CNN (Reuters) reports that it's about to get much much warmer here on Earth. As much as 20 degrees warmer.

Greenhouse gas emissions could cause global temperatures to rise by up to 11 degrees Celsius (20 degrees Fahrenheit), according to first results from the world's largest climate modeling experiment.

The top end of the predictions, which range from 2-11 degrees, is double estimates produced so far and could make the world dramatically different in the future.

Why they chose to emphasize the upper extremity isn't clear. If I didn't know better I would almost think there was some sort of inherent media bias. The top end is between 2 and 20 degrees, yet they emphasize 20 degrees.

For those of you keeping score, scientists are predicting that the earth will warm by somewhere between 1 and 40 degrees over the next 20 to 100 years. And they note that if it doesn't get warmer, it'll probably get cooler or stay about the same.
