Chris Guiterman - 2014 CLIMAS Climate & Society Graduate Fellow

Thursday, March 12, 2015

From the very beginning, Chris Guiterman just wanted an opportunity to expand his collaboration with the Navajo Forestry Department, and to demonstrate what he could do to help them. 

Guiterman is a 2014 recipient of the Climate Assessment for the Southwest (CLIMAS) Climate & Society Graduate Fellows Program. He is currently a PhD student at the University of Arizona, School of Natural Resources and the Environment, working in the Laboratory of Tree-Ring Research.

He used the CLIMAS fellowship to jumpstart a project that he had been struggling to fund.

Tribal nations across the Southwest are increasingly at risk of climate change impacts on the landscape, and because many of these nations rely on the ecosystem services of healthy forests, the risks are intensified. 

“Tasked with managing over 5 million acres of forests and woodlands, the Navajo Forestry Department has identified the need to assess sensitivities of their forests to drought and climate change,” according to the abstract of Guiterman’s research project. Guiterman worked with the NFD foresters to address their needs by quantifying the climatic drivers of forest growth in the Chuska Mountains. (read more)

Rebecca Lybrand - 2014 CLIMAS Climate & Society Graduate Fellow

Wednesday, March 11, 2015

To Rebecca Lybrand, calling soil “dirt” is simplistic and diminishes its importance to plants, animals, and human beings.  So why is soil, the foundation of life, constantly being referred to as “dirt?”  Rebecca began this line of thinking in college, and this spark of curiosity turned a simple question into a career. 

Rebecca is now a soil scientist at The University of Arizona.  She received her Ph.D. from The University of Arizona’s Department of Soil, Water and Environmental Science (SWES) in 2014. She is also a recipient of the 2014 Climate Assessment for the Southwest (CLIMAS) Climate & Society Graduate Fellowship. 

Rebecca’s CLIMAS project centered on creating two short films that documented her research across the Santa Catalina Mountains in Arizona. These films showcase four of her field sites, which span over 4000 feet of elevation gain. The sites differ in temperature, precipitation, and vegetation, all of which have remarkable impacts on the characteristics of these soils. 

The visuals for both films are the same, but the scripts change to present the science message in two different contexts. One uses a lively, first person perspective that relays a scientific story, using Rebecca’s personal experience to frame the film.  The other is in third person, and presents a formal video delivering a more scientific message along the lines of what you might see in a science documentary. The main objective of this project is to survey students and to evaluate the effectiveness of formal and informal communication techniques. (read more)

Ling-Yee Huang - 2014 CLIMAS Climate & Society Graduate Fellow

Tuesday, March 10, 2015

When Ling-Yee Huang received the Climate Assessment for the Southwest (CLIMAS) Climate & Society Graduate Fellowship a year ago, she proposed to create a climate science curriculum for law schools.  Little did she know, she would actually be teaching her own class on climate science curriculum for lawyers, at the James A. College of Law at The University of Arizona.

Huang is currently a M.S. student in the School of Natural Resources and the Environment (SNRE) at the University of Arizona, as well as a researcher at the Water Resources Research Center (WRRC).  Previously, she earned a J.D. from the University of Florida Levin College of Law and a bachelor’s degree in biology from Rice University.

Before coming to UA, Huang worked as a policy analyst for the Center for Progressive Reform in Washington, D.C.  She provided legal analysis regarding the Clean Water Act and restoration of the Chesapeake Bay, and she developed legal frameworks for climate change adaptation and protecting ecosystem services.

“I have always really liked the idea of combining science and decision making,” said Huang.  “I started grad school having worked in the decision and policy making field for a couple of years and in that experience I felt that there was a real lack of understanding of science.”

Huang said when she learned about the CLIMAS fellowship, she realized it captured her dual interests in both science and policy perfectly. The curriculum and her final project were ideas she had been contemplating for a long time. 

“I found it the perfect fit,” said Huang. (read more)

Sarah Truebe - 2014 CLIMAS Climate & Society Graduate Fellow

Monday, March 9, 2015

Sarah Truebe has always been a caver.  She grew up thinking the only things people should take from caves are photographs, but as she began her career as a paleoclimate scientist, she realized that scientists often take a lot more than photographs.

