Southwest Climate Podcast: Monsoon Mechanics and Wildfire

Monday, July 1, 2013

The monsoon is here! In the July Southwest Climate Podcast, Zack Guido, Mike Crimmins, and guest speaker J.J. Brost from the National Weather Service discuss the mechanics behind the monsoon, what we can expect from the rest of the season, and the mechanics behind fires starting at the beginning of the monsoon, such as the Yarnell fire near Prescott.

Recent Variations in Low-Temperature and Moisture Constraints on Vegetation in the Southwestern U.S.

Friday, April 19, 2013

Dr. Jeremy Weiss, a senior researcher with UA’s Environmental Studies Laboratory, will discuss the importance of seasonality and elevational gradients for understanding the effects of drought and warming on vegetation in topographically complex regions like the Southwest, and explain how projected changes in future regional climate may potentially further or alter these effects.

Field of Dreams, or Dream Team? Assessing Two Models for Drought Impact Reporting in the Semiarid Southwest

Friday, March 22, 2013

To make decisions about drought declarations, status, and relief funds, decision makers need high quality local-level drought impact data. In response to this need in Arizona, the Arizona DroughtWatch program was created, which includes an online drought impacts reporting system. Despite extensive and intensive collaboration and consultation with the intended public participants, Arizona DroughtWatch has had few consistent users and has failed to live up to its goal of providing decision makers or the public with high quality drought impacts data.

Drought Impacts on Dust and Health in New Mexico

Friday, March 1, 2013

Dust storms create both health issues and transportation hazards. Valley Fever is endemic to the border region and gets carried with the dust. Interstates and local highways are often closed for hours in an attempt to avoid accidents and injuries. Windblown dust concentrations can be very high when strong winds occur during extended droughts - creating “exceptional episodes” of poor air quality. Air quality in rural areas of New Mexico and along the US/Mexico border is normally acceptable and well below the US EPA’s air quality standards for particulate matter. But these episodes expose millions of people to particulate levels that exceed air quality standards. (read more)

Key Findings from the Assessment of Climate Change in the Southwest

Friday, February 8, 2013

Gregg Garfin, lead-coordinating author of this report, will present these and other key findings on Friday, Jan. 25th at 10:30 am in Marshall 531. The report drew on contributions from 121 authors and will be published in early 2013. You can currently access the first chapter of the report, known as the Summary for Decision Makers. The full report will be available here.

The Assessment of Climate Change in the Southwest United States is one of eight regional technical contributions to the National Climate Assessment, which will summarize key findings from each region and will help inform informs the nation about observed changes and anticipated climate trends.  The National Climate Assessment report will be published later this year.

Southwest Climate Podcast: Arizona "Blizzard" - Drought Remedy?

Friday, February 1, 2013

Was the "blizzard" in February unprecedented for Arizona, and did climate change play any role? In this month's podcast, Gregg Garfin and Zack Guido discuss this and the influence the storm and recent temperatures had on the state's snowpack. They also explore the status of drought in both Arizona and New Mexico, and what the precipitation forecast looks like for the next few months.
