A large-scale research project at the University of Alaska Fairbanks Geophysical Institute has revealed insight into the relationship between surface debris on glaciers and the rate at which they melt.
The work is the first global assessment of Earth s 92,033 debris-covered glaciers and shows that debris, taken as a whole, substantially reduces glacier mass loss.
The results will affect sea level rise calculations and allow for improved assessment of hazards faced by nearby communities. This is the first step to enable us to start projecting how these debris-covered glaciers are going to evolve in the future and how they re going to affect glacial runoff and sea level rise, said glaciologist David Rounce, the lead author of a paper published April 28 in

NASA s Hubble Space Telescope made this close-up view of an electric-blue aurora that is eerily glowing one half billion miles away on the giant planet Jupiter in 2010.
Jupiter’s auroras are the most powerful in the solar system. What’s puzzling is, despite the magnitudes of these potentials at Jupiter, they are observed only sometimes and are not the source of the most intense auroras, as they are on Earth.
At Jupiter, the brightest auroras are caused by some turbulent acceleration process that remains poorly understood.
Peter Delamere, a professor of space physics at the University of Alaska Fairbanks Geophysical Institute, is among an international team of 13 researchers who have made a fundamental discovery related to the aurora of our solar system‘s most giant planet.
