Old DDT Migrating North

Here’s the trouble with emissions. They’ve got killer hangovers. Take DDT. Not only is it still with us, it’s actually increasing in the western North Atlantic—despite 30 years of restrictions on its use.

A modelling study published in Geophysical Research Letters finds substantial quantities of the pesticide still being released from the World Ocean. And though most DDT use today occurs in the southern hemisphere, concentrations are growing in the northern hemisphere as the old stuff cycles between oceans and atmosphere.

In fact, this study’s computer model, simulating DDT circulation between ocean and atmosphere from 1950 to 2002, suggests the regurgitation of old DDT from the ocean is now greater than from ongoing sources of DDT.

Plus the stuff’s migrating north and has been since the 1960s. Says the paper:

“The sea region that has been representing the most significant (secondary) DDT source is the western N Atlantic (Gulf stream and N Atlantic Drift regions).”

More bad news for a heavily populated part of the world and all the marine life left in those once heavily populated waters.
 

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.
