By 2052, with soaring temperatures, extreme storms, and rising ocean levels, climate change has ceased to be a matter for debate. Food shortages are rampant, entire nations starve, and the earth’s wild places and species are vanishing. 

Presidential candidate George Cranston of the Federalist party is fully aware of the challenges facing the planet and determined to tackle them. Before he can do anything, however, he must defeat his rival from the dominant and corrupt Doctrinist party - a daunting task given the Doctrinists’ determination to hang on to power at any cost. 

News of a massive, mysterious object under construction in China gives the Doctrinists a weapon to wield against Cranston, whose running mate, Dr. Lilly McDowell, began life as a Chinese orphan. His rivals assume the “Chinese Device” is a weapon. Cranston’s not so sure. 

As the battle for the White House continues, people across the globe struggle against the consequences of climate change, including in Nigeria which is being battered from the north by the Sahara and from the south by the rising ocean, scientists in Borneo and on the Galápagos Islands fight to save their worlds, and a young American astronaut who is thrust into the middle of a global crisis. 

Offering a harrowing and all-too-likely glimpse of the near future, Three Degrees is a complex, character-driven novel that explores the changes climate change could bring to our world.
