In this book, leading experts - including several authors of reports by the Intergovernmental Panel on Climate Change and the UK Climate Change Impacts Review Group - examine the background and alternative scenarios for change, as well as its implications. They look in detail at water supply and management, agriculture and land use, energy, and the finance and insurance sector. In each case, they show how current activities will have to adapt and they conclude by evaluating the arguments for prevention now vs adaptation later. The changes in store could be huge, requiring the attention of academics and professionals from a wide range of disciplines and industries, as well as government action. This book makes a major contribution to understanding what is at stake.
