El Niños effects on a Pacific Northwest river valley offer forecasters a window to dry years ahead
PARCHED--Water officials keep tabs on snowpack and reservoir levels to help them forecast drought, this for the Yakima River Valley, mid-February 2005. If this snowpack picture holds up, reservoirs will be depleted and farmers in many water districts can expect irrigation sources to run dry this summer. As climate in the region changes, this forecast will become more and more common, with severe consequences for those who do not plan.

Global warming conversations have shifted from whether climate is changing to how we will deal with the inevitable consequences. And the price you pay will depend on where you live and how well you prepare, suggests one of the most detailed studies to date on global warming and its likely effect on human activity.
"Like politics, global climate change is local," said Michael J. Scott, a staff scientist at the Department of Energys Pacific Northwest National Laboratory in Richland, Wash. "Our behavior where we live must change with the climate if we are to stave off economic and natural catastrophemeet the challenge Mother Nature may hand us in the next few years."

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...

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...
