An international team led by glaciologists from the University of Colorado Boulder and Trent University in Ontario, Canada has completed the first mapping of virtually all of the world’s glaciers — including their locations and sizes — allowing for calculations of their volumes and ongoing contributions to global sea rise as the world warms. The […]
Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new research results. The study shows that Americans face the risk of a 70 percent increase in unhealthy summertime ozone levels by 2050. The results appear online this week in a paper in the Journal […]
The rise and fall of acid rain is a global experiment whose results are preserved in the geologic record. By analyzing samples from the Greenland ice sheet, University of Washington atmospheric scientists found clear evidence of the U.S. Clean Air Act. They also discovered a link between air acidity and how nitrogen is preserved in […]
Scientists are facing a number of barriers as they try to develop circuits that are microscopic in size, including how to reliably control the current that flows through a circuit that is the width of a single molecule. Alexander Shestopalov, an assistant professor of chemical engineering at the University of Rochester, has done just that, […]
