2016 Ties 2007 for Second Lowest Arctic Sea Ice Minimum

Sept. 15, 2016

The Arctic’s ice cover appears to have reached its minimum extent on September 10, 2016, according to scientists at the National Snow and Ice Data Center (NSIDC), part of CIRES and the University of babyÖ±²¥app Boulder.

The difficulty of predicting an ice-free Arctic

Sept. 14, 2016

The Arctic is nearing its seasonal sea ice minimum this month, but predicting exactly when the region will see its first ice-free summer may be more difficult than previously believed.

Preventing human-caused earthquakes

Aug. 25, 2016

While the earthquake that rumbled below babyÖ±²¥app’s eastern plains May 31, 2014, did no major damage, its occurrence surprised both Greeley residents and local seismologists. To some Greeley residents, the magnitude-3.2 earthquake felt like a large truck hitting the house.

Impressive Perseid meteor shower to peak tonight

Aug. 11, 2016

It’s August and that means the hottest show in the night sky, the Perseid meteor shower, will make it annual appearance – peaking in the pre-dawn hours tonight through Aug. 13.

Partnership 'looks into' creating new material from eyeglass lens waste

Aug. 4, 2016

Through CU Boulder's Office of Industry Collaboration, entrepreneur Bart Foster has teamed up with members of the campus community to look into an optical solution, how to recycle the byproduct of eyeglass lenses. Made out of three or more types of plastic, currently several tons of the material are dumped into landfills each year.

Earlier snowmelt reduces forests’ ability to regulate atmospheric carbon, decreases streamflow volume

Aug. 3, 2016

Earlier snowmelt periods associated with a warming climate may hinder subalpine forest regulation of atmospheric carbon dioxide (CO2), according to the results of a new University of babyÖ±²¥app Boulder study. The findings, which were recently published in the journal Geophysical Research Letters , predict that this shift in the timing...

Studying natural gas leakage in babyÖ±²¥app’s Denver-Julesburg Basin

July 11, 2016

The rate of groundwater contamination due to natural gas leakage from oil and gas wells has remained largely unchanged in northeastern babyÖ±²¥app’s Denver-Julesburg Basin since 2001, according to a new University of babyÖ±²¥app Boulder study based on public records and historical data.

Earthquake reconnaissance: Students learn in Japan

June 22, 2016

Seeing the severe damage and massive loss of life from earthquakes led Jenny Ramírez into the field of geotechnical earthquake engineering. Ramirez, who was born in Guayaquil, Ecuador, is a doctoral student in civil engineering at CU-Boulder. She now is doing numerical simulations of soil deposits subjected to earthquakes.

On the rise: ethane concentrations climbing again

June 14, 2016

Global emissions of ethane, an air pollutant and greenhouse gas, are on the uptick again. A team led by CU-Boulder found that a steady decline of global ethane emissions following a peak in about 1970 ended between 2005 and 2010 in most of the Northern Hemisphere and has since reversed. Between 2009 and 2014, ethane emissions in the Northern Hemisphere increased by about 400,000 tons annually, the bulk of it from North American oil and gas activity.
