Berkeley Lab research could lead to a better understanding of the Arctic ecosystem’s impact on the planet’s climate

What does pulling a radar-equipped sled across the Arctic tundra have to do with improving our understanding of climate change? It’s part of a new way to explore the little-known world of permafrost soils, which store almost as much carbon as the rest of the world’s soils and about twice as much as is in the atmosphere.

The new approach combines several remote-sensing tools to study the Arctic landscape—above and below ground—in high resolution and over large spatial scales. It was developed by a group of researchers that includes scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). (more…)

Time Running Out to Save Climate Record Held in Unique Eastern European Alps Glacier

COLUMBUS, Ohio – A preliminary look at an ice field atop the highest mountain in the eastern European Alps suggests that the glacier may hold records of ancient climate extending back as much as a thousand years.

Researchers warn, however, that the record may soon be lost as global warming takes its toll on these high-altitude sites, according to a new study in the Journal of Glaciology.

The glacier, Alto dell’Ortles, is the highest large ice body in the eastern Alps, reaching an altitude of 12,812 feet (3,905 meters) above sea level. It is small, though, measuring barely 0.4 square miles (1.04 square kilometers), and only 10 percent of that is likely to hold a good climate record, the researchers said. (more…)
