But sunlight itself rained down perpetually. About seventy percent of the photosynthesis that took place on Earth was already entrained to human uses, but photosynthesis only caught a small fraction of the total amount of solar energy striking the planet each day. Those totals, day after day, soon dwarfed even what had been caught in the Triassic fossil carbon. Every couple of months, the whole Triassic’s capture was surpassed. So the potential was there.
This was true in so many areas. The potential was there, but time was required to realize the potential, and now it was beginning to seem like they did not have much time. Speed was crucial. This was the reason Diane and others were still contemplating nuclear.
It would be good if they needed less energy. Well, but this was an entirely different problem, dragging in many other issues – technology, consumption, lifestyles, values, habits – also the sheer number of humans on the planet. Perhaps seven billion was too many, perhaps six billion was too many. It was possible that three billion was too many. Their six billion could be a kind of oil bubble.
Edgardo was not calling, neither was Caroline calling.
Desperate for ways to occupy his mind – though of course he did not think of it that way, in order not to break the spell – Frank began to look into estimates of the Earth’s maximum human carrying capacity. This turned out (usefully enough for his real purpose) to be an incredibly vexed topic, argued over for centuries already, with no clear answers yet found. The literature contained estimates for the Earth’s human carrying capacity ranging from one hundred million to twelve trillion. Quite a spread! Although here the outliers were clearly the result of some heavily ideological analysis; the high estimate appeared to be translating the sunlight hitting the Earth directly into human calories, with no other factors included; the low estimate appeared not to like human beings, even to regard them as some kind of parasite.
The majority of serious opinion came in between two billion and thirty billion; this was satisfyingly tighter than the seven magnitudes separating the outlier estimates, but for practical purposes still a big variance, especially considering how important the real number was. If the carrying capacity of the planet were two billion, they had badly overshot and were in serious trouble, looking at a major die-back that might spiral to near extinction. If on the other hand the thirty billion figure was correct, they had some wiggle-room to maneuver.
But there were hardly any scientific or governmental organizations even looking at this issue. Zero Population Growth was one of the smallest advocacy groups in Washington, which was saying a lot; and Negative Population Growth (a bad name, it seemed to Frank) turned out to be a mom-and-pop operation run out of a garage. It was bizarre.
He read one paper, written as if by a Martian, that suggested if humanity cared to share the planet with the other species, especially the mammals – and could they really survive without them? – then they should restrict their population to something like two billion, occupying only a networked fraction of the landscape. Leaving the rest of the animals in possession of a larger networked fraction. It was a pretty persuasive paper.
As another occupier of his thoughts (though now hunger was going to drive him out into the world), he looked into theories of long-term strategic policy, thinking this might give him some tools for thinking through these things. It was another area that seemed on the face of it to be important, yet was under-studied as far as Frank could tell. Most theorists in the field, he found, had agreed that the goal or method of long-term strategic thinking ought to be ‘robustness,’ which meant that you had to find things to do that would almost certainly do some good, no matter which particular future came to pass. Nice work if you could get it! Although some of the theorists actually had developed rubrics to evaluate the robustness of proposed policies. That could be useful. But when it came to generating the policies, things got more vague.
Just do the obvious things, Vanderwal. Do the necessary.
Diane was already acting in the manner suggested by most long-term strategy theory, because in any scenario conceivable, copious amounts of clean solar energy would almost certainly be a good thing. It was, therefore, a robust plan.
So, solar power:
1) there were the photovoltaics, in which sunlight was transformed into alternating current by way of photons stimulating piezoelectricity in silicon.
2) There were the Stirling engines, external heat engines that used mirror dishes controlled by computers to reflect sunlight onto a hydrogen-filled closed element that heated to 1,300 degrees Fahrenheit, driving pistons which generated the electricity. The engine had been designed by a Scot named Stirling in 1816.
All solar technologies had efficiency rates measured as a percentage of the sunlight’s photonic energy transferred successfully to alternating current electricity. They had been getting some really good numbers from solar panels, up to twenty percent, but this Stirling engine got thirty, Given the amount of photons raining down, that was really good. That would add up fast.
