Ice on Fire is a 2019 documentary which explores the potential extinction level event caused by arctic methane release, and the newly developed technologies that could reverse global warming by sequestering carbon out of the atmosphere.

Screen Daily praised the film, stating: "Given humanity’s alarming capacity for tuning out the stuff with which it doesn’t want to engage, this slick documentary, which coats its doomsday scenario pill with a sugaring of science as saviour, might be the best chance yet to bring the message to the broader population.

The film, which debuts on HBO on June 11, should be essential viewing for anyone who plans to carry on living on the planet; its approach, while never patronising or simplistic, manages to convey the scientific basics in a way which should not be entirely alienating to a lay audience.

"[8] The Hollywood Reporter Cannes review praised the film, stating: "...as a beginners' guide to Arctic thaw and its consequences, this is pretty exemplary stuff.

Instead of anchoring the explanation around a dominant, often onscreen TED-talk-cum-storyteller like campaigner Al Gore or naturalist David Attenborough, Ice on Fire keeps the narration (only heard) from DiCaprio to a judicious medium, bedding it over high-definition footage, often shot with drones or using time-lapse techniques, under the direction of cinematographer Harun Mehmedinovic.
