‘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 . . .
