New analysis (pdf) of climate data finds that since 1912, the United States has warmed 1.3 degrees. But that warming is concentrated in certain states, some of which have "warmed 60 times faster than the 10 slowest-warming states."

All of that is according to Climate Central, a research and journalism non-profit that seeks to inform the public about climate and energy. The center looked at data from the National Climatic Data Center's U.S. Historical Climatology Network.

The early reporting of the story had a undeniably alluring narrative: Scientists say dinosaurs passed so much gas, they affected climate enough to cause their demise. That's how Fox News and the Daily Mail, one of the first to move the story, framed this latest research.

Melt Or Grow? Fate Of Himalayan Glaciers Unknown

Originally published on Tue April 24, 2012 8:14 am

The Himalayas are sometimes called the world's "third pole" because they are covered with thousands of glaciers. Water from those glaciers helps feed some of the world's most important rivers, including the Ganges and the Indus. And as those glaciers melt, they will contribute to rising sea levels.

So a lot is at stake in understanding these glaciers and how they will respond in a warming world. Researchers writing in the latest issue of Science magazine make it clear they are still struggling at that task.
