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.
In this undated picture, Mount Everest, the world's tallest mountain at 29,029 feet, stands behind the Khumbu Glacier, one of the longest glaciers in the world. Nepal has more than 2,300 glacial lakes, and experts say at least 20 are in danger of bursting.
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.

Most Americans believe that global warming has played a role in a series of unusual weather events during the past year.
A poll released today by the Yale Project on Climate Change Communication and the George Mason University Center for Climate Change Communication found that 72 percent of Americas believe global warming played a role in the very warm winter the United States just experienced.