A stalagmite is a cylindrical mineral deposit, formed over hundreds or thousands of years on the floor of a cave, making them utterly non-renewable on human timescales.  Stalagmites contain valuable paleoclimate data; however, most of the time getting this information means permanently removing the stalagmite from the cave. 

“As the popularity of stalagmite paleoclimate science grows, development of sustainable sampling methods for these nonrenewable resources is necessary to balance the needs of science and cave conservation,” Truebe said. 

Truebe is a PhD candidate in the Department of Geosciences at the University of Arizona and is also a 2014 recipient of the Climate Assessment for the Southwest (CLIMAS) Climate & Society Graduate Fellows Program. She used this opportunity to collect information on different stalagmite sampling methods, with the intention of developing best practice recommendations for extraction. (read more)

El Niño Tracker - Southwest Climate Outlook February 2015

Friday, February 20, 2015

Originally published in the Feb 2015 CLIMAS Southwest Climate Outlook

A definitive 2014–2015 El Niño forecast remains elusive. Weak El Niño conditions have continued in 2015, but recent backsliding in SST anomalies (Fig. 1), especially in the Niño 1-2 regions (Fig. 2), along with the ongoing lack of coordination between atmospheric and oceanic conditions, give little confidence that the 2014–2015 event will be characterized as anything more than a weak El Niño.

2015 CLIMAS Climate & Society Graduate Fellows

Thursday, February 12, 2015

The Climate & Society Graduate Fellows Program supports University of Arizona graduate students whose work connects climate research and decision making. Fellows receive $5,000 and guidance from members of the CLIMAS research team (Climate Assessment for the Southwest) for one year. The program’s main objective is to train a group of students to cross the traditional boundaries of academic research into use-inspired science and applied research. While CLIMAS research generally occurs in the Southwest U.S., the Fellows program allows students to work anywhere in the world. (read more)

El Niño Tracker - January 2015

Friday, January 23, 2015

Just when it looked like we were getting a more definitive answer regarding El Niño, ongoing lack of cooperation on the part of the atmosphere continues to muddy forecasts moving into 2015. Sea surface temperatures (SSTs) remain elevated across much of the equatorial Pacific Ocean (Fig. 1), and while temperature anomalies in the Niño 3.4 region are within the range of a weak El Niño event, they have declined in the past month (Fig. 2). It is a common refrain in forecast bulletins that a lack of coupling between ocean and atmosphere is responsible for decreased confidence in an El Niño event this winter. Additionally, a lack of temperature gradient along the equatorial Pacific and little in the way of El Niño wind patterns further reduce confidence that a stronger event is on the horizon.

Recap: Drought and Water Supplies in the Southwest - 1075' Shortage on the Colorado River

Wednesday, August 13, 2014

This week, we released the 5th episode in the CLIMAS podcast series[1] 1075' - Shortage on the Colorado River, which explores what a shortage declaration on the Colorado River would mean to those living in the Southwest.  In this post - Ben McMahan recaps some of the key issues that formed the impetus for this podcast series, summarizes the podcast episodes, and gives some backstory from folks who have been writing about the Colorado River (Basins) for years (read more)

Arizona Facing High Fire Danger a Year After Yarnell

Tuesday, July 1, 2014

It was one year ago that lightning struck and ignited the Yarnell Hill Fire, a devastating wildfire that resulted in the deaths of 19 firefighters who were members of the Granite Mountain Hotshots. This year, a combination of drought conditions, high winds and high temperatures all call for an intense fire season. Predictions indicate above-normal fire potential, and indicators suggest the onset of the monsoon season will be delayed.

Since October, we've had very low precipitation – averaging less than half of average across large portions of the state – accompanied by low snowpack and temperatures that have been well above average.

The combination of these factors, along with bursts of dry winds that are typical for the spring, gives us conditions of above-normal fire potential, which is what the Southwest Coordination Center, the main fire prediction center for our region, predicted beginning in late January.  (read more)
