A new study by an international team of scientists analyzing ice cores from the Greenland ice sheet going back in time more than 100,000 years indicates the last interglacial period may be a good analog for where the planet is headed in terms of increasing greenhouse gases and rising temperatures.

When a sun-gazing NASA satellite designed and built by the University of Colorado Boulder launched into space on Jan. 25, 2003, solar storms were raging.

A new NASA-led study involving the University of Colorado Boulder finds that when it comes to combating global warming caused by emissions of ozone-forming chemicals, location matters. Ozone is both a major air pollutant with known adverse health effects and a greenhouse gas that traps heat from escaping Earth鈥檚 atmosphere. Scientists and policy analysts are interested in learning how curbing the emissions of ozone-forming chemicals can improve human health and also help mitigate climate change.

To reflect its broader focus, the Colorado Renewable Energy Collaboratory, a research consortium including the University of Colorado Boulder, the Colorado School of Mines, Colorado State University and the U.S. Department of Energy鈥檚 National Renewable Energy Laboratory has adopted a new name: the Colorado Energy Research Collaboratory.

Gaping crevasses that penetrate upward from the bottom of the largest remaining ice shelf on the Antarctic Peninsula make it more susceptible to collapse, according to University of Colorado Boulder researchers who spent the last four Southern Hemisphere summers studying the massive floating sheet of ice that covers an area twice the size of Massachusetts.

A team led by the University of Colorado Boulder has been awarded $9.2 million over five years from the U.S. Department of Energy to research modifying E. coli to produce biofuels such as gasoline. 鈥淭his is a fantastic opportunity to take what we have worked on for the past decade to the next level,鈥� said team leader Ryan Gill, a fellow of CU-Boulder鈥檚 Renewable and Sustainable Energy Institute, or RASEI. 鈥淚n this project, we will develop technologies that are orders of magnitude beyond where we are currently.鈥�

An analysis of mineral grains from the bottom of the western Grand Canyon indicates it was largely carved out by about 70 million years ago -- a time when dinosaurs were around and may have even peeked over the rim, says a study led by the University of Colorado Boulder.

The wild and dramatic cascade of ice into the ocean from Alaska鈥檚 Columbia Glacier, an iconic glacier featured in the documentary 鈥淐hasing Ice鈥� and one of the fastest moving glaciers in the world, will cease around 2020, according to a study by the University of Colorado Boulder.

A $20 million remote sensing instrument package built by the University of Colorado Boulder, which is leading a 2013 NASA mission to understand how Mars might have lost its atmosphere, has been delivered to Lockheed Martin in Littleton, Colo., for spacecraft integration.
