Loss of Arctic Sea Ice Speeds Domino Effect of Warming Temperatures at High Latitudes

25.01.2013
Melting Arctic sea ice is no longer just evidence of a rapidly warming planet— it’s also part of the problem.

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.”

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