Then he found a link to a site that explained that Southern California Edison had built a Stirling system to power a 500 megawatt plant; most traditionally-powered plants were 500 or a thousand megawatts, so this was full size. That meant there was some practical experience with real-world, commercial versions of this technology. Also some manufacturing ability, ready to be deployed. All good news when contemplating the need for speed.
Banishing the thought (recurrent about every hour) that they should have been doing this a long time ago, Frank called SCE and asked a long string of questions of the CPM (the Cognizant Program Manager, a useful acronym that only NSF appeared to use). This turned out to be a man who was more than happy to talk – who would have talked all day, maybe all night. With difficulty Frank got him to stop. Lots of enthusiasm for the Stirling system there.
Well, more grist for the mill. Over the past year Frank had been giving alternative energy about a quarter of his working time, and now he saw he was going to have to bump that up. Everything from now on would be jacked to emergency levels. Not a comfortable feeling, but there was no avoiding it. It was like an existential condition, as if he had become Alice’s White Rabbit: I’m late! I’m late! I’m late! And most of the time he managed to obscure from his conscious train of thought the true source of his anxiety.
One day, later that week, when he was deep in work’s oblivion, Diane appeared in his doorway, startling him. He was pleased, then nervous; they had not yet found a new balance. After Caroline had called Frank with her emergency situation, Frank had hastily called Diane to cancel before thinking of any plausible non-other-woman-related reason for doing so, and so had given no explanation at all – which opacity was suspicious, and probably more impolite than the cancellation per se. Opacity seldom conducive to rapport.
‘Hi, Diane,’ he said now, aping normality. ‘What’s happening?’
She looked at him with a curious expression. ‘I just got a call from Phil Chase.’
‘Wow, what did he want?’
‘He asked me if I would be his science advisor.’
Frank found he was standing. He reached out and shook Diane’s hand, then hugged her. ‘Now that is news we have to celebrate,’ he declared, seizing the bull by the horns. ‘I’m sorry about that the other night, I still owe you dinner! Can I take you out tonight?’
‘Sure,’ she said easily, as if there had been no problem. She was so cool; maybe there never had been a problem. Frank couldn’t be sure. ‘Meet you at,’ she checked her watch, ‘at six, okay? Now I’m going to go call my kids.’
But then she stopped on her way out, and again looked at him oddly. ‘You must have had something to do with this,’ she said suddenly.
‘Me? I don’t think so. What do you mean?’
‘Talking to Charlie Quibler, maybe?’
‘Oh, no. I mean, of course I’ve talked to Charlie about some of our stuff, generally –’
‘And he’s been Chase’s environment guy.’
‘Well yes, but you know, Charlie’s just part of a large staff, and he’s been staying at home with Joe, so he hasn’t been a major factor with Chase for some time, as I understand it. Mostly just a voice on the phone. He says he doesn’t get listened to. He says he’s kind of like Jiminy Cricket was to Pinocchio, when Pinocchio’s nose was at its longest.’
Diane laughed. ‘Yeah sure. Let’s meet over at Optimodal, shall we? Let’s say seven instead of six. I want to run some of this off.’
Now that was something he could understand. ‘Sure. See you there.’
Frank sat in his chair feeling his chest puffed out: another cliché revealed to be an accurate account of emotion’s effects on the body. Everyone was the same. It occurred to him that maybe Charlie had had something to do with it, after all. Someone had to have advised Chase whom to choose for this post, and as far as Frank knew, Chase and Diane had never met. So – that was interesting.
Frank went over to the Optimodal Health Club just after six, waved to Diane on the elliptical in the next room, and stomped up the stairmaster for the equivalent of about a thousand vertical feet. After that he showered and dressed, getting into one of his ‘nicer’ shirts for the occasion, and met Diane out in the lobby at the appointed time. She too had changed into something nice, and for a second Frank considered the possibility that she lived out of her office and Optimodal, just as he had contemplated doing before building his treehouse. What evidence did he or anyone else have to disprove it? When they arrived in the morning she was there, when they left at night she was there. There were couches in her big office, and she went to Optimodal every morning of the week, as far as he knew.…
But then again, she certainly had a home somewhere. Everyone did, except for him. And the bros in the park. And the fregans and ferals proliferating in the metropolis. Indeed some twenty or thirty million people in America, he had read. But one thought of everyone as having a home.
