Southern Ocean Nears Acid Tipping Point

Southern_Ocean.png The Australian Broadcasting Corp reports the tipping point for ocean acidification is much closer than first thought. Here’s the problem: As atmospheric CO2 levels rise, the oceans absorb more of it, which cranks their pH to dangerously acidic levels. Beyond a certain tipping point, marine creatures from corals to plankton won’t be able to manufacture the calcium carbonate needed to make their shells.

Until now, the tipping point of acidification was forecast when atmospheric CO2 reached 550 parts per million—around the year 2060. But the new research by Ben McNeil of the U of New South Wales, published in the PNAS, reveals what no one knew before—that carbonate levels drop naturally in the Southern Ocean in winter anyway. Which means the tipping point is likely to be reached at around 450 ppm, which is due to arrive around 2030. Or sooner.

The Nobel-winning IPCC has set 450 ppm as the global stabilization target. However new research shows that number is way too high. Bill McKibben’s excellent piece in the current Mother Jones explains why. BTW, we’re currently at 385 ppm. If we allow ocean acidification to tip, prepare for hellacious repercussions, Earthlings. Jason Grumet, are you listening? Are you briefing the President-Elect? There is no other issue Obama needs to hit the ground running on faster.

AN IMPORTANT UPDATE ON MOTHER JONES' FINANCES

We need to start being more upfront about how hard it is keeping a newsroom like Mother Jones afloat these days.

Because it is, and because we're fresh off finishing a fiscal year, on June 30, that came up a bit short of where we needed to be. And this next one simply has to be a year of growth—particularly for donations from online readers to help counter the brutal economics of journalism right now.

Straight up: We need this pitch, what you're reading right now, to start earning significantly more donations than normal. We need people who care enough about Mother Jones’ journalism to be reading a blurb like this to decide to pitch in and support it if you can right now.

Urgent, for sure. But it's not all doom and gloom!

Because over the challenging last year, and thanks to feedback from readers, we've started to see a better way to go about asking you to support our work: Level-headedly communicating the urgency of hitting our fundraising goals, being transparent about our finances, challenges, and opportunities, and explaining how being funded primarily by donations big and small, from ordinary (and extraordinary!) people like you, is the thing that lets us do the type of journalism you look to Mother Jones for—that is so very much needed right now.

And it's really been resonating with folks! Thankfully. Because corporations, powerful people with deep pockets, and market forces will never sustain the type of journalism Mother Jones exists to do. Only people like you will.

There's more about our finances in "News Never Pays," or "It's Not a Crisis. This Is the New Normal," and we'll have details about the year ahead for you soon. But we already know this: The fundraising for our next deadline, $350,000 by the time September 30 rolls around, has to start now, and it has to be stronger than normal so that we don't fall behind and risk coming up short again.

Please consider pitching in before moving on to whatever it is you're about to do next. We really need to see if we'll be able to raise more with this real estate on a daily basis than we have been, so we're hoping to see a promising start.
