Fiber-optic cables like the ones that bring television and Internet into millions of homes are now being used to measure how fast ice shelves in Antarctica are melting, according to new research.
Researchers installed moorings containing fiber-optic cables hundreds of meters down into the McMurdo Ice Shelf in West Antarctica to collect temperature information about the base of the ice shelf, where the thick platform of floating ice meets the ocean. The sensors were able to measure mere millimeters of ice loss at the interface, demonstrating that the new fiber-optic method could be used to remotely monitor the ice shelves in real-time.
Data on the melting rates of ice shelves provides scientists with critical information on the stability of the Antarctic ice sheets and sea level rise.
GeoSpace spoke with Scott Tyler, a hydrologist at the University of Nevada, Reno and the study’s principal investigator, about the new research that has been accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union.

A new New York Times poll finds that most Americans think protecting the environment from climate change, and over half say it is caused by human behavior, “the highest level ever recorded by the national poll.”

Wind power capacity per capita in Europe
The European Wind Energy Association - EWEA might be able to tell you more about wind power in Europe.
EWEA is the voice of the wind energy industry, actively promoting wind power in Europe and worldwide. It has over 700 members from almost 60 countries

It is the southwest part of the Wadden Sea. The thin white line is the Afsluitdijk.
The Wadden Sea (Dutch: Waddenzee, German: Wattenmeer, Low German: Wattensee or Waddenzee, Danish: Vadehavet, West Frisian: Waadsee) is an intertidal zone in the southeastern part of the North Sea. It lies between the coast of northwestern continental Europe and the range of Frisian Islands, forming a shallow body of water with tidal flats and wetlands. It is rich in biological diversity. In 2009, the Dutch and German parts of the Wadden Sea were inscribed on UNESCO’s World Heritage List and the Danish part was added in June 2014.
According to C. Michael Hogan, the Wadden Sea is one of the world’s seas whose coastline has been most modified by humans, via systems of dikes and causeways on the mainland and low lying coastal islands. The Wadden Sea stretches from Den Helder in the Netherlands in the southwest, past the great river estuaries of Germany to its northern boundary at Skallingen north of Esbjerg in Denmark along a total length of some 500 km and a total area of about 10,000 km². Within the Netherlands it is bounded from the IJsselmeer by the Afsluitdijk.
The islands in the Wadden Sea are called the Wadden Sea Islands or Frisian Islands, named after the Frisians. However, on the westernmost Dutch island, Texel, the Frisian language has not been spoken for centuries. The Danish Wadden Sea Islands have never been inhabited by Frisians. The outlying German island of Helgoland, although ethnically one of the Frisian Islands, is not situated in the Wadden Sea.
The German part of the Wadden Sea was the setting for the 1903 Erskine Childers novel The Riddle of the Sands.
I took my thermal camera to Yellowstone, because I’m just that much of a nerd.

5: Firehole River at Midway Geyser Basin. The left side of the river is notably warmer than the right because of the Excelsior Geyser outflow just upstream.
7: Hot Pool Runoff Channels
9: Heat traces underneath the Firehole Lake parking lot. It was a cold, overcast day. A parking lot surface should not have been 40C. This points to something interesting going on under the surface. (It should be noted that this is not the section of Firehole Lake Drive that melted earlier this year…)
10: Temperature gradient at Whirligig Geyser in Norris Geyser Basin. Here, the runoff from two pools joins into a single stream. The green thermophile likes the cooler water on the left side, while the right side is hotter.
