Co2 To Ploughshares

800px-Farmer_plowing.jpg An ancient method of ploughing charred plants into the ground to revive soil may also trap greenhouse gases for thousands of years. Here’s how it works: Plants absorb CO2 from the atmosphere as they grow. Burning these plants and trees in airtight conditions produces a high-carbon substance called biochar. Johannes Lehmann of Cornell estimates the carbon storage time of stable biochar could be a few thousand years, reports Reuters.

Lehmann’s ambitious scenario estimates biochar could store 1 billion tons of carbon annually. That’s more than 10 percent of 2007’s 8.5 billion tons of global carbon emissions. His conservative scenario prescribes heating without oxygen (pyrolysis) 27 percent of the world’s crop waste and ploughing it into the soil to store 0.2 billion tons of carbon a year.

According to the International Biochar Initiative, soils with biochar made by Amazon people thousands of years ago still contain up to 70 times more black carbon than surrounding soils and are still higher in nutrients. . . Two big howevers: We can’t cut forests to do this and we can’t avoid reducing CO2 emissions at the same time. But we can put all the little fixes together starting now.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
