<p>Three University of Colorado at Boulder programs receive special recognition in the recently released 2011 Fiske Guide to Colleges, including a Top 10 ranking as "environmental studies schools that should be on your radar."</p>

<p>Dark-colored dust that settles on snow in the Upper Colorado River Basin makes the snow melt early and robs the Colorado River of about 5 percent of its water each year, says a new study co-authored by researchers from the University of Colorado at Boulder-based Cooperative Institute for Research in Environmental Sciences, or CIRES.</p>

<p>The Arctic sea ice cover appears to have reached its minimum extent for the year, the third-lowest recorded since satellites began measuring sea ice extent in 1979, according to the University of Colorado at Boulder's National Snow and Ice Data Center.</p>

<p>The University of Colorado at Boulder's Renewable and Sustainable Energy Institute, or RASEI -- a joint venture with the U.S. Department of Energy's National Renewable Energy Laboratory -- will partner with Toyota Motor Sales U.S.A. Inc. in a field study of household experiences and the technical impacts of plug-in hybrid electric vehicles, or PHVs, in a "smart grid" environment.</p>

<p>Faculty at the University of Colorado at Boulder, Montana State University, the University of Idaho and collaborators at the U.S. Forest Service received a $3.85 million grant to study fire and climate change in sensitive forests in the United States, Australia and New Zealand.</p>

<p>Large changes in the sun's energy output may drive unexpectedly dramatic fluctuations in Earth's outer atmosphere, new research indicates. A study published today links a recent, temporary shrinking of a high atmospheric layer with a sharp drop in the sun's ultraviolet radiation levels.</p>

<p>A new study of the High Arctic climate roughly 50 million years ago led by the University of Colorado at Boulder helps to explain how ancient alligators and giant tortoises were able to thrive on Ellesmere Island well above the Arctic Circle, even as they endured six months of darkness each year.</p>

<p>Postdoctoral fellows and graduate students from Professor Mark Hernandez's environmental engineering lab at the University of Colorado at Boulder will travel to the Gulf Coast this week to begin studying the effect of this summer's oil spill on air quality along impacted shores.</p>

<p>A thick blanket of yellow haze hovering over Houston as a result of chemical pollution produced by manufacturing petroleum products may be getting a little bit thinner, according to a new study.</p>

<p>The University of Colorado at Boulder and the U.S. Department of Energy's National Renewable Energy Laboratory in Golden today named Michael L. Knotek as director of the Renewable and Sustainable Energy Institute, or RASEI.</p>
