Answering a longstanding question: Why is the surface of ice wet?

Answering a longstanding question: Why is the surface of ice wet? Sapporo, Japan (SPX) Nov 22, 2016 - A team of Hokkaido University scientists has unraveled a 150-year-old mystery surrounding the surface melting of ice crystals in subzero environments by using an advanced optical microscope. "Ice is wet on its surface": Since this phenomenon, called surface melting, was mentioned by British scientist Michael Faraday more than 150 years ago, the question of why water on the surface of ice d ... more

Enhanced nitrous oxide emissions found in Arctic Joensuu, Finland (SPX) Nov 22, 2016 - The Arctic is warming rapidly, with projected temperature increases larger than anywhere else in the world. The Arctic regions are particularly important with respect to climate change, as permafrost soils store huge amounts of the Earth's soil carbon (C) and nitrogen (N).
