Last week, after a great deal of debate, the passengers aboard the Titanic voted to impose modest limits sometime soon on the rate at which water is pouring into the doomed ship’s hull. Despite the torrents of self-congratulatory rhetoric currently flooding into the media from the White House and an assortment of groups on the domesticated end of the environmental movement, that’s the sum of what happened at the COP-21 conference in Paris. It’s a spectacle worth observing, and not only for those of us who are connoisseurs of irony; the factors that drove COP-21 to the latest round of nonsolutions are among the most potent forces shoving industrial civilization on its one-way trip to history’s compost bin.

The core issues up for debate at the Paris meeting were the same that have been rehashed endlessly at previous climate conferences. The consequences of continuing to treat the atmosphere as a gaseous sewer for humanity’s pollutants are becoming increasingly hard to ignore, but nearly everything that defines a modern industrial economy as “modern” and “industrial” produces greenhouse gases, and the continued growth of the world’s modern industrial economies remains the keystone of economic policy around the world. The goal pursued by negotiators at this and previous climate conferences, then, is to find some way to do something about anthropogenic global warming that won’t place any kind of restrictions on economic growth.

What that means in practice is that the world’s nations have more or less committed themselves to limit the rate at which the dumping of greenhouse gases will increase over the next fifteen years. I’d encourage those of my readers who think anything important was accomplished at the Paris conference to read that sentence again, and think about what it implies. The agreement that came out of COP-21 doesn’t commit anybody to stop dumping carbon dioxide and other greenhouse gases into the atmosphere, now or at any point in the future. It doesn’t even commit anybody to set a fixed annual output that will not be exceeded. It simply commits the world’s nations to slow down the rate at which they’re increasing their dumping of greenhouse gases. If this doesn’t sound to you like a recipe for saving the world, let’s just say you’re not alone.

It wasn’t exactly encouraging that the immediate aftermath of the COP-21 agreement was a feeding frenzy among those industries most likely to profit from modest cuts in greenhouse gas consumption—yes, those would be the renewable-energy and nuclear industries, with some efforts to get scraps from the table by proponents of “clean coal,” geoengineering, fusion-power research, and a few other subsidy dumpsters of the same sort. Naomi Oreskes, a writer for whom I used to have a certain degree of respect, published a crassly manipulative creed insisting that anybody who questioned the claim that renewable-energy technologies could keep industrial society powered forever was engaged in, ahem, “a new form of climate denialism.” She was more than matched, to be fair, by a chorus of meretricious shills for the nuclear industry, who were just as quick to insist that renewables couldn’t be scaled up fast enough and nuclear power was the only alternative.

The shills in question are quite correct, as it happens, that renewable energy can’t be scaled up fast enough to replace fossil fuels. The little detail they’re evading is that nuclear power can’t be scaled up far enough or fast enough, either. What’s more, however great they look on paper or PowerPoint, neither nuclear power nor grid-scale renewable power are economically viable in the real world. The evidence for this is as simple as it is conclusive: no nation anywhere on the planet has managed either one without vast and continuing government subsidies. Lacking those, neither one makes enough economic sense to be worth building, because neither one can provide the kind of cheap abundant electrical power that makes a modern industrial society possible.

Say this in the kind of company that takes global climate change seriously, of course, and if you aren’t simply shouted down by those present—and of course this is the most common response—you can expect to hear someone say, “Well, something has to do it.” Right there you can see the lethal blindness that pervades nearly all contemporary debates about the future, because it’s simply not true that something has to do it.  No divine providence nor any law of nature guarantees that human beings must have access to as much cheap abundant electricity as they happen to want.

Stated thus baldly, that may seem like common sense, but that sort of sense is far from common these days, even—or especially—among those people who think they’re grappling with the hard realities of the future. Here’s a useful example. One of this blog’s readers—tip of the archdruidical hat to Antroposcen—made an elegant short film that was shown at a climate-themed film festival in Paris while the COP-21 meeting was slouching toward its pointless end. The film is titled A Message from the Past, and as the title suggests, it portrays an incident from a future on the far side of global climate change. I encourage my readers to click through and watch it now; it’s only a few minutes long, and its point will be perfectly clear to any regular reader of this blog. 

The audience at the film festival, though, found it incomprehensible. The nearest they came to making sense of it was to guess that, despite the title, it was about a message from our time that had somehow found its way to the distant past. The thought that the future on the far side of global climate change might have some resemblance to the preindustrial past—that people in that future, in the wake of the immense collective catastrophes our actions are busy creating for them, might wear handmade clothing of primitive cut and find surviving scraps of our technologies baffling relics of a bygone time—seems to have been wholly beyond the grasp of their imaginations.

