A small contrite cough just behind them made both girls start. It was the first time anyone apart from the stewards had even acknowledged they existed. When they turned round they found themselves facing a small man in a dark purple business suit. He’d already got some thin wrinkles on his cheeks, though he didn’t seem particularly old. Louise was surprised by his height, she was actually an inch taller than him, and he had a very broad forehead, as if his hair wouldn’t grow properly along the top of it.
“I know this is rude,” he said quietly. “But I believe you’re from outsystem?”
Louise wondered what had given them away. She’d bought the pair of them new clothes in Skyhigh Kijabe, one-piece garments like shipsuits but more elaborate, with pronounced pockets and cuffs. Other women were wearing the fashion; so she’d hoped they would blend in.
“Yes,” Louise said. “From Norfolk, actually.”
“Ah. I’m afraid I’ve never tasted Norfolk Tears. Too expensive, even with my salary. I was most sorry to hear about its loss.”
“Thank you.” Louise kept her face blank, the way she’d learned to do whenever Daddy started shouting.
The man introduced himself as Aubry Earle. “So this is your first visit to Earth?” he asked.
“Yes,” Genevieve said. “We want to go to Tranquillity, but we can’t find a flight.”
“I see. Then this is all new to you?”
“Some of it,” Louise said. She wasn’t quite sure what Aubry wanted. He didn’t seem the type to befriend a pair of young girls. Not from altruism, anyway.
“Then allow me to explain what you are seeing. The oceans aren’t polluted, at least not seriously; there was an extensive effort to clean them up at the end of the Twenty-first Century. Their present colouring comes from algae blooms. It’s a geneered variety that floats on the top. I think it looks awful, myself.”
“But it’s everywhere,” Genevieve said.
“Alas, yes. That’s our carbon sink these days. Earth’s lungs, if you like. It performs the job once done by forests and grasslands. The surface vegetation is not what it used to be, so Govcentral introduced the algae to prevent us from suffocating ourselves. Actually, it’s a far more successful example of terraforming than Mars. Though I would never be so undiplomatic as to say that to a Lunar citizen. We now have less carbon dioxide in our atmosphere than at any time in the last eight hundred years. You’ll be breathing remarkably clean air when you arrive.”
“So why do you all live in the arcologies?” Louise asked.
“Heat,” Aubry said sadly. “Do you know how much heat a modern industrial civilization of over forty billion people generates?” He gestured down at the globe. “That much. Enough to melt the polar ice and quicken the clouds. We’ve taken all the preventative measures we can, of course. That was the original spur to build the orbital towers, to prevent spaceplanes aerobraking and shedding even more heat into the air. But however economic we are, we can’t dissipate it at a rate that’ll turn the clock back. The old ocean currents have shut down, there’s no ozone layer at all. And that kind of ecological retro-engineering is beyond even our ability. We’re stuck with the current environment, unfortunately.”
“Is it very bad?” Genevieve asked. What he’d described sounded worse than the beyond, though she thought the man didn’t sound terribly upset by the cataclysm.
He smiled fondly at the planet. “Best damn world in the Confederation. Though I expect everyone says that about their homeworld. Am I right?”
“I like Norfolk,” Louise said.
“Of course you do. But if I might make an observation, this is going to be noisier than anything you’ve experienced before.”
“I know that.”
“Good. Take care down there. People aren’t likely to help you. That’s our culture, you see.”
Louise gave him a sideways look. “Do you mean they don’t like foreigners?”
“Oh no. Nothing like that. It’s not racism. Not overtly, anyway. On Earth everybody is a foreigner to their neighbour. It’s because we’re all squashed up so tight. Privacy is a cherished commodity. In public places, people don’t chat to strangers, they avoid eye contact. It’s because that’s the way they want to be treated. I’m really breaking taboos by talking to you. I doubt any of the other passengers will. But I’ve been outsystem myself, I know how strange it all is for you.”
“Nobody’s going to talk to us?” Genevieve asked apprehensively.
“Not as readily as I.”
“That’s fine with me,” Louise said. She couldn’t quite bring herself to trust Aubry Earle. At the back of her mind was the worry that he would volunteer to become their guide. It had been bad enough in Norwich when she’d depended on Aunt Celina; Roberto was family. Earle was a stranger, one prepared to drop Earth’s customs in public when it suited him. She gave him a detached smile, and led an unprotesting Gen away from the window. The lift capsule had ten decks, and her standard-class ticket allowed her into four of them. They managed to avoid Earle for the rest of the flight. Though she realized he was telling the truth about privacy. Nobody else talked to them.
The isolation might have been safer, but it made the ten hour trip incredibly boring. They spent a long time watching the view through the window as Earth grew larger, and talking idly. Louise even managed to sleep for the last three hours, curling up in one of the big chairs.
She woke to Gen shaking her shoulder. “They just announced we’re about to reach the atmosphere,” her sister said.
Louise combed some strands of hair from her face, and sat up. Other passengers who’d been dozing were now stirring themselves. She took the hair clip off as she reorganized her mane, then fastened it up again. First priority when they were down must be to get it washed. The last time she’d managed properly was back on Phobos. Maybe it was time for a cut, a short style that was more manageable. Though the usual arguments still applied: she’d invested so much time keeping it in condition, cutting it was almost a confession of defeat. Of course, back at Cricklade she’d had the time to groom herself every day, and had a maid to help.
Whatever did I do all day back then?
“Louise?” Genevieve asked cautiously.
She raised an eyebrow at the girl’s tone. “What?”
“Promise you won’t get mad if I ask?”
“I won’t get mad.”
“It’s just that you haven’t said yet.”
“Said what?”
“Where we’re going after we touch down.”
“Oh.” Louise was completely stumped. She hadn’t even thought about their destination. Getting away from High York and Brent Roi had been her absolute priority. What she needed to do was find somewhere to stay so she could think about what to do next. And without consulting her block there was really only one city name from her ethnic history classes which she was certain would still exist. “London,” she told Genevieve. “We’re going to London.”
The African orbital tower had been the first to be built, a technological achievement declared the equal of the FTL drive by the Govcentral committees and politicians who’d authorized it. Typical self-aggrandising hyperbole, but acknowledged to be a reasonable comparison none the less. As Aubry Earle had said, it was intended to replace spaceplanes and the enormously detrimental effect they were having on Earth’s distressed atmosphere. By 2180 when the tower was finally commissioned (eight years late), the Great Dispersal was in full swing, and the volume of spaceplane traffic had become so injurious to the atmosphere that meteorologists were worrying about elevating the armada storms to an even greater level of ferocity.
The question became academic. Once the tower was on line, its cargo capacity exceeded thirty per cent of the world’s spaceplane fleet. Upgrades were being planned before the first lift capsule ran all the way up to Skyhigh Kijabe. Four hundred and thirty years later, the original slender tower of monocarbon fibre was now nothing more than a support element threading up the centre of the African Tower. A thick grey pillar dwindling off up to infinity, immune to the most punishing winds the armada storms could fling at it. The outer surface was lined with forty-seven magnetic rails, the structure’s maximum. It was now cheaper to build new towers than expand it any further.
