CO2 to hit 400 parts per million next month, highest since the Pliocene
April 25, 2013 5:01 PM   Subscribe

Scripps Institute of Oceanography projects that next month its monitoring station will for the first time measure CO2 at 400 parts per million. Atmospheric CO2 has risen from 280 parts per million before the Industrial Revolution. 400 ppm is an arbitrary milestone that we'll blow right past on our way to 450 ppm within a few decades. This is an unprecedentedly fast rate of increase and it's getting faster. Not all measuring stations are exactly the same: A NOAA station in the Arctic measured CO2 at 400 ppm last year.

Just a post to give a nod to the "DANGER" sign as we drive off a cliff.

Huh, I thought 350ppm was our nightmare scenario but we were still years away from that happening? Wasn't that the basis of the Inconvenient Truth movie?

350ppm is considered the upper safe (long term) limit
info here from 350.org

Yes, we are currently in the territory where a catastrophic feedback loop could begin at any moment, if it hasn't already (see record-breaking arctic ice sheet breakup, worldwide reports of record-breaking methane release from permafrost and undersea clathrates, etc).

We are living in a nightmare scenario, it's just that the part where the floor disappears hasn't begun yet, and when it does, we aren't going to wake up before we hit the bottom.

Meanwhile, scientists predict a tenfold increase in frequency of Katrina-size storms if the climate becomes 2C warmer and a 2-fold increase at 0.4C:
"We find that 0.4 degrees Celcius warming of the climate corresponds to a doubling of the frequency of extreme storm surges like the one following Hurricane Katrina. With the global warming we have had during the 20th century, we have already crossed the threshold where more than half of all 'Katrinas' are due to global warming," explains Aslak Grinsted. "If the temperature rises an additional degree, the frequency will increase by 3-4 times and if the global climate becomes two degrees warmer, there will be about 10 times as many extreme storm surges. This means that there will be a 'Katrina' magnitude storm surge every other year."

I have come around to the conclusion that answer to the climate change problem will have to be some form of active solution involving large scale engineering (whether chemical, mechanical, or biological) rather than passive solutions such as reducing emissions. Yes, we must reduce emissions. But we're not going to reduce them far enough fast enough to solve the problem. Pretending we are going to do so is sticking your head in the sand.

To be clear the atmosphere's average concentration is not reaching 400ppm yet -- this is just the first instantaneous reading of 400. It's looking like an average of 400ppm will happen in a couple of years.

I, um. Don't quite know how to react to this. I follow global energy policy and I've seen what the techno-economic models are saying in terms of what choices we're going to make in the coming decades, and I've watched in despair as international climate negotiations collapse again and again. World governments agreed that 450ppm was our target, which would lead to a 2 degree rise, already committing us to cataclysmic climactic disruption, extinctions, sea level rise, extreme weather events, drought, starvation, human suffering. And we utterly utterly failed to reach any kind of political framework that would get us there. We're going to blow past it in a few decades and keep climbing at full speed. Current models have us at +4 or +5 degrees by the end of the century (fully accounting for massive expansion of renewables -- these are predictive models, i.e. what is expected to happen given best available data and forecasts) and at those levels we must talk seriously about the breakdown in global civilization, global ecosystem collapse, and perhaps even human extinction. And we are still building new coal plants.

The reasons why are stark: fossil fuels are plentiful and cheap. Peak oil wasn't wrong, per se -- conventional resources are running out -- but rising price signals unlocked vast unconventional reserves, just as the resource economists predicted. We already know there is more than enough cheaply available fossil fuel to meet demand for the rest of the century. And we also know that, absent some powerful disincentive, the world's people intend to burn those fuels. And we are ramping up renewables, but they're just too expensive and populations do not tend to support things like gasoline taxes. We need a real global carbon price and we need it now, or else we need a Deus Ex Machina technological miracle. And neither of these things seem to be coming.

