Reactions To The Phytoplankton Crisis

As I was preparing my post How We Wrecked The Oceans—Part II, I ran across several reactions from scientifically illiterate but politically savvy bloggers. I want to go through some of what they said. I am not here to praise them.

Several readers picked up on my remarks that the catastrophic result—we have lost 40% of the phytoplankton in the oceans since 1950—seems unlikely because surely we would be feeling the effects of such a disaster now. The Earth's major processes (it's primary productivity, the carbon cycle) don't change overnight—there is a lot of inertia in these systems. A major shift may take decades or even centuries to play out, even given the very rapid changes (in Geological Time) humankind has set in motion. Right now, our best knowledge says we have lost phytoplankton in the oceans at a rate of 1%/year since 1899. Until some new research casts doubt on that result, we must provisionally assume it is accurate.

Writing at The Atlantic, business & economics editor Megan McArdle gave us her views in The Phytoplankton Panic. She quotes and reacts to political blogger Kevin Drum's Phytoplankton Dammerung—

Kevin Drum brings the gloom:

So, anyway, as temperatures rise the plankton die. As plankton die, they suck up less carbon dioxide, thus warming the earth further. Which causes more plankton to die. Rinse and repeat. Oh, and along the way, all the fish die too.

Or maybe not. But this sure seems like a risk that we should all be taking a whole lot more seriously than we are. Unfortunately, conservatives are busy pretending that misbehavior at East Anglia means that global warming is a hoax, the Chinese are too busy catching up with the Americans to take any of this seriously, and you and I are convinced that we can't possibly afford a C-note increase in our electric bills as the price of taking action.

As a result, maybe the oceans will die. Sorry about that, kids, but fixing it would have cost 2% of GDP and we decided you'd rather have that than have an ocean. You can thank us later.

I actually think that Kevin misses the point a little:  if this is true, 2% of GDP isn't going to cut it.  We'd better get back to an emissions level around 1940, or earlier, and stay there.  Being that we now have about 2.5 times as many people in the country, and the world, as we did then, that's going to be tricky.  If higher emissions means the trend will continue, we're pretty much doomed...

Drum, writing at Mother Jones, immediately makes the phytoplankton result a political issue. Liberal Democrats ("the Good Guys") can fix this problem at minimal cost but Conservative Republicans ("the Bad Guys") won't let them. Here's what the Congressional Budget Office said about Waxman-Markey, the House version of the CO₂ cap & trade bill to which Drum is referring—

Reducing the risk of climate change would come at some cost to the economy. For example, the Congressional Budget Office (CBO) concludes that the cap-and-trade provisions of H.R. 2454 [Waxman-Markey], the American Clean Energy and Security Act of 2009 (ACESA), if implemented, would reduce gross domestic product (GDP) below what it would otherwise have been—by roughly ¼ percent to ¾ percent in 2020 and by between 1 percent and 3½ percent in 2050. By way of comparison, CBO projects that real (inflation-adjusted) GDP will be roughly two and a half times as large in 2050 as it is today, so those changes would be comparatively modest. In the models that CBO reviewed, the long-run cost to households would be smaller than the changes in GDP...

I assume Drum's 2% of GDP cost estimation for fixing global warming is roughly the midpoint of between 1 and 3½ percent in GDP in 2050.

This is the proverbial Free Lunch, which as we should all know by now, does not exist. Extraordinarily optimistic assumptions have been made about the growth in and the efficacy of carbon-free energy technology, and about future economic growth, where GDP is assumed to be roughly two and a half times as large in 2050 as it is now. When assessed against all this future growth, the cost of mitigating global warming is basically nothing, as Drum assumes. This is pure fantasy. And what of McArdle's bold assertion that we need to get back to 1940 CO₂ emissions levels and stay there?

Here is the graph from the International Energy Agency showing what needs to be done to stabilize CO₂ in the atmosphere at 450 ppm (parts-per-million). It is taken from my long, technical article Economic Growth And Climate Change — No Way Out?

Source: IEA's 2009 World Energy Outlook. As the IEA's caption notes, global economic growth (in real terms) is assumed to be 2.7% per year after 2030.

Look at the curve, study the graph. Does that look doable to you? To fix anthropogenic climate change, we must return to pre-1940 levels of CO₂ in the atmosphere and maintain those levels indefinitely as the human economy grows exponentially out to 2150. Can we achieve this? Of course not—these kind of scenarios are delusional!

