In the six years since the first edition of this book was published the interaction between the ocean and climate has remained at the centre of climate investigation. New emphasis on abrupt climate change triggered by freshwater changes to the ocean's surface, and the interaction between the ocean's thermohaline circulation and climate on millennial timescales has arisen. Hence this edition, as well as updating the science generally, has added significant new sections in Chapters 2 and 5 to reflect this enhanced importance of thermohaline processes. Modelling is becoming increasingly important, and hence treatment of this tool has been moved forward to Chapter 1. Nevertheless, the basic science on which the first edition was built has been supplemented rather than overturned during these last active years. Thus readers will find the basic structure of the book similar to before, but brought up-to-date where necessary.
In the last edition I was unfortunate in the timing of publication relative to the IPCC series of reports, completing the writing of the book prior to the issue of the 1995 report. This time I benefit from the recent publication of the 2001 reports, enabling me to give timely revisions of the international community's views on climate change and the ocean's role in this. I therefore thank my editor, Matt Lloyd for prompting the second edition at the right time. Once again, I also have to thank Phil Judge for drawing many new diagrams or revising old ones, and Sheila Davies for supplying the photographic versions. The continuing rise of the web as a medium for science communication and education leads me to provide a web-page for the book with relevant links to many valuable sites concerned with the science, and provision of data, for climate study. I hope readers find this edition even more stimulating than the last!