I try to not to think about the future. I do things that make me happy. I sometimes am able to forget, a little, that this catastrophe is looming, and I let myself daydream about the future, feel optimistic about relationships and experiences waiting for me in the coming decades, imagining myself being happy and growing old the way my parents and grandparents and everyone before did, more or less. And then news like this, it's a punch in the gut, a little reminder that we are the cursed ones who live in interesting times. It takes that optimistic future away from me and I hate it for that. All I see is pain and suffering in the future and I don't want to see that. And I want to end on a high note but I can't. I want it all to be okay. And it won't.

PercussivePaul: The reasons why are stark: fossil fuels are plentiful and cheap.

Don't forget to mention a well-funded fossil fuel/anti-climate science lobby, who claim that even if it is happening and is caused by humans, why hell, there's nothing we can do about it anyway.

Canada's Minister of Energy and Natural Resources Joe Oliver, for example, when he's not in his role as an oil industry lobbyist in Washington, gets his climate science information from Lawrence Solomon in the Financial Post. Mr. Solomon is a well-known climate change denialist. But as long as the FP is making money publishing propaganda against climate science, Lefties and the UN, everything is ok.

In my view, this issue represents the abject failure of modern politics to deal with a real world problem we've known about for over a hundred years. (I still harbour a tiny hope that either the Earth will surprise us, or we'll all pull together to build a low-energy, equitable society that will survive the next 1000 years of climate chaos. It's pretty tiny though.)

To expand on that, there is a lot more land mass (and plant life) in the N. hemisphere. Summertime we turn co2 to plant matter.

Something I don't see discussed much is carbon sequestration via wood construction. I know Dyson reckons we only need a trillion more trees to reduce co2. But why don't we see more calls for wood construction? A mature forest is nearly carbon neutral. A growing forest is a carbon sink. A wood house is a bunch of co2 out of the atmosphere. It didn't occur to me until recently, but it bears repeating. (Virgin forests should remain untouched, of course, but there's a lot of 2nd growth forest.)

There was a technique, back in the olden New Age days, where you would re-breathe your breath into paper bag ever hour or so for several days. The theory was that the larger carbon molecules would stretch your brain vessels, and when you were done with the technique, more oxygen would flow into your brain through the larger tubes.

There was another technique. You swim back and forth across the pool, underwater, holding your breath, as long as you can. The theory was that re-flow would recondition oxygenation through your system, and the larger carbon dioxide molecules moving through your system would increase arterial oxygenation.

Both of these techniques actually work. You can actually become smarter if you do some version of one of these techniques. No shit.

So that's what's happening now. Humanity is holding its breath and re-breathing it. Once we develop energy sources that don't dump a carbon load into the atmosphere, humanity will breathe a collective sigh of relief.

And we will be smarter for it.

The thing that scares me is the thought of how bad things will need to get before the world gets together for what is quite literally a civilization scale project of reducing our emissions, because by the time we can actually continually feel the damage, well-- it's way too late, and no-ones seriously talking about halting our emissions now and beginning to turn them down, only to reducing the rate of growth of them sometime in the nebulous future.

It's going to be problematic for any first world country to say to any developing nation when the time comes, "Hey, I know our people totally raped our land and planet for resources and that allowed us tremendous growth and power, but, well-- can you not do that please, I know there's a pile of coal right there, but.. please don't burn it, okay? Our bad."

The political way I see it happening without mass death is the richer/powerful nations getting together very soon and saying "Look, we're all fucked, we really need to work on skipping every nation, including ourselves over the CO2 hump into the renewable or nuclear energy age, like, now, yes, even China, yes, it's going to be the most expensive undertaking in humanity, and yes, it's probably political suicide." That or persuading your population that they don't actually need cars, air conditioning or beef.

Because the only other hope is science-magic--- that fusion reactors will suddenly start working and we'll just make a load of fusion power silos dotted around the world who just spend their days breaking the C out of CO2, turn it into diamond and build huge mountains of the stuff, and we'll put a big ol' sun-shade up in space for good measure too.

