Climate Change seems like an endless debate. With evidence coming from both sides of the divide. It is not hard to get confused and just want some straight facts. I have read James Delingpole’s Watermelons book which had some good, hard facts in it, helped massively by the scandal involving scientists and their hacked emails. Climategate certainly did global warming no favours.

But now climate change has a new big hitter on its side: National Geographic photographer James Balog. After all, seeing is believing and James Balog’s photography of melting icebergs cannot be dismissed. In fact, after telling a friend about the documentary he told me of a friend who had trained for two years to go to the North Pole and then could not because the ice had all melted and it was not possible to get there on foot. Worrying stuff.

Now to the documentary. First thing is first: wow. The documentary is beautiful. Balog’s photography is just striking and perfect. His photography ends up on the front cover of the National Geographic. It is fair to say that he might be the best nature photographer working today. However, this is not the only point of Chasing Ice. The point of Chasing Ice is the melting icebergs. Despite knee operations and health problems Balog kept returning to the Arctic and launched the EIS: Extreme Ice Survey. In the eight years since he started the project- in 2005- the icebergs had severely melted, if not disappeared altogether.

Chasing Ice was shortlisted for an Oscar and grossed over $75,000 at the box office in the UK alone. This is all with good reason, Chasing Ice is a brilliant documentary. A must see for everyone and possibly the most important documentary of out time.

Chasing Ice is out now . Join the EIS: Extreme Ice Survey if you would like to help.
