Climate change differs from any other problem that, as collective humanity, we face today. If it goes unchecked, the consequences are likely to be catastrophic for human life on earth. Yet for most people, and for many policy-makers too, it tends to be a 'back of the mind' issue. We recognise its importance and even its urgency, but for the most part it is swamped by more immediate concerns. Politicians have woken up to the dangers, but at the moment their responses are mainly on the level of gesture rather than being, as they have to be, both concrete and radical.

Political action and intervention, on local, national and international levels, is going to have a decisive effect on whether or not we can limit global warming, as well as how we adapt to that already occurring. At the moment, however, Anthony Giddens argues controversially, we do not have a systematic politics of climate change. Politics-as-usual won't allow us to deal with the problems we face, while the recipes of the main challenger to orthodox politics, the green movement, are flawed at source. Giddens introduces a range of new concepts and proposals to fill in the gap, and examines in depth the connections between climate change and energy security.

This book is likely to become a classic in the field. It will be of appeal to everyone concerned about how we can cope with what amounts to a crisis for our civilisation.

Anthony Giddens, Baron Giddens (born 8 January 1938) is a British sociologist who is known for his theory of structuration and his holistic view of modern societies. He is considered to be one of the most prominent modern contributors in the field of sociology, the author of at least 34 books, published in at least 29 languages, issuing on average more than one book every year. In 2007, Giddens was listed as the fifth most-referenced author of books in the humanities.

Three notable stages can be identified in his academic life. The first one involved outlining a new vision of what sociology is, presenting a theoretical and methodological understanding of that field, based on a critical reinterpretation of the classics. His major publications of that era include Capitalism and Modern Social Theory (1971) and New Rules of Sociological Method (1976). In the second stage Giddens developed the theory of structuration, an analysis of agency and structure, in which primacy is granted to neither. His works of that period, such as Central Problems in Social Theory (1979) and The Constitution of Society (1984), brought him international fame on the sociological arena.

The most recent stage concerns modernity, globalization and politics, especially the impact of modernity on social and personal life. This stage is reflected by his critique of postmodernity, and discussions of a new "utopian-realist" third way in politics, visible in the Consequence of Modernity (1990), Modernity and Self-Identity (1991), The Transformation of Intimacy (1992), Beyond Left and Right (1994) and The Third Way: The Renewal of Social Democracy (1998). Giddens's ambition is both to recast social theory and to re-examine our understanding of the development and trajectory of modernity.

Giddens served as Director of the London School of Economics 1997–2003, where he is now Emeritus Professor.

He is also a member of the Advisory Board of the Institute for Cultural Diplomacy.
