Alan Werner, professor of geology at Mount Holyoke College, said that decreasing amounts of Arctic snow and ice in summer will lead to a greater degree of heat absorption at the North Pole.
The reason, Werner said, is because the loss of snow and ice makes the earth’s surface less reflective, meaning solar radiation—or heat—is absorbed in greater amounts by the exposed dark ocean or tundra.
“That’s the thing that’s happening very abruptly, or at least in geologic time scales, very quickly,” Werner said. “That the high latitudes are warming at a much faster rate than the other latitudes.”
Werner’s observation follows the announcement in September by the National Snow and Ice Data Center that the surface area of Arctic sea ice had reached a new low in 2012, breaking a previous record reached in 2007.
What the new data suggests, Werner said, is that the Arctic Ocean will likely be free of sea ice during summer in the next few decades, which may trigger significant changes in climate across the globe.
“One thing about humans living on the planet is that we don’t do well with change,” Werner said. “The changes that we’re talking about are changes that are going to be difficult for humans to adapt to.”

A biological and energy-efficient process, developed and patented by the University of Innsbruck, converts nitrogen compounds in wastewater treatment facilities into harmless atmospheric nitrogen gas. This innovative technology is now being refined and marketed jointly with the United States’ DC Water and Sewer Authority (DC Water). The largest DEMON®-system in a wastewater treatment plant is currently being built in Washington, DC.
The DEMON®-system was developed and patented by the University of Innsbruck 11 years ago. Today this successful technology has been implemented in about 70...
Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.
The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...
In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.
In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
