Book excerpt: Recently, large parts of the world faced record high temperatures–another item on a long list of warning signs about the climate. This book is for the reader interested in having a better understanding of the nature and causes of climate change and the measures being undertaken. Global Climate Change suggests success is unlikely and to prevent catastrophe, more radical and uncomfortable actions will be needed. Many groups in society (e.g. governments, economies, businesses, public services) will need to undertake such actions to mitigate climate change and deal with its consequences. This book provides guidance about what these actions will involve.
