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 Boulder.

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 Boulder 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 Boulder scientists.

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

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.
