Book by Kim Stanley Robinson.
This is the third and concluding volume of Kim Stanley Robinson's trilogy about an alternate present or near future when the world is forced to face a catastrophic climate crisis. But this isn't another apocalyptic dread-feast. Extraordinary events shape and bend the everyday, but they don't break it.
Robinson is known as a science fiction writer (his Red/Green/Blue Mars trilogy, etc.) and a futuristic California writer (the Three Californias series). In this volume in particular, he is also an evocative nature writer, describing the wilds of the California Sierras, Maine and Washington, D.C. That he finds wilds in Washington is part of the story.
This trilogy is centered in Washington and follows a group of scientists and politicians as the climate crisis gets real: Antarctic melting leads to massive flooding in Washington and elsewhere, inundating whole island nations and paradoxically leading to a monster winter, with worse to come. In the midst of all this, there's a presidential election.
The first in the series, Forty Signs of Rain, introduces scientist Anna and politico Charlie Quibler, and their children. Through them and other characters, Robinson writes realistically of the various responses to the growing knowledge that the world is in deep climate trouble. Fifty Degrees Below shows the climate crap hitting the fan. It's told mostly through scientist Frank Vanderwal (a close friend of the Quiblers), who loses his home to the floods and experiments with living off the urban land. Vanderwal gets involved with Buddhists on the fictional island of Khembalung, inhabitable because of flooding. He's also has a couple of romances, one with a strange woman who gets him involved in foiling a plot to fix the presidential election.
By the time this third novel begins, a Bush clone candidate has been defeated, and the U.S. has a new president committed to confronting the climate crisis: California Senator Phil Chase, a looser West Coast version of Al Gore, but with Obama's communication skills. The story follows Chase's efforts and thoughts (he has his own presidential blog called "Cut to the Chase"), and those of the scientists in the actions they propose and begin to take.
Except for the fallout of the failed attempt to fix the election in a not very distinguished but still apropos Washington paranoia-thriller plot (surveillance, proliferating intelligence agencies spying on each other, etc.), the novel flows with the lives of those characters. Frank is at the front lines of the scientific efforts, but also living on the grounds of the Khembalung embassy with an elderly Buddhist monk as his roommate. He continues to monitor his friends "living feral" in Washington's parks and abandoned buildings, as well as the animals flooded out of the zoo, also living feral in the extensive parklands in the D.C. area.
In many ways this is the opposite of conventional science fiction dominated by technology, even if scientists are the heroes. On his computer, Frank subscribes to "Emerson for the Day," and both Emerson and Thoreau are guiding spirits. So is Buddhism — in fact, the Dalai Lama appears as a character.
Even President Phil Chase is a philosophical blogger (one who gets five million responses to his first post). By the end he's musing about reclaiming imagination as the human tool to create a dynamic culture that can be permanently sustained, a culture "in which no one is without a job, or shelter, or health care, or education, or the rights to their own life. Taking care of the Earth and its miraculous biological splendor will then become the long-term work of our species. We'll share the world with all the other creatures. It will be an ongoing project that will never end."
This is a very smart novel — on politics, economics, science and those underlying matters of soul. Things happen, that it wouldn't be fair to reveal. But perhaps most surprisingly, it feels like a kind of pastoral, valuing the real Earth and real life that makes keeping humankind from destroying the planet worthwhile. In a technical Shakespearian sense it's even a comedy, because it ends like As You Like It: good people restoring the state, gathered in nature, for weddings.
