Madrid (dpa) - The negotiations at the world climate conference drag into the morning. Conference leader Carolina Schmidt announced at midnight new, from her point of view, improved texts. The conference should have ended on Friday evening, but the states are still far apart in their positions. It was hard, it was difficult, but it was worth going on, she said. Madrid, for example, is discussing rules for international trade in climate protection credits and financial support for the richer industrialized countries for the poorer countries.
