<p>A new University of Colorado Boulder-led study that ties forest “greenness” in the western United States to fluctuating year-to-year snowpack indicates mid-elevation mountain ecosystems are most sensitive to rising temperatures and changes in precipitation and snowmelt.</p>

<p>The National Oceanic and Atmospheric Administration has selected the University of Colorado Boulder to continue a federal/academic partnership that extends NOAA’s ability to study climate change, improve weather models and better predict how solar storms can disrupt communication and navigation technologies.</p>
<p><span id="">The selection means that NOAA will continue funding the Cooperative Institute for Research in Environmental Sciences, or CIRES, for at least five years and up to 10 more years. CIRES was established at CU-Boulder in 1967.</span></p>

<p>An international research team led by the University of Colorado Boulder and the University of Helsinki has discovered a surprising new chemical compound in Earth’s atmosphere that reacts with sulfur dioxide to form sulfuric acid, which is known to have significant impacts on climate and health.</p>

<p>Despite sharp increases in carbon dioxide emissions by humans in recent decades that are warming the planet, Earth’s vegetation and oceans continue to soak up about half of them, according to a surprising new study led by the University of Colorado Boulder.</p>

<p>A variety of public health issues plague the refugees from Burma living on the Thai border, not the least of which is drinking water contaminated by bacteria and pesticides. Yet few low-cost, sustainable and appropriate treatment technologies are available to people in rural and developing communities to ensure water safety.</p>

A new study led by the University of Colorado Boulder indicates air pollution in the form of nitrogen compounds emanating from power plants, automobiles and agriculture is changing the alpine vegetation in Rocky Mountain National Park.

<p>The California condor is chronically endangered by lead exposure from ammunition and requires ongoing human intervention for population stability and growth, according to a new study led by the University of California, Santa Cruz, and involving the University of Colorado Boulder. </p>
