News

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.

UA geosciences professor Connie Woodhouse co-authored a 2010 study using regional tree rings from an unusually long and hot medieval drought to project that each increase of a degree Celsius results in a decrease in Colorado River flows of between 2 percent and 8 percent. The medieval drought, in its worst decade, baked the river down to about two-thirds of what the U.S. and Mexico draw out of it today. The drought lasted 60 years, but it was not as hot as today. So it seems that the next time, the river will be even drier.

Following national trends, greenhouse gas emissions linked to climate change continue to drop in metro Tucson, a government report shows. The region's weak economy clearly is playing a role in the decline, according to the UA's Derek Lemoine, an assistant professor who specializes in energy and environmental economics. Recent signs of a shift to solar energy and to natural gas from coal burning for electricity also have made a difference.

On the Colorado River's Upper Basin, snowpack levels on Feb. 1 were only 79 percent of normal, down from 100 percent of normal on Jan. 1. In some parts of the West, there has been good precipitation. But because of unusually warm weather, it has fallen as rain instead of snow, hurting the snowpack that feeds California's rivers and reservoirs, said the UA's Michael Crimmins, a specialist in soil, water and environmental science.

There are rules and principles that govern evolution, said Brian Enquist, the UA professor of ecology and evolutionary biology who gave Monday's lecture in the UA's "Life in the Universe" series. Enquist proposed an either/or choice to the audience in his title, "Life on Earth: By Chance or by Law?" Did the path of evolution arise from "multiple events that are essentially unpredictable" or is life "organized by a set of general rules and principles"? Enquist said evolution followed the rules, interrupted by chance historical happenings such as five mass extinctions.
