Ancient air bubbles yield greenhouse-gas concerns

By LAURAN NEERGAARD,The Associated Press, Published in The Seattle Times.


"Levels of carbon dioxide have climbed from 280 parts per million two centuries ago to 380 ppm today. Earth's average temperature, meanwhile, increased about 1 degree Fahrenheit in recent decades, a relatively rapid rise. Many climate specialists warn that continued warming could have severe impacts, such as rising sea levels and changing rainfall patterns.""



"that rise is occurring at a speed that "is over a factor of a hundred faster than anything we are seeing in the natural cycles," Stocker added. "It puts the present changes in context."
