How then, do we move backwards? How does a society, with most of the people having no clue of future events, move from being dependent on a vast and intertwined network of goods and services produced by the indigenous people of whereever, to a local resource and renewable energy based society, and do so in the timeframe available (20-30 years using the most liberal extimates, 10-20 with resonable estimates, 5-10 with worst case scenarios), all the while prices on everything increasing, world politics getting more militaristic, governments continuously reducing civil liberties, shortages of goods on the market and weather patterns resembling bad Hollywood movies?

Global atmospheric carbon level may depend primarily on southernmost ocean

Circulation in the waters near the Antarctic coast may be one of the planet's critical means of regulating levels of carbon dioxide in the Earth's atmosphere, according to Princeton researchers.
Though climate scientists have long debated the reasons behind the variation in atmospheric levels of carbon dioxide that occur over lengthy periods in Earth's history, the Princeton team may have found a clue to where the answer can be found. In a new research paper, the team reveals that the waters in the Southern Ocean below 60 degrees south latitude, the region that hugs the continent of Antarctica, play a far more significant role than was previously thought in regulating atmospheric carbon, and -- in contrast to past theories -- the waters north of this region do comparably little to regulate it.

CO2 mixdown into the oceans takes centuries so human activity is still going to raise the atmospheric concentration significantly. Too bad this article doesn't deal with the question of how much CO2 uptake in this region will occur in the coming decades. This is not a new process and nothing like an infinite sink so it is the change that is important.

This strikes me as a non-story that doesn't change anything.
Meanwhile, back at the ranch, the CO2 level keeps rising every year. THAT'S what matters. _________________ "Actually, humans died out long ago."
