Robert Pollin and Noam Chomsky share their insights about the upcoming global climate summit and what must ultimately be done to save humanity and the planet from a global climate catastrophe.

The ranking is a recognition of UArizona's Large Scale Renewable Energy agreement with Tucson Electric Power Co. to significantly reduce the university's carbon footprint.

In the face of climate change and persistent droughts, a growing number of people from Zuni Pueblo in New Mexico and elsewhere are adopting the traditional farming practice.

The discovery shifts researchers' understanding of the relationship between the Olmec civilization and the subsequent Maya civilization.

Across the Southwest, thousands of male brown tarantulas are marching across the landscape, their journey part of an annual migration of sorts, when the hairy creatures leave their burrows in search of a mate.

Slower ocean circulation as the result of climate change could intensify extreme cold weather in the U.S., according to new UArizona research.

Studying and measuring food insecurity in the United States was as important as ever during the onset of the COVID-19 pandemic. The National Food Access and COVID Research Team was part of the effort to understand how the pandemic was affecting people to help inform governmental policies. Anna Josephson, assistant professor at the University of Arizona Department of Agricultural and Resource Economics, was part of this team to help accomplish this objective for the state of Arizona.

These summer rainfalls have been vital to the U.S. Southwest ecosystem, but their unpredictability is growing.

Surprisingly little is known about how rain moves through landscapes once it's on the ground. UArizona's Landscape Evolution Observatory is designed to provide answers. A $3.5 million grant will allow scientists to study the roles plants and microbes play in the process.
