We’ve lived so long under the spell of hierarchy—from god-kings to feudal lords to party bosses—that only recently have we awakened to see not only that “regular” citizens have the capacity for self-governance, but that without their engagement our huge global crises cannot be addressed. The changes needed for human society simply to survive, let alone thrive, are so profound that the only way we will move toward them is if we ourselves, regular citizens, feel meaningful ownership of solutions through direct engagement. Our problems are too big, interrelated, and pervasive to yield to directives from on high.

Warming Arctic creates GHG [Green House Gas] danger zone

Click here to access article by Tim Radford from Climate News Network.
Climate scientists have coolly established the mechanism by which a warming Arctic will accelerate the warming of the whole world. It’s simple: as the permafrost warms and dries, it will release ever greater quantities of carbon dioxide from the Arctic soils.

And those bits of tundra that warm, thaw and become increasingly soggy will release ever greater quantities of methane, a greenhouse gas (GHG) more short-lived but also a far more potent heat trap than CO2.