Enough – it was time to refocus on the moment and their date. It had to be called that. Their second date, in fact – the first one having occurred by accident in New York, after discussing the North Atlantic project at the UN. And now they were in a Lebanese restaurant in Georgetown that Diane had recently discovered.
And it was very nice. Now they could celebrate not only the actual salting itself, but its subsequent success in restarting the thermohaline; and now, also, Diane’s invitation to become the new Presidential science advisor.
She was pleased with this last, Frank could see. ‘Tell me about it,’ he said to her when they were settled into the main course. ‘Is it a good position? I mean, what does the science advisor do?’ Did it have any power, in other words?
‘It all depends on the President,’ Diane said. ‘I’ve been looking into it, and it appears the position began as Nixon’s way of spanking the science community for publicly backing Johnson over Goldwater. He sent NSF packing out here to Arlington, and abolished his science advisory committee, and established this position. So it became a single advisor he could appoint without any consultation or approval mechanism, and then he could stick them on the shelf somewhere. Which is where these people have usually stayed, except in a few instances.’
That didn’t sound good. ‘But?’
‘Well, in theory, if a president were listening, it could get pretty interesting. I mean, clearly there’s a need for more coordination of the sciences in the federal government. We’ve seen that at NSF. Ideally there would be a cabinet post, you know, some kind of Department of Science, with a Secretary of Science.’
‘The science czar.’
‘Yes.’ She was wrinkling her nose. ‘Except that would create huge amounts of trouble, because really, most of the federal agencies are already supposed to be run scientifically, or have science as part of their subject, or in their operation. So if someone tried to start a Department of Science, it would poach on any number of other agencies, and none of them would stand for it. They would gang up on such an advisor and kill him, like they did to the so-called intelligence czar when they tried to coordinate the intelligence agencies.’
This gave Frank a chill. ‘Yeah, I guess that’s right.’
‘So, now, maybe the science advisor could act like a kind of personal advisor. You know. If we presented a menu of really robust options, and Chase chose some of them to enact, then … well. It would be the President himself advocating for science.’
‘And he might want to do that, given the situation.’
‘Yes, it seems that way, doesn’t it? Although Washington has a way of bogging people down.’
‘The swamp.’
‘Yes, the swamp. But if the swamp freezes over’ – they laughed – ‘then maybe we can iceskate over the obstacles!’
Frank nodded. ‘Speaking of which, we were supposed to be going to try iceskating down here, when the river froze over.’
‘That’s right, we were. But now we’ve got this so-called heat spell.’
‘True. Return of the Gulf Stream.’
‘That is so crazy. I bet we will get freezing spells just like before.’
‘Yes. Well, until that happens maybe we can just walk the shore then, and see where you could rent ice skates when the time comes.’
‘Sure. I think the Georgetown Rowing Club is going to do it, we can go check it out. I read they’re going to convert to a skating center when the river freezes over. They’re going to put out floodlights and boundary lines and everything.’
‘Good for them! Let’s go take a look after dinner.’
And so they finished the meal cheerfully, moving from one great Levantine dish to the next. Even the basics were exquisite: olives, hummus, dill – everything. And by the time they were done they had split a bottle of a dry white wine. They walked down to the Potomac arm-in-arm, as they had in Manhattan so very briefly; they walked the Georgetown waterfront, where the potted shrubs lining the river wall were lit by little white Christmas tree lights. All this had been overwhelmed in the great flood, and they could still see the high water mark on the buildings behind the walk, but other than that, things were much as they had been before, the river as calm as a sheet of black silk as it poured under the Key Bridge.
Then they came to the mouth of Rock Creek, a tiny little thing. Following it upstream in his mind, Frank came to the park and his treehouse, standing right over a bend in this same creek – and thus it occurred to him to think, Here you are fooling around with another woman while your Caroline is in trouble God knows where. What would she think if she saw you?
Which was a hard thought to recover from; and Diane saw that his mood had changed. Quickly he suggested they warm up over drinks.
They retired to a bar overlooking the confluence of the creek and the river, on the Georgetown side. They ordered Irish coffees. Frank warmed up again, his sudden stab of dread dispelled by Diane’s immense calmness, by the aura of reality that emanated from her. It was reassuring to be around her; precisely the opposite of the feeling he had when –
But he stayed in the moment. He agreed with Diane’s comment that Irish coffee provided the perfect compound of stimulant and relaxant, sugar and fat, hydration and warmth. ‘It must have been invented by scientists,’ she said. ‘It’s like made to a formula to hit all the receptors at once.’
