Industrial Civilization has Potential to Trigger Mass Extinction

2013 arctic methane releases

The 10 minute film "Last Hours" is designed to awaken people to the fact that industrial civilization with its production of greenhouse gases has the ability to trigger a mass extinction which could threaten not just human civilization, but the very existence of human life on this planet.

Burning fossil fuels releases carbon that heats the atmosphere and the seas through the greenhouse gas effect. This is happening most rapidly at the polar extremes.  Methane is already being released from deposits beneath melting arctic ice, from the warming northern-hemisphere tundra, and from worldwide continental-shelf undersea methane frozen in water called methane hydrate.

If we fail to significantly reduce the use of carbon-based fossil fuels, this freed methane threatens to greatly increase the speed of global warming, potentially producing a disaster beyond the ability of the human species to adapt.
