Climate warming gases rising faster than expected



English version

USA Today: Despite widespread concern over global warming, humans are adding carbon to the atmosphere even faster than in the 1990s, researchers warned Saturday.

Carbon dioxide and other gases added to the air by industrial and other activities have been blamed for rising temperatures, increasing worries about possible major changes in weather and climate.

Carbon emissions have been growing at 3.5% per year since 2000, up sharply from the 0.9% per year in the 1990s, Christopher Field of the Carnegie Institution for Science told the annual meeting of the American Association for the Advancement of Science.

"It is now outside the entire envelope of possibilities" considered in the 2007 report of the International Panel on Climate Change, he said.
