The year 2009 will be pivotal for Earth's climate. As scientists warn that we have only a few years to reverse the rise in greenhouse gas emissions if we are to avoid abrupt and catastrophic climate change, the world community has agreed to finalize negotiations on a new climate agreement in Copenhagen in late 2009. Intended to inject new inspiration and energy into national and international climate negotiations, this 26th edition of State of the World examines the steps we urgently need to take to prevent a global catastrophe while adapting to the now inevitable climatic shifts already set in motion. As well as the profound, long-term consequences of global warming, this volume explores the policy changes needed and the benefits that will flow from the transition to a low-carbon economy. It also includes 22 summaries on the many important issues linked to climate change, plus a Climate Change Reference Guide and Glossary. Published annually in 28 languages, State of the World is long established as the most authoritative and accessible annual guide to our progress towards a sustainable future. It is relied upon by national governments, UN agencies, development workers and law-makers for its up-to-the-minute analysis and information. Essential reading for anyone concerned with building a positive, global future.
