But survival did not have to depend on waiting for evolution to choose the winners.… By the end of the century, people stopped asking whether Earth would become warmer. They knew it would. The more difficult question was what would happen to the human body. Dr. Ren Takahashi worked at the International Institute for Human Adaptation, a research center built outside Sapporo. His specialty was thermophysiology—the study of how organisms maintain a stable internal temperature while the environment changes. His students often summarized his lectures with a single sentence: “Humans can adapt to heat.” Ren always corrected them. “No. Humans can acclimatize to heat. Evolution is something else.” He explained the distinction carefully. When a person moved from a cool climate to a hot one, the body could change within days or weeks. Sweating could begin earlier. Plasma volume could increase. The cardiovascular system could become more efficient at moving blood tow...

It had taken them ten years to discover it.… Mika had done her homework before marrying Daichi. She had asked mutual friends about him. She had quietly checked his social-media accounts, learned what sort of company he worked for, and made sure there was no girlfriend hiding somewhere in the background. She even asked one of his former coworkers what he was like when nobody was trying to impress him. The answer was reassuring. Daichi was generous. Easygoing. Dependable. He worked hard and rarely complained. What Mika did not discover was that he was not especially healthy, had little enthusiasm for his actual job, and still owed a substantial amount on his car. She knew about the car loan. She simply assumed it would disappear. He had a salary. She had a salary. Two salaries meant two incomes, and two incomes, she thought, meant a comfortable household. That calculation turned out to be dangerously simple. Daichi’s generosity ...

The one that existed nowhere— except inside her mind.… At twenty-three, Mara believed that becoming a painter was simply a matter of drawing enough. So she drew. During the day, she worked at a small flower shop near the rented room where she lived. She arranged bouquets, trimmed stems, changed the water in buckets, swept petals from the floor, and learned the names of flowers that arrived from farms and wholesalers before sunrise. At closing time, the shop usually discarded flowers that were beginning to wilt or had been damaged during transport. Mara was allowed to take some home. She began with roses. Then tulips. Then irises. But eventually, she became obsessed with lilies. She loved their geometry: the long, curved petals, the six stamens emerging from the center, the way the flower seemed simultaneously delicate and almost architectural. She drew them from different angles, under different lamps, with the petals ope...

Just people trying to make sure that, when the next person looked up from the ground, someone had given them a reason to wave.… Ted had spent most of his adult life learning how to make decisions when there was never enough of anything. Not enough beds. Not enough nurses. Not enough laboratory capacity. Not enough time. And, in the poorer hospitals he had once worked in, sometimes not enough antibiotics. Now, at fifty-two, he was no longer simply the senior physician at the local public hospital. A recent promotion had placed him in charge of clinical coordination across five hospitals in the region. He was expected to standardize treatment protocols, review serious incidents, negotiate with administrators, and help decide which medicines and medical devices the public system would purchase. It was precisely the sort of position that made people who sold medical products suddenly become very interested in his calendar. Matt was one of those people. He had...
