New research from a team of NOAA-led scientists proposes a totally new approach to understanding how tiny particles in the atmosphere and clouds interact—and that understanding those interactions is critical if you want to know how clouds in turn impact climate.
The United States could slash greenhouse gas emissions from power production by up to 78 percent below 1990 levels within 15 years while meeting increased demand, according to a new study by NOAA and University of Colorado Boulder researchers.
University of Colorado Boulder researchers who have spent thousands of hours observing the atmosphere high above Antarctica have discovered a previously unknown class of wave that ripples constantly through the atmosphere, likely affecting high-level winds, climate, and even Earth-based communications systems.
CIRES scientists are lead authors and co-authors on dozens of papers being presented at the annual meeting of the American Meteorological Society meeting in New Orleans, Louisiana this week. Linked are a few highlights, by day.
A new study of snow and firn layers high on the Greenland ice sheet, published in Nature Climate Change, shows that recent atmospheric warming is changing the ability of near-surface firn layers to store meltwater, which can result in a faster release of runoff from the ice sheet.
With the 2015 Paris climate conference underway, we reached out to CIRES Fellow Max Boykoff (Center for Science and Technology Policy Research and CU-Boulder Environmental Studies Program), to learn about the mood at the conference and in Paris.
Something is producing a diffuse, barely perceptible “ice haze” that is whitening global cloud-free skies and changing the way that solar radiation reaches Earth’s surface. A provocative new analysis presented at an international meeting this week points to one likely cause. The work suggests people are already conducting an unintentional geoengineering experiment.
The NOAA Climate Change Portal, developed by ESRL’s Physical Sciences Division (PSD) and CIRES, allows researchers to access and display the large volumes of climate and earth system models used by the Intergovernmental Panel on Climate Change (IPCC) for the Fifth Assessment Report.
Clouds can increase warming in the changing Arctic region more than scientists expected, by delivering an unexpected double-whammy to the climate system, according to a new study by researchers at NOAA, the University of Colorado Boulder and colleagues.
