Plus ça change, plus c'est la même chose: A group of scientists considered experts on world climate called Saturday on all nations to take immediate steps to control global warming, regardless of the many questions that still exist about man-made climate change. The scientists, at the Second World Climate Conference here, completed their report late Saturday and made it public today. They said in a statement that the technology already exists to make substantial cuts in the emission of harmful gases without jeopardizing economic growth.
