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. - Green World Rising, Published on Sep 19, 2014
