Actor Liam Neeson takes on the role of ‘ice’ in the latest in a series of short films about the importance of nature.

The film, produced by charity Conservation International, aims to highlight the plight of the important and threatened ice caps, ice sheets and glaciers in the face of climate change and rising temperatures.

It is the latest in the series of ‘nature is speaking’ films, first launched in September 2014 and narrated by Hollywood stars, including Harrison Ford, voicing the ocean, Julia Roberts as Mother Earth and Robert Redford as the redwood tree.

Speaking about his role, Neeson said: “Climate change is one of the greatest threats facing humanity today. Ice is trying to send us a message. Giving ice a voice was an opportunity I had to seize – before it melts away.”

Conservation International warns that rising temperatures are accelerating the melting of ice in Greenland, Antarctica and the Arctic and glaciers across the world, contributing to sea level rises and putting millions of people’s lives and livelihoods at risk.

In the film, Neeson describes how ice keeps the planet cool – or used to, but humans have taken decades to notice what they are doing to nature.

“Humans keep warming the planet. I try to warm you, I send pieces of me thundering into the ocean, you do nothing. I raise sea levels, you do nothing,” he says.

It is released in the run-up to UN climate talks in Paris, where countries aim to agree a deal to curb the greenhouse gas emissions which drive rising temperatures, and Conservation International argues parts of nature, such as forests, are a powerful force for tackling climate change.
