Last Hours

Green World Rising on Sep 19, 2014

The film “Last Hours” is the 2nd film in the Green World Rising Series ( the first one is “Carbon” that is available on this channel). Last Hours describes a science-based climate scenario where a tipping point to runaway climate change is triggered by massive releases of frozen methane. Methane, a powerful greenhouse gas, has already started to percolate into the open seas and atmosphere from methane hydrate deposits beneath melting arctic ice, from the warming northern-hemisphere tundra, and from worldwide continental-shelf undersea methane pools.

Burning fossil fuels release carbon that, principally through greenhouse effect, heat the atmosphere and the seas. This is happening most rapidly at the polar extremes, and this heating has already begun the process of releasing methane. If we do not begin to significantly curtail the use of carbon-based fossil fuels, this freed methane threatens to radically accelerate the speed of global warming, potentially producing a disaster beyond the ability of the human species to adapt.

With this film, we hope to awaken people to the fact that the earth has experienced five major extinctions in the deep geologic past – times when more than half of all life on earth vanished – and that we are now entering a sixth extinction. Industrial civilization with its production of greenhouse gases has the potential to trigger a mass extinction on the order of those seen in the deep geological past. In the extreme, it could threaten not just human civilization, but the very existence of human life on this planet.

An asset for the climate change movement, “Last Hours” will be disseminated globally to help inform society about the dangers associated with climate change and to encourage the world community to chart a path forward that greatly reduces green house gas emissions. We encourage you to explore this website and the highlighted actions you can take to address climate change. We look forward to bringing you additional films about the challenges we face and the solutions that exist over the next few years, in the lead up to COP21, the 2015 UN Conference on Climate Change in Paris.

“Last Hours” is narrated by Leonardo DiCaprio, presented by Thom Hartmann and directed by Leila Conners. Executive Producers are George DiCaprio, Earl Katz and Roee Sharon Peled. Last Hours is produced by Mathew Schmid and was written by Thom Hartmann, Sam Sacks, and Leila Conners. Music is composed and performed by Francesco Lupica. Last Hours is brought to you by the Leonardo DiCaprio Foundation and produced by Tree Media.

  16. The timing of Typhoon Haiyan in the Philippines and the release of “Last Hours” is so coincidental to be eerie. Yes, do disseminate this film and the web address as widely as humanly possible. Post about it, write everywhere about it, send it everywhere…
    Thank you,

  17. Apocalyptic passions are running high.

    So this is not a time for hysterical hyperbole nor any “well-intentioned” covert corporate propaganda, but unprecedented precaution and rational deployment.

    Can indigenous-life destroying yellow cake ever be “green?”

    Yolanda has evoked this dreadful paradox amply, even as Fukishima promises more grave events to come…

    The “good” news? At least Northrop Grumman’s nuclear powered super-carrier USS George Washington has found useful work for a change.

    So why not seize the opportunity to call for this to be a permanent change Mr President! enlighten the Pentagon chain of command, invite them to face the dire reality that nuclear exploitation has wrought, and insist they pledge to demonstrate outstanding leadership, that will transform the trillion dollar doomsday “world-war machine” into a life-affirming engine of enduring health…so long as the boats stay afloat.

    What else can we do but advocate responsible global diversity & proportionate self-determination? when the only other option is to surrender to the dismal inevitability of allowing the dominant forces of death, oppression, blind paranoia and radionuclide decay to dictate our mutual biospheric agenda?

    It’s our choice.
