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.”

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
