Good News From a Drier Amazon

Sometimes things unfold better than we imagine. Apparently drought-stricken regions of the Amazon forest grew particularly vigorously during the 2005 drought, according to new research from the University of Arizona. A prominent global climate model predicted the Amazon forest would “brown down” after just a month of drought and eventually collapse as the drought progressed—one of John Schellnhuber’s scary tipping points.

Detailed, long-term observations from two NASA satellites (one mapping the greenness of vegetation, one measuring rainfall) gave the researchers seven to nine years of observations. They compared “normal” years to the 2005 drought, and found that intact areas of Amazonia that received below-normal rainfall in 2005 had above-average greenness.

Apparently the drought did not accelerate global warming, as feared. In fact, during the 2005 drought, Amazonia’s trees flourished in the sunnier-than-average weather, most likely by tapping water deep in the forest soil. By continuing to grow, they consumed more carbon dioxide, drawing down atmospheric levels, and in theory, at least, producing a negative feedback loop that might have actually slowed global warming.

Lest Limbaugh Rush bolster his feeble argument against climate change, these new data do not undermine the science of global warming. Rather they caution that we can’t afford to substitute opinion for observation. Our planetary systems are hugely complex, our grasp of them fragile, even as Earth struggles to maintain equilibrium. Unlike the naysayers out there, I still see nature as our ally. JULIA WHITTY

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.
