Winter outdoor recreation opportunities in Utah are directly impacted by the effects of climate change and deteriorating air quality. We examine the influences of daily weather conditions and air quality on winter use of two prominent Utah canyons located just outside Salt Lake City-Big and Little Cottonwood Canyons. Daily weather data were collected both within the canyons and in Salt Lake City; daily air quality data were collected for just Salt Lake City. We hypothesized that desirable weather within the canyons (i.e., cooler temperatures, more snowfall, and deeper snow depths) serves as a “pull” factor, positively influencing the volume of traffic. We also hypothesized that poor air quality within the city acts as a “push” factor on individuals’ travel behavior, this too would positively influence the volume of traffic up the canyons. We used a panel time-series regression model to determine the influence of both these “push” and “pull” factors on use of the canyons during the winter months. Our results revealed that, as expected, cooler temperatures and greater amounts of snow in the canyons, as well as poorer air quality in the city, have a positive and significant influence on winter canyon use. These findings suggest that warmer winter temperatures, as well as deteriorating air quality in the city, may have substantial impacts on Utah’s outdoor recreation economy.

Subject Material

A survey of 396 undergraduate and graduate students from 51 countries on 5 continents currently enrolled in Forestry or Related Natural Resource (FRNR) degree programmes was conducted of attendees to the International Union of Forest Research Organizations' (IUFRO) conference in Salt Lake City, Utah, 2014. These perspectives come from some of the most active students in their respective fields. We explored the motivating reasons for enrolling in their current FRNR programme, and conversely why they may have been hesitant to do so. Results indicate that enjoyment of nature was the most important factor on average driving the decision to enroll, closely followed by job satisfaction, concern for the environment, enjoyment of outdoor recreation, being outdoors, and an interest in subject material. Hesitancy factors included earning potential, availability of funding/scholarships, and politically contentious issues. A number of significant differences were found across demographic categories. Of particular note was the greater hesitancy on the part of women and people of color to enroll in FRNR degree programmes compared to their white male counterparts. We discuss the limitations of our study arising from its international scope and imbalance of responses among countries and regions.

AbstractUrban areas are responsible for a substantial proportion of anthropogenic carbon emissions around the world. As global populations increasingly reside in cities, the role of urban emissions in determining the future trajectory of carbon emissions is magnified. Consequently, a number of research efforts have been started in the United States and beyond, focusing on observing atmospheric carbon dioxide (CO2) and relating its variations to carbon emissions in cities. Because carbon emissions are intimately tied to socioeconomic activity through the combustion of fossil fuels, and many cities are actively adopting emission reduction plans, such urban carbon research efforts give rise to opportunities for stakeholder engagement and guidance on other environmental issues, such as air quality.This paper describes a research effort centered in the Salt Lake City, Utah, metropolitan region, which is the locus for one of the longest-running urban CO2 networks in the world. The Salt Lake City area provides a rich environment for studying anthropogenic emissions and for understanding the relationship between emissions and socioeconomic activity when the CO2 observations are enhanced with a) air quality observations, b) novel mobile observations from platforms on light-rail public transit trains and a news helicopter, c) dense meteorological observations, and d) modeling efforts that include atmospheric simulations and high-resolution emission inventories.Carbon dioxide and other atmospheric observations are presented, along with associated modeling work. Examples in which the work benefited from and contributed to the interests of multiple stakeholders (e.g., policymakers, air quality managers, municipal government, urban planners, industry, and the general public) are discussed.

During 1951 and 1952 a study was conducted on types of larval habitat, larval and adult feeding, cocoon spinning, the emergence process and oviposition of Utah black flies. Most of the work was concentrated at six stations in City Creek Canyon and four stations in Red Butte Canyon. The data obtained at these stations were supplemented with additional observations, made thru 1955, in various localities throughout the state.Red Butte and City Creek Canyons are located on the western side of the Wasatch Mountains. Red Butte Canyon is directly east of Salt Lake City, and City Creek Canyon is approximately three miles northwest of Red Butte and north of the City.

The erection of a State of the Union whose population consisted of Turks or Afghans would not be a worse blunder fraught with more dangerous consequences than the creation of a State composed of Mormons.— C. E. Dutton, an American geologist who surveyed Utah several times during the 1870s.R T. Barnum, the great circus promoter, came to Salt Lake City to meet Brigham Young. The Church President jokingly asked Barnum, “Well, how much money do you think we could make if you were to put me on display back East?” Barnum answered, “Mr. President, I guarantee you half the receipts which will be in excess of $200,000 a year because you would be the greatest show in town.”

The Impact

This research estimates the achievable CO2 emissions reductions for a medium sized office building located in Salt Lake City, Utah. Four strategies that required minor retrofits or changes to a building’s operational controls were considered: automatic window shading, changes in window construction, lighting intensity, and temperature setpoint adjustment. Since 70% of energy consumed by the building sector is for heating, cooling and lighting, the methods introduced were targeted to reduce these sources of demand. The model building used was selected from the U.S. DOE’s commercial reference buildings. The simulations were run using the DOE’s EnergyPlus building energy modeling software and a TMY3 weather data file for Salt Lake City. The effect of these possible building changes on energy consumption and the CO2 emissions resulting from the production of this energy were examined. The impact of the automatic window shade was the lowest of the strategies considered with a 1% reduction in GHG emissions. This is likely the result of a low solar irradiation area to building volume ratio and should be explored for smaller residential and commercial buildings. Window construction was more promising with GHG emissions reductions between 2% and 6%. Lighting strategies and altered temperature set points demonstrated GHG emissions reduction of up to 15%. This research establishes a technique to evaluate building emissions reductions with respect to location, building construction, and operation.