Frank said, ‘I remember it’s what they always used to serve at the Salk Institute after their seminars. They’ve got a patio deck overlooking the Pacific, and everyone would go out with Irish coffees and watch the sunset.’
‘Nice.’
Later, as Frank walked her back up through Georgetown to her car, she said, ‘I was wondering if you’d be interested in joining my advisory staff. It would be an extension of the work you’ve been doing at NSF. I mean, I know you’re planning to go back to San Diego, but until then, you know … I could use your help.’
Frank had stopped walking. Diane turned and glanced up at him, shyly it seemed, and then looked away, down M Street. The stretch they could see looked to Frank like the Platonic form of a Midwestern main street, totally unlike the rest of D.C.
‘Sure,’ Frank heard himself say. He realized that in some sense he had to accept her offer. He had no choice; he was only in D.C. now because of her previous invitation to work on the climate problem, and he had been doing that for a year now. And they were friends, they were colleagues; they were … ‘I mean, I’ll have to check with my department and all first, to make sure it will all be okay at UCSD. But I think it could be really interesting.’
‘Oh good. Good. I was hoping you’d say yes.’
The next morning, at work his doorway darkened, and he swung his chair around, expecting to see Diane, there to discuss their move to the Presidential science advisors’ offices –
‘Oh! Edgardo!’
‘Hi, Frank. Hey, are you up for getting a bite at the Food Factory?’ Waggling his eyebrows Groucho-istically.
‘Sure,’ Frank said, trying to sound natural. It was hard not to look around his office as he saved and shut the file he was working on.
On the way to the Food Factory, Edgardo surreptitiously ran a wand over Frank, and gave it to Frank, who did the same for him. Then they went in and stood at a bar, noisily eating chips and salsa.
‘What is it?’
‘A friend of mine has tracked down your friend and her husband.’
‘Ah ha! And?’
‘They work for a unit of a black agency called Advanced Research and Development Agency Prime. The man’s name is Edward Cooper, and hers is Caroline Churchland. They ran a big data mining effort, which was a combination of the Total Information Awareness project and some other black programs in Homeland Security.’
‘Wait – she didn’t work for him?’
‘No. My friend says it was more like the other way around. She headed the program, but he was brought in to help when some surveillance issues cropped up. He came from Homeland Security, and before that CIA, where he was on the Afghanistan detail. My friend says the program got a lot more serious when he arrived.’
‘Serious?’
‘Some surveillance issues. My friend didn’t know what that meant. And then this attempt on the election that she tipped us to.’
‘But he worked for her?’
‘Yes.’
‘And when did they get married?’
‘About two years before he joined her project.’
‘And he worked for her.’
‘That’s what I was told. Also, my friend thinks he probably knows where she’s gone.’
‘What!’
‘That’s what he told me. On the night she disappeared, you see, there was a call from a pay phone she had used before, a call to the Khembali embassy. I take it that was to you?’
‘She left a message,’ Frank muttered, more and more worried. ‘But so?’
‘Well, there was another call from that pay phone, to a number in Maine. My friend found the address for that number, and it’s the number of your friend’s college roommate. And that roommate has a vacation home on an island up there. And the power has just been turned on for that vacation home. So he thinks that’s where she may have gone, and, as I’m sure you can see, he furthermore thinks that if he can track her that well, at his remove, then her husband is likely to be even faster at it.’
‘Shit.’ Frank’s feet were cold.
‘Shit indeed. Possibly you should warn her. I mean, if she thinks she’s hidden herself –’
‘Yeah, sure,’ Frank said, thinking furiously. ‘But another thing – if her ex could find her, couldn’t he find me too?’
‘Maybe so.’
They regarded each other.
‘We have to neutralize this guy somehow,’ Frank said.
Edgardo shook his head. ‘Do not say that, my friend.’
‘Why not?’
‘Neutralize?’ He dragged out the word, his expression suddenly black. ‘Eliminate? Remove? Equalize? Disable? DX? Disappear? Liquidate?’
