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.

Antarctica’s Southern Ocean May No Longer Help Delay Global Warming

Click here to access article by Jeff Tollefson posted on The Real News Network from an article originally from Scientific American (behind a paywall).
Indirect evidence suggests that the Southern Ocean is a net carbon sink and has absorbed as much as 15% of the carbon emissions emitted by humanity since the industrial revolution. But at some times of year and in specific places in this region, carbon-rich surface waters release CO2 into the atmosphere.

Now, researchers are getting some of their first glimpses in near-real time of what happens in the Southern Ocean, particularly in winter. “Right off the bat, we are seeing CO2 fluxes into the atmosphere that are much greater than we had estimated before,” Sarmiento says. “It’s just revolutionary.”
