Chasing Ice review

There can't be many people still resistant to the inconvenient truth of climate change.

But any that are should be made to see Jeff Orlowski’s eco-doc, which charts the efforts of National Geographic photographer James Balog to film time-lapse imagery of glacial retreat.

As this heroic campaigner battles harsh conditions and a bum knee to install 30 cameras across three continents, some may ask whether it’s worth the trouble.

They’ll soon be silenced by the jaw-dropping results: visually spectacular montages of ice floes receding that will make you gasp and move you to tears.
