Under drought conditions, tropical forests can be as efficient at using water as desert ecosystems, a finding that has implications for how various ecosystems will behave under future climate change.
Gregg Garfin of UA's CLIMAS project joins with other climate scientists and fire experts to brief the media on the forecast for this year's wildfire season in the western United States and Alaska.
Recent winter storms have brought some relief and bought some time, but experts expect another long, hot summer.
Guess why oceanographers are interested in Saturn's moon Titan.
Longtime hydrology Professor Sol Resnick, an internationally respected authority on arid and semi-arid lands, will be feted at a Nov. 18 ceremony at the WRRC.
Drought as striking as the recent drought in Arizona and New Mexico is unusual but not unknown, conclude UA tree-ring scientists who have reconstructed a thousand-year history of winter precipitation in the American Southwest.
The drought that has reduced Lake Powell to half of its full pool capacity also has exposed the 30-mile length of the upper Colorado River delta, and that delta is eroding rapidly into Lake Powell toward Glen Canyon Dam.
UA hydrologists have recently developed data-gathering and computer-imaging technologies that allow them to create three-dimensional images that accurately show where water is most likely to flow through an underground site.
Winter and spring snowfall are vitally important to the West's water resources. So researchers are developing computer models to more accurately predict snowfall.
As the ocean current called El Nino strengthened this past summer, it raised hopes that a 5-year drought gripping the U.S. Southwest might break this spring with plentiful rains. But if the rains do materialize, they may offer only temporary respite, according scientists who've looked at 750-year-long tree-ring records across the Rocky Mountain region.
