Here’s a new recipe that might be good for the planet: Add sunlight to a particular nitrogen molecule and out comes ammonia, the main ingredient of fertilizer used around the world. The eco-friendly method of producing ammonia is described in a new study led by the Department of Energy’s National Renewable Energy Laboratory in Golden and involving CU-Boulder.

CU-Boulder and the National Weather Service (NWS) want your help investigating large surface hail accumulations from thunderstorms in Colorado between April and September.

A new study has found that the number of islands that will become substantially more arid by mid century is 73 percent, up from an estimate of 50 percent.

<p>Rising levels of atmospheric nitrogen pollution threaten plant diversity at nearly one-quarter of sites across a widespread portion of the U.S., according a new study led by University of Colorado Boulder researchers.</p>

Arctic sea ice was at a record low maximum extent for the second straight year, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder and NASA.

<p>Large, severe fires in the West followed by increasing drought conditions as the planet warms are leading to lower tree densities and increased patchiness in high-elevation forests, according to a new study. The researchers found that the rate of post-fire tree seedling establishment decreased substantially with greater post-fire drought severity.</p>

<p>“Upside-down rivers” of warm ocean water threaten the stability of floating ice shelves in Antarctica, according to a new study led by researchers at the University of Colorado Boulder’s National Snow and Ice Data Center. The study highlights how parts of Antarctica’s ice sheet may be weakening due to contact with warm ocean water.</p>

<p>Like an albatross scanning for pods of squid in a vast ocean, molecules on solid surfaces move in an intermittent search pattern that provides maximum efficiency, according to new research from the University of Colorado Boulder.</p>

<p>For the half billion people living on the world’s river deltas and the hundreds of millions of others who rely on them for water, food, shelter, transportation and energy, the news is not good. More than two-thirds of the the world’s 33 major river deltas are sinking and the vast majority have experienced flooding in recent years, primarily a result of human activity.</p>

<p>The newly-exposed edges of deforested areas are highly susceptible to drastic temperature changes, leading to hotter, drier and more variable conditions for the forest that remains, according to new research from the University of Colorado Boulder.</p>
