Icecap: A novel of unexpected consequences

A scientifically-defensible novel about a few of the oddities in human affairs that are triggered by the collapse of the Greenland Ice Cap - an event which can happen as described, in a single day. Although only raising mean sea level by about 14 cm, the event causes an atomic-weapons-level international conflict. The collapse also shuts off the Gulf Stream, thereby radically changing the climate of the British Isles, Scandinavia, and much of continental Europe. Ultimately, that 14cm of sea-level rise leads to partial destruction of the Antarctic Ice Cap.