And sadly, my only real hope is in the latter.

Thinking about it from a political point of view, global warming is a very difficult problem because the atmosphere is a globally shared resource, but we don't have a global government. (And we're not likely to ever have one, no matter how bad things get. Based on our past experience with would-be conquerors, I think we can say that attempting to create a single world government would result in killing an unimaginable number of people, and also fail.)

That said, it's possible for independent states to negotiate agreements over shared resources. The rational way to deal with the problem would be to put a gradually rising carbon tax into place (William Nordhaus provides an overview). The two key actors here are the US and Chinese governments; Europe is already on board. I don't know about China (according to the Economist, China's planning a cap-and-trade system), but in the US, action will be very difficult, because 37% of US voters believe that global warming is a hoax. The most promising route would be EPA regulation.

If you're looking for something you can do, putting pressure on the Obama administration to act would be a good idea. Amy Goodman and Denis Moynihan:
[Obama] answered with a story about the legendary 20th-century organizer A. Philip Randolph meeting with President Franklin Delano Roosevelt. Randolph described to FDR the condition of black people in America, the condition of working people. Reportedly, FDR listened intently, then replied: “I agree with everything you have said. Now, make me do it.” That was the message Obama repeated.
Of course, as historians know, people (in general) and leaders (in particular) don't always do the rational thing. (Barbara Tuchman wrote an entire book on this subject, The March of Folly.) If I had to make an estimate, I'd say there's maybe a 30% chance that we'll see a diplomatic solution (based on the three elements of diplomacy: persuasion, compromise, and threats) which keeps CO2 at a less-than-all-out-catastrophe level.

A fallback would be a technical solution: geo-engineering.

And if that doesn't work out? Then I think what will happen will be the less-rational way of resolving conflicts: namely, violence.

Economics is good for studying everyday life: a market of buyers and sellers, with prices determined by supply and demand. If demand increases a bit, or supply decreases a bit, prices rise a bit. A free market results in maximum efficiency.

But when there's sudden catastrophic changes in the supply of food, with no substitutes available? People aren't going to quietly starve to death when they can't afford to buy food. What happens next isn't in the domain of economics. It's the domain of power politics and war. People will overthrow their governments. They'll fight over what's left.

I had the most depressing conversation with my father recently. My dad has always been sort of a climate optimist - "oh, global warming is happening, but I lived through predictions of Soylent-Green style overpopulation and followed by predictions of nuclear winter, so I tend not to believe in apocalyptic scenarios, plus there must be some kind of planetary homeostasis effect or we will figure out the technology" - but when we last talked, he said he felt like global warming was unstoppable and going to be a huge, huge disaster. This is, of course, what I've thought since about 1992, but hearing it from my dad was a bit of a shock, since I still tend to assume semi-consciously that Dad Is Right and I'd always kind of relied on some kind of "ha ha Frowner is so negative, we beat global warming in 2015 with this convenient cheap method" scenario.

So anyway, we went on to basically agree that I was reasonable not to want kids. They've long since accepted that there won't be any grandchildren, but I know they've always kind of wanted some and it was a bit scary to realize that my dad the climate optimist had switched over into "just as well that Frowner isn't having any kids really".

Then we shared our respective worries - him for my generation (although honestly I am rising forty and although I'd like to live another thirty, thirty-five years, I've at least had a decent time) mine for my friends' young kids. I mean, I have friends whose kids are two. They may not even be that old when we're at 4 degrees and high-tech human global civilization is firmly impossible.

Justinian: "I have come around to the conclusion that answer to the climate change problem will have to be some form of active solution involving large scale engineering (whether chemical, mechanical, or biological) rather than passive solutions such as reducing emissions. Yes, we must reduce emissions. But we're not going to reduce them far enough fast enough to solve the problem. Pretending we are going to do so is sticking your head in the sand.

