Ice and the Sky review – a climate change pioneer's passion for Antarctica

This personal and reflective documentary recounts the mission of a pioneering scientist to find evidence of climate change in the ice of the Antarctic

The title of this nature documentary says it all - all about scientific data mined from the Antarctic telling you what is happening up there in the sky or in the air around us. It is the story of the pioneering climate scientist Claude Lorius, now 83, whose lifelong passion for the Antarctic began in his 20s when he signed on for a scientific expedition to that remote region.

Lorius was able to take samples deeper and deeper in the ice, which effectively contained fossilised records of its ambient temperature hundreds or thousands of years ago: the evidence showed an unmistakable upswing in the last century, and Lorius realised that mankind's CO₂ emissions were heating up the atmosphere.
