This document discusses the developments in international climate change negotiations from 1979 to 2009. It outlines the key outcomes and paradigms during different time periods. It also discusses the issues being negotiated at the 2009 Copenhagen conference, including long-term emissions reduction targets, targets for developed countries, commitments from developing countries, financial mechanisms, and reducing deforestation. The document argues that the pledges from developed countries to reduce emissions are conditional and allow many loopholes. There are also concerns about how commitments from developing countries will be implemented and whether actions will actually be taken.
