Global warming continues as greenhouse gas grows

(AP) -- A study released Tuesday says the world's climate is not only continuing to warm, it's adding greenhouse gases even faster than in the past.

In fact it's been more than 300 months since the average global average temperature was below average.

The annual State of the Climate report said 2010 was tied with 2005 as the hottest year on record, worldwide and added that the greenhouse gas carbon dioxide increased faster than it has in recent decades.

Peter Thorne of North Carolina's Cooperative Institute for Climate and Satellites called the finding "a clear and unmistakable signal from the top of the atmosphere to the depths of the oceans.'