Two factors make this blindness to an entire spectrum of probable futures astonishing. The first is that not that long ago, plenty of people in the climate change activism scene were talking openly about the possibility that uncontrolled climate change could stomp industrial society with the inevitability of a boot descending on an eggshell. I’m thinking here, among other examples, of the much-repeated claim by James Lovelock a few years back that the likely outcome of global climate change, if nothing was done, was heat so severe that the only human survivors a few centuries from now would be “a few hundred breeding pairs” huddled around the shores of the Arctic Ocean.

It used to be all the rage in climate change literature to go on at length about the ghastly future that would be ours if global temperatures warmed far enough to trigger serious methane releases from northern permafrost, tip one or more of the planet’s remaining ice sheets into rapid collapse, and send sea water rising to drown low-lying regions. Lurid scenarios of civilizational collapse and mass dieoff appeared in book after lavishly marketed book. Of late, though, that entire theme seems to have dropped out of the collective imagination of the activist community, to be replaced by strident claims that everything will be just fine if we ignore the hard lessons of the last thirty years of attempted renewable-energy buildouts and fling every available dollar, euro, yuan, etc. into subsidies for an even more grandiose wave of uneconomical renewable-energy powerplants.

The second factor is even more remarkable, and it’s the existence of that first factor that makes it so. Those methane releases, rising seas, and collapsing ice sheets? They’re no longer confined to the pages of remaindered global warming books. They’re happening in the real world, right now.

Methane releases? Check out the massive craters blown out of Siberian permafrost in the last few years by huge methane burps, or the way the Arctic Ocean fizzes every summer like a freshly poured soda as underwater methane deposits get destabilized by rising temperatures. Methane isn’t the world-wrecking ultrapollutant that a certain class of apocalyptic fantasy likes to imagine, mostly because it doesn’t last long in the atmosphere—the average lifespan of a methane molecule once it seeps out of the permafrost is about ten years—but while it’s there, it traps heat much more effectively than carbon dioxide. The Arctic is already warming far more drastically than any other region of the planet, and the nice thick blanket of methane with which it’s wrapped itself is an important part of the reason why.

Those methane releases make a great example of the sudden stop that overtook discussions of the harsh future ahead of us, once that future started to arrive. Before they began to occur, methane releases played a huge role in climate change literature—Mark Lynas’ colorful and heavily marketed book Six Degrees is only one of many examples. Once the methane releases actually got under way, as I noted in a post here some years ago, most activists abruptly stopped talking about it, and references to methane on the doomward end of the blogosphere started fielding dismissive comments by climate-change mavens insisting that methane doesn’t matter and carbon dioxide is the thing to watch.

Rising seas? You can watch that in action in low-lying coastal regions anywhere in the world, but for a convenient close-up, pay a visit to Miami Beach, Florida. You’ll want to do that quickly, though, while it’s still there. Sea levels off Florida have been rising about an inch a year, and southern Florida, Miami Beach included, is built on porous limestone.  These days, as a result, whenever an unusually high tide combines with a strong onshore wind, salt water comes bubbling up from the storm sewers and seeping right out of the ground, and the streets of Miami Beach end up hubcap-deep in it. Further inland, seawater is infiltrating the aquifer from which southern Florida gets drinking water, and killing plants in low-lying areas near the coast.

The situation in southern Florida gets some press, but I suspect this is because Florida is a red state and the state government’s frantic denial that global warming is happening makes an easy target for humor. The same phenomenon is happening at varying paces elsewhere in the world, as a combination of thermal expansion of warming seawater, runoff from melting glaciers, and a grab-bag of local and regional oceanographic phenomena boosts sea level well above its historic place. Nothing significant is being done about it—to be fair, it’s unlikely that anything significant can be done about it at this point, short of a total moratorium on greenhouse gas generation, and the COP-21 talks made it painfully clear that that’s not going to happen.

Instead, southern Florida faces a fate that’s going to be all too familiar to many millions of people elsewhere in the world over the years ahead. As fresh water runs short and farm and orchard crops die from salt poisoning, mass migration will be the order of the day. Over the short term, southern Florida will gradually turn into salt marsh; look further into the future, and you can see Florida’s ultimate destiny, as a region of shoals, reefs, and islets extending well out into the Gulf of Mexico, with the corroded ruins of skyscrapers rising from the sea here and there as a reminder of the fading past.

Does this sound like science fiction? It’s the inescapable consequence of changes that are already under way. Even if COP-21 had produced an agreement that mattered—say, a binding commitment on the part of all the world’s nations to cut greenhouse gas emissions immediately and lower them to zero by 2030—southern Florida would still be doomed.  The processes that are driving sea levels up can’t turn on a dime; just as it took more than a century of unrestricted atmospheric pollution to begin the flooding of southern Florida, it would take a long time and a great deal of hard work to reverse that, even if the political will was available. As it is, the agreement signed in Paris simply means that the flooding will continue unchecked.

