo lakes, swooping in on helicopters, patrolling the glacier front in a research boat, and so on.

This is a dangerous business, as the voiceover keeps reminding us (“It’s extremely hazardous... They’re playing Russian roulette” etc), but the shots of vast slabs “calving” off the face of the glacier are well worth the effort. Chris Packham and Helen Czerski lead the icecapades. Concludes Thursday.
