Before you make up your mind about climate change you are advised to read this controversial, compelling book Nexus. Scientists agree that the earth has become hotter over the last century. But on the causes, despite what looks to the public mind like a consensus, there are dissenting voices.

As prize-winning science writer Nigel Calder and Svensmark himself explain, an interplay of the sun and cosmic rays sub-atomic particles from exploded stars seem to have more effect on the climate than man-made carbon dioxide. For anyone interested in the real science behind our climate, this book is a must-read.
