Does cloud seeding work? Scientists watch ice crystals grow inside clouds to find out

March 14, 2018

Water is a valuable resource that affects nearly all aspects of life on earth. It also is limited, so people use a variety of methods to ensure that supply meets demand.


Climate Change & Health Symposium spotlights CU opportunity to collaborate on emerging global issue

March 13, 2018

Researchers from the University of Colorado Anschutz Medical Campus and the University of Colorado Boulder led a Climate Change and Health Symposium at CU Anschutz on March 12 to explore the imminent challenges and opportunities arising from the nexus of these two interdependent arenas.

I've studied nuclear war for 35 years -- you should be worried.

March 1, 2018

For the first time in decades, it's hard to ignore the threat of nuclear war. But as long as you're far from the blast, you're safe, right? Wrong. In this sobering talk, atmospheric scientist Brian Toon explains how even a small nuclear war could destroy all life on earth -- and what we can do to prevent it.

Does cloud seeding really work? An experiment above Idaho suggests humans can turbocharge snowfall

Jan. 23, 2018

Cloud seeding—sowing clouds with small particles to make them rain or snow—has a reputation as dodgy as the weather. That’s because even though scientists have been seeding clouds since the 1940s, there was precious little proof the technique worked. Now, researchers flying two small planes through a bank of clouds in Idaho have shown, for the first time outside the lab, that humans can artificially turbocharge snowfall.


Cloud seeding for snow: Does it work? Scientists report first quantifiable observations

Jan. 23, 2018

For the first time, scientists have obtained direct, quantifiable observations of cloud seeding for increased snowfall -- from the growth of ice crystals, through the processes that occur in clouds, to the eventual snowfall.

Continued Emissions May Cause Global North-to-South Shift in Wind Power By End of Century

Dec. 14, 2017

In the next century, wind resources may decrease in many regions of the Northern Hemisphere and could sharply increase in some hotspot regions down south, according to a study by University of Colorado Boulder researchers. The first-of-its-kind study predicting how global wind power may shift with climate change appears today in Nature Geoscience.
