Released biennially by the United Nations Development Programme, the Human Development Report offers informed commentary and analysis of issues that affect humans across the world. In past years, the report has dealt with civil wars, starvation, economic growth, gender inequality, and a wide range of pressing matters. Released at the end of November 2007, this edition of the Human Development Report takes on the development impact of climate change "that could bring unprecedented reversals in poverty reduction, nutrition, health and education." The 399-page report offers a portrait of the challenges presented by widespread climate changes by looking at growth in certain parts of the world, growing carbon footprints, and how developing and developed nations might mitigate some of these changes.
