"This article takes stock of current knowledge of climate change and the response to this major problem affecting the environment and economic development. It begins with a brief review of climate change science and impacts as assessed by the Intergovernmental Panel on Climate Change. It then reports on the status of the United Nations Framework Convention on Climate Change and its Kyoto Protocol, and summarizes national commitments to making the effort required to mitigate climate change by limiting the emission of greenhouse gases. The main issues still to be addressed are identified, focusing in particular on carbon markets and adaptation funding. Future prospects are considered, including possible emissions targets for developing countries. The article thus focuses on the key issues of concern for developing countries."
