She and Art talked the situation over as they served the people in the apartment tea. Spy or not, Art knew Terra, and had an incisive political judgment, which she found helpful. He was like a mellow Frank. Was that right? Somehow she was reminded of Frank, and though she couldn’t pin down why, she was obscurely pleased. No one else could have seen any resemblance in this lumbering sly man, it was her perception and hers alone.

Then more people began to crowd into the apartment, cell leaders and visitors from out of town. Maya sat at the back and listened as Jackie spoke to them. Everyone in the resistance, Maya thought as she listened to her, was in it for themselves. The way Jackie used her grandfather as a symbol, waving him like a flag to rally her troops, was sickening. It wasn’t John who had gotten her her followers, but her white scoop blouse, the slut. No wonder Nirgal was estranged from her.

Now she exhorted them with her usual incendiary message, enthusiastically advocating immediate rebellion, no matter what the agreed-upon strategy was. And to these so-called Booneans, Maya was nothing more than an old paramour of the great man, or perhaps the reason he had been killed: a fossil odalisque, a historical embarrassment, an object of men’s desire, like Helen of Troy called back by Faustus, insubstantial and weird. Ach, it was maddening! But she kept a calm face, and got up and walked in and out of the kitchen with her head averted, doing what paramours did, keeping people comfortable and fed. Nothing more to be done, at this point.

She stood in the kitchen, staring out the window at the rooftops below. She had lost whatever influence she had ever had on the resistance. The whole thing was going to come unraveled before Sax or any of the rest of them who counted were ready. Jackie was ranting on cheerily in the living room, organizing a demonstration that might get ten thousand people into the park, maybe fifty, who could say? And if security responded with tear gas and rubber bullets and truncheons, people would get hurt, some killed; killed for no strategic purpose, people who might have lived a thousand years. And still Jackie went on, bright and enthusiastic, burning like a flame. Overhead the sun gleamed through a break in the clouds, bright silver, ominously large. Art came into the kitchen and sat at the table, switching on his AI and sticking his face into it. “Got a note from home Praxis on the wrist.” He read the screen, nose practically touching it.

“Are you nearsighted?” Maya said irritably.

“I don’t think so … oh man. Ka boom. Is Spencer out there? Get Spencer in here.”

Maya went to the doorway and signaled Spencer, who came in.-Jackie ignored the disturbance and went on talking. Spencer sat down at the kitchen table beside Art, who was. now sitting back, round-eyed and round-mouthed. Spencer read for five seconds and sat back in his chair, looked over at Maya with a strange expression. “This is it!” he said.

“What?”

“The trigger.”

Maya went to him and stood reading over his shoulder.

She held on to him, feeling a bizarre sensation of weightlessness. No more staving off the avalanche. She had done her job, she had just barely done it. At the very moment of failure, fate had turned.

Nirgal came into the kitchen to ask what was going on, attracted by something in their low voices. Art told him and his eyes lit, he couldn’t conceal his excitement. He turned to Maya and said, “It’s true?”

She could have kissed him for that. Instead she nodded, not trusting herself to speak, and went to the doorway to the living room. Jackie was still in the midst of her exhortation, and it gave Maya the greatest of pleasure to interrupt her. “The demonstration’s off.”

“What do you mean?” Jackie said, startled and annoyed. “Why?”

“Because we’re having a revolution instead.”

PART 10

Phase Change

They were pelican surfing when apprentices jumping up and down on the beach alerted them that something was wrong. They flew back in to the beach and stuck their landings on the wet sand, and got the news. An hour later they were up to the airport, and soon after that taking off in a little Skunkworks space plane called the Gollum. They headed south, and when they reached 50,000 feet they were somewhere over Panama, and the pilot tilted it up and kicked in the rockets, and they were pressed back in their big g chairs for a few minutes. The three passengers were in cockpit seats behind the pilot and copilot, and out their windows they could see the exterior skin of the plane, which looked like pewter, begin to glow, and then quickly turn a vivid glowing yellow with a touch of bronze to it, brighter and brighter until it looked as if they were Shadrach, Meshach and Abednego, sitting together in the fiery furnace and coming to no harm.

When the skin lost some of its glow, and the pilot leveled them off, they were about eighty miles above the Earth, and looking down on the Amazon, and the beautiful spinal curve of the Andes. As they flew south one of the passengers, a geologist, told the other two more about the situation.

“The West Antarctic ice sheet was resting on bedrock that is below sea level. It’s continental land, though, not ocean bottom, and under West Antarctica it’s a kind of basin and range zone, very geothermally active.”

“West Antarctica?” Fort asked, squinting.

“That’s the smaller half, with the peninsula sticking up toward South America, and the Ross ice shelf. The west ice sheet is between the mountains of the peninsula and the Transantarctic Mountains, in the middle of the continent. Here, look, I brought a globe.” He pulled from his pocket an inflatable globe, a child’s toy, and blew it up and passed it around the cockpit.

“So, the western ice sheet, there, was resting on bedrock below sea level. But the land down there is warm, and there are some under-ice volcanoes down there, and so the ice on the bottom gets melted a bit. This water mixes with sediments from the volcanoes, and forms a substance called till. It has a consistency kind of like toothpaste. Where the ice is riding over this till it moves faster than usual, so within the west ice sheet there were ice streams, like fast glaciers with their banks made of slower ice. Ice Stream B ran two meters a day, for instance, while the ice around it moved two meters a year. And B was fifty kilometers across, and a kilometer deep. So that was one hell of a river, running off with about half a dozen other ice streams into the Ross ice shelf.” He indicated these invisible streams with a fingertip.

“Now, where the ice streams and the ice sheet in general came off the bedrock, and started floating in the Ross Sea — that was called the grounding line.”

“Ah,” said one of Fort’s friends. “Global warming?”

The geologist shook his head. “Our global warming has had very little effect on all this. It’s raised temperatures and sea levels a little bit, but if that was all that was happening it wouldn’t make much difference here. The problem is we’re still in the interglacial warming that began at the end of the last Ice Age, and that warming sends what we call a thermal pulse down through the polar ice sheets. That pulse has been moving down for eight thousand years. And the grounding line of the west ice sheet has been moving inland for eight thousand years. And now one of the under-ice volcanoes down there is erupting. A major eruption. About three months old now. The grounding line had already started to retreat at an accelerated rate some years ago, and it was very close to the volcano that’s erupted. It looks like the eruption has brought the grounding line right to the volcano, and now ocean water is running between the ice sheet and the bedrock, right into an active eruption. And so the ice sheet is breaking up. Lifting up, sliding out into the Ross Sea, and being carried away by currents.”
