into the atmosphere had been partially taken up by the ocean; the absorption rate now was about three billion tons of carbon a year into the ocean, and one estimate of the total uptake since the industrial revolution was 400 billion tons. As a result, the ocean had become measurably more acid, going from 8.2 to 8.1 on the pH scale, which was a logarithmic scale, so that the 0.1 shift meant thirty percent more hydrogen atoms in the water. It was felt that certain species of phytoplankton would have their very thin calcium shells in effect eaten away. They would die, a number of species would go extinct, and these very species constituted a big fraction of the bottom of the ocean’s food chain.

      But de-acidifying the ocean was not an option. There were fairly arcane chemistry reasons why it was easier for seawater to become more acidic than to become more basic. A Royal Society paper had calculated, for the sake of estimating the scale of the problem, that if they mined and crushed exposed limestone and marble in the British Isles, ‘features such as the White Cliffs of Dover would be rapidly consumed,’ because it would take sixty square kilometers of limestone mined a hundred meters deep, every year, just to hold the status quo. All at a huge carbon cost for the excavations, of course, exacerbating the very problem they were trying to solve, But this was just a thought experiment anyway. It wouldn’t work; it was an unmitigatable problem.

      And that afternoon, as they went down Diane’s list together, they saw that almost all of the climate and environmental changes they were seeing, or could see coming, were not susceptible to mitigation. Their big success of the fall, the restarting of the thermohaline cycle, had been an anomaly in that sense. The Gulf Stream had rested so closely to a tipping point in its action that humans had, by an application at the largest industrial scale they commanded, managed to tip that balance – at least temporarily. And as a result (maybe) the last month on the East Coast had been markedly warmer than the previous December had been. Perhaps they had even escaped the Youngest Dryas. So now, in one of those quick leaps that humans were prone to make (although science was not), people were talking about the climate problem as if it were something that they could terraform their way out of, or even had solved already!

      It wasn’t true. Most of their remaining problems were so big that they had too much heft and momentum for people to find any way to slow them, much less reverse them.

      So, at the end of this meeting, Edgardo shook his head. ‘Well, this is grim! There is not much we can do! We would need much more energy than we command right now. And it would have to be clean energy at that.’

      Diane agreed. ‘Clean power is our only way out. That means solar power, I’d say. Maybe wind, although it would take an awful lot of pylons. Maybe nuclear, just one last generation to tide us over. Maybe ocean power too, if we could properly tap into currents or tides or waves. To me – when I look at factors like technical developmental readiness, and manufacturing capability, and current costs, and dangers and damage – I’d say our best chance lies in a really hard push on solar. A kind of Manhattan Project devoted to solar power.’

      She raised a finger: ‘And when I say Manhattan Project, I don’t mean the kind of silver bullet that people seem to mean when they say Manhattan Project. I mean the part of the Manhattan Project that not only designed the bomb but also entrained something like twenty percent of America’s industrial capacity to make the fissionable material. About the same percent of capacity as the auto industry, and right when they needed every bit of capacity for the other parts of the war. That’s the kind of commitment we need now. Because if we had good solar power –’

      She made one of her characteristic gestures, one that Frank had become very fond of: an opening of the palm, turned up and held out to the world: ‘We might be able to stabilize the climate. Let’s push all the aspects of this. Let’s organize the case, and take it to Phil Chase, and get him prepped for when he takes office.’

      After the meeting, Frank couldn’t focus. He checked his e-mail, his cell phone, his FOG phone, his office phone: no messages. Caroline had not called for yet another day. No telling where she was or what was happening.

      That night he wandered north up Connecticut Avenue, past the hotel were Reagan had been shot, past the Chinese embassy with its Tibetan and Falun Gong protesters in front singing, until he crossed the big bridge over Rock Creek, guarded by its four Disneyesque lion statues. Out on the middle of the bridge there was a tiny relief from the claustrophobia of the city and forest. It was one of the only places where Rock Creek seemed like a big gorge.

      He continued to the clutch of little restaurants on the far side of the bridge and chose one of the Indian ones. Ate a meal thinking about the names on the wine list. Vineyards in Bangalore, why was this surprising? Read his laptop over milk tea.

      When it was late enough, he struck off to the northwest, toward Bethesda. Back streets, residential, the forest taking over. Night in the city, sound of distant sirens. For the first time in the day he felt awake. It was a long hike.

      Up on Wisconsin he came into the realm of the Persian rug shops, and slowed down. It was still too early. Into a bar, afraid to drink, afraid to think. A whiskey for courage. Out again into the bright night of Wisconsin, then west into the strange tangle of streets backing it. The Metro stop had been like a fountain of money and people and buildings pouring up out of the earth, overwhelming what had been here before. Some of the old houses that still remained undemolished suggested a little urban space of the 1930s, almost like the back streets of Georgetown.

      This was the Quiblers’ neighborhood, but he didn’t want to intrude, nor was he in the mood to be sociable. Too late for that, but not early enough for his task. Pass by and on up Woodson, off to the left, now he was in the well-remembered neighborhood of Caroline and her ex-husband. Finally it was late enough, and yet not too late: midnight. His pulse was beginning to pound a little in his neck, and he wished he hadn’t had that whiskey. The streets were not entirely empty; in this city that wouldn’t happen until more like two. But that was okay. Up the steps of the apartment building that Caroline’s ex had gone into. The drape had pulled back at the top window of the building. He shone his penlight on the address list under its glass, took a photo of it with his cell phone. Quite a few of the little slots had been left blank. He photoed the street address above the door as well, then turned and walked down the street, away from the streetlight he had stood under on that most fateful election night. His own fate, Caroline’s, the nation’s, the world’s – but who knew. Probably it only felt that way. His heart was beating so hard. Fight or flight, sure; but what happened if one could neither fight nor flee?

      He turned a corner and ran.

      Back in his office. Late in the day. He had given Edgardo his information from Bethesda a few days before. Soon he would have to decide again what to do after work.

      Unable to face that, he continued to work. If only he could work all the time he would never have to decide anything.

      He typed up his notes from Diane’s last two meetings. So, he thought as he looked them over, it had come to this: they had fucked up the world so badly that only the rapid invention and deployment of some kind of clean power generation more powerful than what they had now would be enough to extricate them from the mess. If it could be done at all.

      That meant solar, as Diane had concluded. Wind was too diffuse, waves and currents too hard to extract energy from. Fusion was like a mirage on a desert road, always the same distance away. Ordinary nuclear – well, that was a possibility, as Diane had pointed out. A very real possibility. It was dangerous and created waste for the ages, but it might be done. Some kinds of cost-benefit analysis might favor it.

      But it was hard to imagine making it really safe. To do so they would have to become like the French (gasp!), who got ninety percent of their power from nuclear plants, all built to the same stringent standards. Not the likeliest scenario for the rest of the world, but not physically impossible. The U.S. Navy had run a safe nuclear program ever since the 1950s. Frank wrote on his notepad: Is French nuclear power safe? Is U.S. Navy nuclear safe? What does safe mean? Can you recycle spent fuel and guard the bomb-level plutonium that would finally reduce out of it? All that would have to be investigated and discussed. Nothing could be taken off the table just because it might create poisons that would last fifty thousand years.
