Environmental variability and global change are discussed more and more frequently in news articles and programs as the general public becomes increasingly aware of the rapid environmental transformations taking place around the world. The Institute of the Environment produces general interest articles about current UA research relevant to the environment, spotlights that chronicle the work of IoE faculty, and other articles, including a series on drought in the Southwest. The most recent articles are listed below. Older articles and links to UA News press releases also are available in the News Archive.

About 98 percent of California continues to remain at some level of drought, and it will take an inordinate amount of precipitation to change that. UA scientist Valerie Trouet emphasized that "the increasing temperatures in recent years have contributed" to the drought's extreme nature. It's a problem, added the UA's Jonathan Overpeck, that's only going to become more intense as climate change worsens. Temperature "has a big role to play in droughts of the past and will probably have a bigger role in droughts in the future, making them more severe," Overpeck said.

California and Arizona will likely see 2014 go down as their warmest years on record, reflecting high temperatures that dry out soils and melt snowpack faster than a drought would by itself. "If this winter proves drier than usual" for either California or the greater Southwest, said Jonathan Overpeck, director of the UA's Institute of the Environment, "then expect much greater pain and recognition of the role that climate change is playing in drying out critical portions of our nation."

Gregg Garfin, a UA climate scientist, said 2014's record warm temperature in Tucson, which matched the global record warm temperature for the past year, "certainly seems consistent" with projections that UA scientists and others have made for future global warming. Four of Tucson's six warmest years on record, including 2014, have occurred in the past six years.

In an op-ed piece, Sharon Megdal, director of the UA's Water Resources Research Center, discusses Arizona's water-use options in light of a challenging future.

New research reveals coral shows signs of global warming, providing a clear visual record of climate change. Researchers from the UA and the National Center for Atmospheric Research examined chemical changes in coral, allowing investigators to read a record of trade winds in the Pacific Ocean. The finding supports the theory that strong Pacific trade winds are helping prevent global temperatures from climbing.

A burst of new water last spring transformed the Colorado River Delta from a mud flat into a budding greenbelt. Photos, satellite images and monitoring equipment show more and greener plants, and a higher water table, because of the artificial spring 2014 release of water into the river at the Mexican border south of Yuma. The results of the delta "pulse flow" were released Wednesday at a briefing featuring UA scientist Karl Flessa and two Tucson-based federal scientists.