Let's get DARPA started on solar mirrors or something.
"

I've been saying the same thing for years now. (To the bathroom mirror and in threads like this one.) The time when emissions reduction alone might have worked was the early 90s, after the Soviet Union fell and Chinese industrialization was just getting started. That time was like the chapter break in a history book, but we're living in 2013 now and this era is well and truly in progress. Billions of people are in the process of lifting themselves into a better way of life and no treaty to reduce emissions will ever be enforced until that process is done, or disaster intervenes.

This is a technological problem now, and the big question is how bad things have to get before we seriously start looking to solutions. It can be fixed, or mitigated, but we should be spending billions of dollars studying this, in every nation. Fighting battles over things like the Keystone pipeline is almost a form of denialism itself at this point, by people pretending that emissions reduction will happen in time.

Carbon capture is the future. If we can get CO2 out of the atmosphere, we stand a good chance at stopping, even reversing these really terrifying trends.

We have to do carbon capture. Along with cutting emissions, sure, but...what if what if what if...

What if we develop cc technology to the point that we can take out of the air more than is being put in? (Even if it's more than what we output now; renewables notwithstanding, it will be.) That might not be enough to solve the warming problem, but then again it might be. In all our lifetimes to boot.

I think it's worth pointing out that the presumption that the right "disbelieves" in climate change is certainly incorrect. The smart people on the right trust science as much as the left does. They know the CO2 levels are rising and the world is going to warm and change dramatically and dangerously in the next century.

The key truth is that they don't care. Why? Because they have the money to survive it, and they don't give a shit about the people who don't. (Have you heard this song before? It's the song of the libertarian a.k.a. the song of the blessed/entitled. There is no free lunch; if you can't pay for something, you can't have it. That includes fresh air and a planet that was more or less as habitable as we found it. Never mind that they're the ones driving up the price.)

So why all the noise in the media about how false climate change is? Because they have to quell the revolution that would happen if Joe Six Pack and Jane Apple Pie in Flyover, NB started to pay attention to the science. That's why science is repressed. That's why authoritarianism and religious beliefs are encouraged. Because that's how you keep the people quiet: you lie. Lie so loudly and so often that there is no headspace for a challenging thought much less and opposing point of view.

And then it's too late, and then the lies will change about who was responsible. And the oil-igachists will have plenty of money to live in comfort in the newly temperate Siberia and Nunavut, and so the world will continue as it should, with maybe 250 million people, most of them subsistence farmers on the high plains near the (former) Arctic Circle, and a couple million in scattered walled fortresses, which will eventually fall into warring fiefdoms over rare earths.

But they're going to live on a private island? Yes? And who will be picking the Tomatos and slaughtering the swine for their BLTs in this post-apocolyptic beach resort?

A thriving, functioning, stable economy for the masses is what gives their obscene wealth value. If they think they have what it takes to be an Eritrean warlord, bully for them. But I think that's not quite the comfortable retirement that most have in mind.

This is indeed depressing as all hell.

I'm not sure which of the two is less feasible.

My deepest hope for a "magic bullet" is new battery technology. There is a trillion dollars on the table at a minimum for anyone who can develop a fast-charge battery with even just 5x the capacity/density of current lithium products at a comparable price. That would turn an electric car from a joke/toy at a 200 mile range to an amazing product with a 1000 mile range. And imagine if they had a 10 or 20x battery. Yes you need to put electricity in it, but all of our best renewable technologies these days generate electricity, not carbons.

I keep hearing about new 10x batteries just a couple years away now. I am hoping. So much hope. Hope hope hope.

Asia Times: World enters a resource-shock era
Essentially, climate change will wreak its havoc on us by constraining our access to the basics of life: vital resources that include food, water, land, and energy. This will be devastating to human life, even as it significantly increases the danger of resource conflicts of all sorts erupting.

