An international science team involving the University of Colorado at Â鶹ӰԺ that is working on the North Greenland Eemian Ice Drilling project hit bedrock July 27 after two summers of work, drilling down more than 1.5 miles in an effort to help assess the risks of abrupt future climate change on Earth.

Environmental engineering faculty and students at the University of Colorado at Â鶹ӰԺ are launching a study this month to determine the environmental fate of chemical dispersants being used in the Gulf oil spill cleanup.

Forest fires that have burned thousands of acres near Durango over the last several years may be responsible for unlocking the mercury trapped beneath the soil in the San Juan National Forest and allowing it to wash into Vallecito Reservoir northeast of Durango, according to preliminary findings by a University of Colorado at Â鶹ӰԺ engineering professor.

Newly detected rising sea levels in parts of the Indian Ocean, including the coastlines of the Bay of Bengal, the Arabian Sea, Sri Lanka, Sumatra and Java, appear to be at least partly a result of human-induced increases of atmospheric greenhouse gases, says a study led by the University of Colorado at Â鶹ӰԺ.

A new study shows the Arctic climate system may be more sensitive to greenhouse warming than previously thought, and that current levels of Earth's atmospheric carbon dioxide may be high enough to bring about significant, irreversible shifts in Arctic ecosystems.

To the untrained eye, University of Colorado at Â鶹ӰԺ Research Associate Craig Lee's recent discovery of a 10,000-year-old wooden hunting weapon might look like a small branch that blew off a tree in a windstorm.

A vast ocean likely covered one-third of the surface of Mars some 3.5 billion years ago, according to a new study conducted by University of Colorado at Â鶹ӰԺ scientists.

Five journalists have been selected as 2010-11 Ted Scripps Fellows in Environmental Journalism at the University of Colorado at Â鶹ӰԺ.

A new scientific study packs a double surprise about the chemistry happening in the air around us. Chlorine, a chemical usually kicked into the atmosphere by sea spray, is more abundant than expected in air far from any coastline, and looks to be interacting with manmade pollution at night in ways that might affect air quality and climate.
