The book is about the impact of war at sea on climate, which showed dramatic effects soon after naval war commenced on 1st September 1939. WWI already had changed course of climate. The facts presented on 178 pages aim to pave the way for a new thinking on climate change issues and that the driving force is the ocean, which ultimately control weather and climate. Two devastating sea wars during the last century prove validity of connection. Naval war altered direction of climate twice.
