In other words, in 2010, humanity (with a special bow to China, the United States, and onrushing India) managed to pump more carbon dioxide into the atmosphere than at any time since the industrial revolution began -- 564 million more tons than in 2009, which represents an increase of 6%.According to AP’s Seth Borenstein, that’s “higher than the worst case scenario outlined by climate experts just four years ago.” He’s talking about the Intergovernmental Panel on Climate Change, or IPCC, which is, if anything, considered "conservative" in its projections of future catastrophe by many climate scientists. Put another way, we’re talking more greenhouse gases than have entered the Earth’s atmosphere in tens of millions of years.
Global warming likely won't reach extremely catastrophic temperatures even if carbon dioxide levels double, climate researchers suggest.
