...Jacquet returns to the Antarctic to tell the life story of climatologist Claude Lorius, now in his 80s, who has spent his life drilling out ice cores at enormous depth, and whose resulting analysis proved key in linking climate change and “greenhouse” gases.
Jacquet presents his film very much as a head-on challenge to climate change deniers: by simply talking us through Lorius’s career, and the progress of his work, we understand the methodical processes by which he came to his conclusions. Essentially, it’s a rebuttal to background-noise deniers’ complaints about flawed science: Lorius says what he found, and what it means, with calm, unflappable detachment.The author concludes his review with this statement:
Jacquet’s film is ... a call to arms to the environmental movement destabilised and buffeted by the denial industry. Ice and the Sky ends with a direct challenge to the viewer: “Now that you know, what are you going to do?” What, indeed. This is a powerful testament, and one that ought to have a considerable impact.
