What is this «Blue Planet» am I living on?

This book takes the reader on a voyage around the world, guided by Hervé Le Treut, a climatologist and member of the GIEC. We learn about all the factors that affect climate: oceans, the atmosphere, clouds, human beings, continents… Our climate changes naturally from day to day, from month to month and from year to year – but which changes are really linked to global warming? We may know for certain that temperatures are going to change everywhere, but we don’t yet know how or why. It is because of its atmosphere and its water and carbon cycles – vital to life – that Earth functions as a life-supporting “machine”. We know about each separate element but we don’t yet understand how the “machine” is triggered off or even how the whole thing really works. The book explains the various factors that affect climate and how they are linked, and tells us which questions remain unanswered.
