likely put off responding adequately to climate change until major catastrophes unequivocally connected to it occur, but by then by definition it would be too late, for we have no way of reversing the build-up of greenhouses gases that is driving the transformation of the world's climate. Some such gases would be in the atmosphere for centuries. Within 'The Politics of Climate Change' Giddens places attention on global environmental conferences such as the 1997 Kyoto summit, whereby an agreement was drawn up so that developed countries would cut their emissions by an average of 5.2 per cent. The Kyoto protocol was to become apart of international law, and the developed countries who accounted for at least 55 per cent of total emissions from the industrial states, would have to sign up. In his latest work, Giddens has returned to the subject of the European Union, discussed in 2007 in his book Europe in the Global Age and in a diversity of articles. In Turbulent and Mighty Continent: What Future for Europe?, he discusses the likely future of the European Union in the wake of the financial crisis of 2007–2008. Giddens writes as a committed pro-European, but he accepts that fundamental reforms must be made if the European Union is to avoid stagnation or worse. The coming of the euro introduced economic federalism among the eurozone countries and therefore to the European Union as a whole. Some version of political federalism must follow, even if limited in nature. Reforms must confer qualities absent from much of the European Union's history, but which are now required for its future such as flexible and quick-acting leadership, coupled to the greater democratic involvement of citizens. However, he also emphasised that European Union "could still founder, even disintegrate, the result of a chain reaction of circumstances that member states were unable to control". In December 2014, Turbulent and Mighty Continent was awarded the European Book Prize, awarded by a selection jury featuring members from many different countries. In recent years, while continuing to pursue some of the core themes of his earlier works he has become preoccupied with the impact of the Digital Revolution on world society and on everyday life. That revolution, he argues, must not be identified solely with the advent of the internet, extraordinary although that is. Rather, the Digital Revolution is a massive wave of change washing across the world, driven