We already know enough about the future effects of climate change to predict the following with reasonable confidence:
Rising sea levels will in the next half-century erase many coastal areas, destroying large cities, critical infrastructure (including roads, railroads, ports, airports, pipelines, refineries, and power plants), and prime agricultural land;
Diminished rainfall and prolonged droughts will turn once-verdant croplands into dust bowls, reducing food output and turning millions into "climate refugees".
More severe storms and intense heat waves will kill crops, trigger forest fires, cause floods, and destroy critical infrastructure

I can't help but think if the US had weened itself off Arab oil we would have bankrupted "those who hate freedom" and set an economic example to the rest of the world.

We can blame Ronald Reagan for putting the U.S. mindset 30 years behind. Back in the late 70s solar was in its infancy but people were really serious about it. We should've started then with the solar race; the U.S. would now be on top in the solar industry, not Germany and China.

Jimmy Carter put solar panels on the White House. Reagan came in in 1980 and took them down. That one action set back solar for decades, at least in the U.S. It actually made people anti-solar.

LOL wut? How the fucking hell does my misanthropy make me anywhere NEAR Ayn Rand levels. Look - if we actually succeed in turning shit around, then fine, but there is nothing that says we deserve to have a goddamned planet, let alone inherit the universe in some sense of hubristic self-righteousness if we don't manage to not fuck up the one we live on in the first place. I'd argue that it's up to us as a species to prove ourselves to do the right thing. Ayn Rand doesn't give two fucking shits about anyone else but Ayn Rand (and the same goes for her fucking acolytes).

My point is that we, AS A COLLECTIVE SPECIES, better do something but so far we haven't proven ourselves capable, and there is a feedback system in effect that you can't argue against. You put CO2 in, the temperature rises. This is a scientific fact (simplified, of course), but to act as if hey - let's build a spaceship since we fucked up this first one, without showing that we've gained any wisdom to not do the same in the future doesn't bode well for a space faring species...

My point was that I used to be a transhumanist and though hey let's all upload our brain into computers yada yada, and I'm so far away from that now. In fact, the dominant political philosophy in transhumanism would be egoist individualism (that's not the only one, of course, but it definitely does have a dominant position -- or at least did in the 90s when I was considering myself as one). I've moved into Communism. Explain how I'm "one trashy novel away from ...?"

I don't understand what's so hard to say that these are very natural and real forces that have an actual effect on feedback cycles in complex systems, and because I deign to say that we caused this effect ourselves, we'll end up suffering the consequences if we don't change our act, and that we don't particularly deserve to inherit the universe if we don't act to reverse this process, I'm on par with Egoist Ayn Rand?

Frowner: So anyway, we went on to basically agree that I was reasonable not to want kids.

The future is inherently uncertain. Yes, it's possible that things will be terrible. But we don't know that for certain.

I'd say that there's a good chance of famine and war in the medium-term future (say 50 years). But it's not like history isn't full of famine and war.

Looking back only 100 years, large parts of the world went through terrible times during the 20th century. Thinking of China, for example, there was civil disorder, followed by revolution; warlords; the Japanese invasion; civil war; the Korean War; the Great Leap Forward, during which 15-30 million people starved; the Cultural Revolution. And the 20th century isn't even the worst. The German states lost 25-40% of their population during the Thirty Years' War. France lost half its population during the Hundred Years' War.

Of course we should do everything in our power to prevent catastrophe. But we also shouldn't assume that if we're unsuccessful, the world will literally end. It'll just be a much poorer, hungrier, and more violent place.

Jonathan Chait: Why Obama Might Actually Be the Environmental President.

Chait discusses Obama's record so far:
What has he done? He has done quite a bit, probably far more than you think, and not all of it advertised as climate legislation, or advertised as much of anything at all. The American Recovery and Reinvestment Act was many things—primarily, a desperate bid to shove money into enough Americans’ pockets to prevent another Great Depression—but one of them was a major piece of environmental reform. The law contained upwards of $90 billion in subsidies for green energy, which had a catalyzing effect on burgeoning industries. American wind-power generation has doubled, and solar power has increased more than six times over....

