Carbon dioxide already in danger zone, warns study

A group of 10 prominent scientists says that the level of globe-warming carbon dioxide in the air has probably already reached a point where world climate will change disastrously unless the level can be reduced in coming decades. The study is a departure from recent estimates that truly dangerous levels would be reached only later in this century. The paper appears in the current edition of the Open Atmospheric Science Journal.