But through the lens of politics & business-as-usual, not only can we achieve 450 ppm, but it will only cost roughly ¼ percent to ¾ percent of GDP in 2020 and by between 1 percent and 3½ percent of GDP in 2050. Paul Krugman's Who cooked the planet? makes precisely the same brain dead point Kevin Drum does about Good Guys versus Bad Guys (and those evil Chinese). Such is the level of political discourse in the United States.

Am I right to say that politics makes you stupid as I first wrote in All We Have Is Each Other? Perhaps it's a chicken & egg problem—which comes first? The politics? Or the stupidity?

Returning to our intrepid bloggers, Drum notes that the BBC made sure to include a sanitized version of the phytoplankton catastrophe—

If the planet continues to warm in line with projections of computer models of climate, the overall decline in phytoplankton might be expected to continue. But, said, Daniel Boyce, that was not certain. "It's tempting to say there will be further declines, but on the other hand there could be other drivers of change, so I don't think that saying 'temperature rise brings a phytoplankton decline' is the end of the picture," he said.

Boyce is waiting around for something magical to happen which will reverse the phytoplankton decline. The Atlantic blogger McArdle picks up on this theme in the third of her attempts to rescue the situation—

1.  It's one paper.  I am not casting aspersions on the authors or their methodology, but the whole idea of science is that even the smartest people can be wrong.  As with other attempts to reconstruct past climate, they're using a series of proxies for past events that have much weaker accuracy than the direct measurements we're now using.  That doesn't mean they're wrong, but it does leave them more open to interpretation.

2.  All the carbon we're burning used to be in the atmosphere.  Yet the planet supported life.  Indeed, the oil we're burning comes from the compressed, decayed bodies of . . . phytoplankton.  This suggests that some number of phytoplankton should be able to survive high concentrations of the stuff.

3.  There are positive feedback effects, but also negative ones.  One of the things that drives me batty about environmentalists and journalists writing about climate change is the insistence that every single side effect will be negative. This is not really very likely, unless you think that every place on earth just happens to be at the very awesomest climate equilibrium possible as of 9:17 am this morning, or that global warming is some sort of malevolent god capable only of destruction. 

Mind you, this is not an argument for letting it happen...

I agree with her first point. (How could I not?) Her second point says all the carbon we're burning used to be in the atmosphere. Well, yes, it was in the atmosphere at some point, but not all at the same time! (The last time CO₂ levels were at current levels is thought to have been the early Miocene Epoch about 22 million years ago.) Apparently, Megan is unfamiliar with the Earth's Carbon Cycle.

As to the third point, the climate was in a (more or less) stable equilibrium throughout the last interglacial period (the Holocene Epoch, roughly the last 12,000 years) until we humans disturbed that equilibrium. There is little reason to expect some Gaia-like thermostat to kick in which will preserve the former stability when we consider the massive, unnatural pressure we have exerted on Earth's natural systems. This is just wishful thinking, but who knows? Maybe we'll get lucky!

It is not my intention to depress you today by pointing out the likely impossibility of fixing this phytoplankton crisis, especially if we've truly got an unreversible trend on our hands. But there is no excuse for whitewashing the problem, and there is no excuse for scientific illiteracy when that's what we need more of in public policy discussions. I have little faith in the ability of Homo sapiens to fix the problems our species has created, and the mindless remarks of people like McArdle, Drum and Krugman only reinforce that belief.

Every problem we face from environmental to economic can be traced to one cause that nobody seems to want to touch.

OVERPOPULATION

It's like the third rail in our society and around the world.The earth has a certain amount of humans it can handle and when you go over it it's the same as when the population of deer in a given area
exceed it's ability to sustain them. Starvation.

The thing is,humans like to think were so smart,but they can't come to grips with such a basic concept.

Why is that?

[Jb]

Yep, unfortunately I have to agree: it ain't gonna happen voluntarily. Like Chris in Chicago, all I can see in the chart above is war and mass starvation. Once that happens, we'll achieve equalibrium all right. Who knows, maybe it will be in time to save the fish.

I've been in the 'sustainability' business for over 10 years now and I can assure you that NONE of my clients have ever been willing to modify their behavioral patterns because it was 'the right thing to do.' We had to use 'return on investment' to sell the green revolution and gave them third party verification systems so they could brag about it, but in the end, it won't do much good.

As JM Greer once wrote to a commentor on his blog: 'hope you like camping.'