The stimulus had the misfortune of absorbing the brunt of the public’s dismay with the economic crisis, and Republicans successfully turned Solyndra, an anomalous case of a green-energy subsidy that went bust, into a symbol that rendered the whole law so unpopular Democrats quickly grew afraid to tout it. Even a close observer like [Nicholas] Lemann has forgotten that it was indeed “major environmental legislation.” And yet, the wave of innovation—new fuels, plus turbines, energy meters, and other futuristic devices—will reverberate for years. Envia Systems, a stimulus-financed clean-energy firm in Silicon Valley, has developed technology for electric-car batteries three times as efficient as the technology in the Volt, capable of shaving $5,000 off the sticker price of an electric car when it comes to market in 2015. Just a few weeks ago, the Times reported on a new stimulus-financed research project to increase the energy content (and thus reduce the emissions) of natural gas.

The administration has also carried out an ambitious program of regulation, having imposed or announced higher standards for gas mileage in cars, fuel cleanliness, energy efficiency in appliances, and emissions from new power plants. In aggregate, they amount to a major assault on climate change. Some environmentalists judge them to be insufficient—a fair critique—but many more Obama supporters aren’t even aware that they exist. This is likely because none of these regulations produced any political theater. There was no legislation, no ponderous Sunday-morning talk-show chin-scratching, no dramatic wrangling of votes on the House floor. Just the issuing of a new regulation, a smallish one-day story.
More speculatively, Chait thinks that the Obama administration will regulate emissions from existing coal-fired power plants:
So far, there is one hole in his regulatory agenda: power plants that currently exist. This is, unfortunately, a very large hole, as these plants, mostly coal, emit 40 percent of all U.S. carbon emissions.

... a few weeks after last year’s election, the Natural Resources Defense Council published a plan for the EPA to regulate existing power plants in a way that was neither ineffectual nor draconian. The proposal would set state-by-state limits on emissions. It sounds simple, but this was a conceptual breakthrough. Much like a cap-and-trade bill, it would allow market signals to indicate the most efficient ways for states to hit their targets—instead of shutting coal plants down, some utilities might pay consumers to weatherize their homes, while others might switch some of their generators over to cleaner fuels. The flexibility of the scheme would, in turn, reduce the costs passed on to consumers. Here is a way for Obama to use his powers—his own powers, unencumbered by the morass of a dysfunctional Congress—in such a way that is neither as ineffectual as a firecracker nor as devastating as a nuke: The NRDC calculates its plan would reduce our reliance on coal by about a quarter and national carbon emissions by 10 percent.

... New regulations would have to withstand a certain legal challenge from the energy industry—though, crucially, implementation would not have to wait as cases wind their way through the courts. The EPA’s authority has withstood several high-profile challenges before, because the law is so broadly written; on the other hand, the challenges to Obamacare remind us that precedent cannot fully predict the behavior of agitated conservative judges. Also like the Obamacare challenge, the legal fight will play out against the backdrop of political war. Republicans in Congress have proposed barring the EPA from using its powers—in Senator James Inhofe’s formulation, “Put Congress, not unaccountable bureaucrats, in charge of deciding the nation’s energy policy.” The Wall Street Journal editorial page has described Obama’s threat to regulate carbon emissions as something akin to the action of a “dictator.”

So the administration and its allies have been mobilizing for combat....

[Dan] Lashof predicted the following sequence of events. The agency will finish drafting its regulation scheme by the end of the year. It will then take about a year of public comments and revisions, at which point it will finalize its rule. That will be the end of 2014, just after the midterm elections.
Chait suggests that this timeline would give Congress a chance to pass its own climate legislation (even though it won't).
