DIRECTOR'S CUT: In recent years climate science has come under increasing attack, so concerned geologist Simon Lamb grabbed his camera and set out to explore the inside story of climate research. For over three years he followed scientists from a wide range of disciplines at work in the Arctic, Antarctic, Southern Ocean, New Zealand, Europe and the United States.

They talk about their work, their hopes and fears with a rare candor and directness, resulting in an intimate portrait of the global community of researchers racing to understand our planet’s changing climate and provide a compelling case for rising CO2 as the main cause.

This is the human voice of climate science, making the issue easier for the wider public to appreciate. The scientists represent all key areas and come from many backgrounds. Their conclusion is being borne out by a growing global consensus represented by the 2015 Paris Agreement aimed at reducing carbon emissions.