[Edward Boyle]

I just hate hearing about the environment.It makes me feel so totally helpless. All that methane stuff and now this. PO I can accept. So what about a massive die off due to lack of fuels but like extinction of all life and like totally inevitable really sucks. This sounds like the meteorite in Armageddon/Deep Impact. Everybody stick your head between your legs and kiss your a** goodbye. I pray for a miracle and then go buy an end time bomb from Dr. Strangelove to speed it all up and to save something for the cockroaches in the hope at least they will evolve back to intelligent life.

As Oppenheimer thought upon seeing the bomb tested:

"...now I am become Death [Shiva], the destroyer of worlds..."

Exact quote from Bhagavad Gita:

Quote

If the radiance of a thousand suns
Were to burst at once into the sky
That would be like the splendor of the Mighty one...
I am become Death,
The shatterer of Worlds.

Unquote

This should be the level of the awe we are feeling about all this but we just muddle through unable to do anything and it just gets worse every day. This discovery is certainly on a par or worse than the discovery that CFCs were destroying the ozone layer which would also bring about a quick end to life on earth. Industrial life seems to be the culprit. Humanity itself is not evil. I only hope there is a God and that he means well by us. I just can't take all this guilt on me. The burden is too much to bear. This is
the obvious root of the denial noted by the noted bloggers.

[Chris in Chicago]

I have seen the same thing as you mention JB about sustainability. I am a residential rehabber and have read,watched,heard and talked to manufacturers who are all pushing green products and energy efficiency,but i see no interest in it at the residential level outher than a few wealthy people who are concerned about the environment and don't care about how much they spend and wont get back.

Realisticly though,if you are just getting by,you can't expect the average person to throw tens of thousands of dollars into there home to make it energy efficient that they are not going to recoup.

[Robert H]

There is a more immediate and stunning, perhaps terrifying, concern about the destruction of the ocean's phytoplankton. Close to half of the Earth's atmospheric oxygen is produced by phytoplankton. How long can you hold your breath?

[Guy Archer]

Paul Krugman wrote: "If you want to understand opposition to climate action, follow the money. The economy as a whole wouldn’t be significantly hurt if we put a price on carbon, but certain industries — above all, the coal and oil industries — would. And those industries have mounted a huge disinformation campaign to protect their bottom lines." Do you disagree? The U. S. tax code has for many years promoted business and industry with a variety of tax dodges. Now we urgently need tax incentives to save the planet!

[Adamatari]

This is what I think:

Anyone (like the economist/magical thinker McArdle) who doesn't realize that if true it means DOOM, capital letters, serious problems staying alive DOOM, is utterly ignorant that we live on an ocean planet, and is ignorant about basic biology and ecology. A decline of 40% of phytoplankton will noticeably affect the ability of humans to survive on this planet.

I think more research is needed right now, and we need to see if other people back up this result. To me, so far this study is bringing more questions than answers. If true, disaster. But I'm not going to accept one paper as absolute proof. That's not scientific illiteracy; that's a recognition that science requires confirmation.

Still, even if it's not nearly as bad, we need to change our approach to the oceans drastically, and yesterday. This is not a joke, or just another piece of bad news. This is the bell tolling.

[Jonny Mnemonic]

Hate to be a doomsday guy, but I don't see us fixing this. We lost 40% of the phytoplankton in the last 60 years. But the trend is accelerating, so I'm guessing 40 years left before the other 60% are gone. Long before that we will see the food chain breaking down. In fact, we probably already are - that would explain the waves of large numbers of sea mammals washing ashore dead of starvation. That's a sign that the food chain is compromised and deteriorating rapidly, top to bottom. Human civilization may not have longer than 2 or 3 decades left, and that's nowhere near long enough to address this problem in time to make a difference. Game over, man. Prepare yourselves for rioting, a breakdown in law and order, loss of services and utilities, anarchy, starvation and cannibalism. Got kids? That's their future. Younger than 40? That's probably YOUR future too. On the plus side, we won't need to worry much about Social Security or Medicare running out - the human race is going to run out first.

[Bustin J]

Yes, the only solution is the hardest. You've got to rein in the fishermen. You've got to say, Global Warming is upon us, and your occupation is the first to go. Then you have to popularize living like its the 1940s. I would suggest sitting Justin Beiber down and having a serious talk. Likewise with Hollywood.

I think we'll have to force this change popularly. That means blocking roads with overturned cars- our own cars- and having a mini-Tahir square event outside every state capitol building.

I think the best we can hope for is a new priority for the US, its military used to unilaterally enforce an ecological set of laws. Global communism is another possibility.

Fantastical ideas. Change impossible without a mass global movement, a massive sea change in basic value systems.
