600ppm a novel of climate change

It's 2051. Global warming has flooded eastern U.S. coastal cities. The West is a waterless desert. Refugees migrate northward. Food and water are tightly rationed amid endless war. When Jeff Claymarker's friend is wrongly convicted of murder, the only clue to the truth comes from a stash of flash drives belonging to Jeff's late uncle, a Washington climate scientist. As Jeff unravels the crime, he stumbles across a state secret that threatens to topple the government.