A far more dramatic series of events, meanwhile, is getting under way far north of Florida. Yes, that’s the breakup of the Greenland ice sheet. During the last few summers, as unprecedented warmth gripped the Arctic, rivers of meltwater have begun flowing across Greenland’s glacial surface, plunging into a growing network of chasms and tunnels that riddle the ice sheet like the holes in Swiss cheese. This is new; discussions of Greenland’s ice sheet from as little as five years ago didn’t mention the meltwater rivers at all, much less the hollowing out of the ice. Equally new is the fact that the vast majority of that meltwater isn’t flowing into the ocean—scientists have checked that, using every tool at their disposal up to and including legions of yellow rubber ducks tossed into meltwater streams.

What all this means is that in the decades immediately ahead of us, in all likelihood, we’ll get to see a spectacle no human being has seen since the end of the last ice age: the catastrophic breakup of a major ice sheet. If you got taught in school, as so many American schoolchildren were, that the great glacial sheets of the ice age melted at an imperceptible pace, think again; glaciologists disproved that decades ago. What happens, instead, is a series of sudden collapses that kick the pace of melting into overdrive at unpredictable intervals. What paleoclimatologists call global meltwater pulses—sudden surges of ice and water from collapsing ice sheets—send sea levels soaring by several meters, drowning large tracts of land in an impressively short time.

Ice sheet collapses happen in a variety of ways, and Greenland is very well positioned to enact one of the better documented processes. The vast weight of all that ice pressing down on the crust through the millennia has turned the land beneath the ice into a shallow bowl surrounded by mountains—and that shallow bowl is where all the meltwater is going. Eventually the water will rise high enough to find an outlet to the sea, and when it does, it will begin to flow out—and it will take much of the ice with it.

As that happens, seismographs across the North Atlantic basin will go crazy as Greenland’s ice sheet, tormented beyond endurance by the conflict between gravity and buoyancy, begins to break apart. A first great meltwater surged will vomit anything up to thousands of cubic miles of ice into the ocean. Huge icebergs will drift east and then south on the currents, and release more water as they melt. After that, summer after summer, the process will repeat itself, until some fraction of Greenland’s total ice sheet has been dumped into the ocean. How large a fraction? That’s impossible to know in advance, but all other things being equal, the more greenhouse gases get dumped into the atmosphere, the faster and more complete Greenland’s breakup will be.

Oh, and did I mention that the West Antarctic ice sheet is beginning to break up as well?

The thing to keep in mind here is that the coming global meltwater pulse will have consequences all over the world. Once it happens—and again, the processes that will lead to that event are already well under way, and nothing the world’s industrial nations are willing to do can stop it—it will simply be a matter of time before the statistically inevitable combination of high tides and stormwinds sends sea water flooding into New York City’s subway system and the vast network of underground tunnels that houses much of the city’s infrastructure. Every other coastal city in the world will wait for its own number to come up. No doubt we’ll hear plenty of talk about building vast new flood defenses to keep back the rising waters, but let us please be real; any such project would require years of lead time and almost unimaginable amounts of money, and no nation anywhere in the world is showing the least interest in doing the thing now, when it might still be an option.

There’s a profound irony, in other words, in all the rhetoric from Paris about balancing concerns about the climate with the supposed need for perpetual economic growth. Imagine for a moment just how the coming global meltwater pulse will impact the world economy. Countless trillions of dollars in coastal infrastructure around the world will become “sunk costs” in more than a metaphorical sense; millions of people in low-lying areas such as southern Florida will have to relocate as their homes become uninhabitable, and trillions of dollars of real estate will have its value drop to zero. A galaxy of costs for which nobody is planning will have to be met out of government and business revenue streams that have been hammered by the direct and indirect effects of worldwide coastal flooding.

What’s more, it won’t be a single event, over and done with in a few weeks or months or years.  Every year for decades or centuries to come, more ice and meltwater will go sluicing into the oceans, more coastal cities and regions will face that one seawater surge too many, more costs will have to be met out of what’s left of a global economy that’s running out of functioning deepwater ports among many other things. The result, as I’ve noted in previous posts here, will be the disintegration of everything that counts as business as usual, and the opening phases of the bleak new reality that Frank Landis has sketched out in his harrowing new book Hot Earth Dreams—the best currently available book on what the world will look like in the wake of severe climate change, and thus inevitably ignored by everyone in the current environmental mainstream.

By the time COP-21’s attendees convened in Paris, it was probably already too late to keep global climate change from spinning completely out of control. The embarrassingly feeble agreement that came out of that event, though, has guaranteed that nothing significant will be done. The hard political and economic realities that made any actual cut in greenhouse gas emissions all but unthinkable are just layers of icing on the cake, part of the predicament of our time—a predicament that defines the words “too little, too late” as our basic approach to the future looming up ahead of us.
