Hidden Thermal Signatures Reveal The Microclimatic Influence Of Scheduled Cave Tourism, Matt Rowberry, John Gunn, Andrew Smith

International Journal of Speleology

Tourist activity is widely recognised as a source of cave microclimate disturbance, yet visitor-induced variability is difficult to distinguish from natural environmental fluctuations. The coronavirus pandemic created a natural experiment at Poole’s Cavern, United Kingdom, in which periods of complete closure could be compared with contrasting visitor access regimes. Two years of high resolution temperature records from six monitoring points were analysed. Harmonic regression and a state space model removed deterministic diurnal cycles and lower frequency temperature variability. The remaining residual variability differed systematically among visitor access regimes and between daytime and nighttime conditions. Spectral analysis of the residuals identified …

How Water Banking Can Help Refill The Great Salt Lake, Avery Truman, Kendall Becker, Matthew Behrens, Sarah Null, Matt Yost, Scott Hotaling Oct 2026

How Water Banking Can Help Refill The Great Salt Lake, Avery Truman, Kendall Becker, Matthew Behrens, Sarah Null, Matt Yost, Scott Hotaling

All Current Publications

Concern about low water levels in the Great Salt Lake has contributed to the development of water markets in Utah. Water markets enable the voluntary transfer of water or water rights from right holders to other people or entities in exchange for compensation. In general, these transfers are more likely to occur if a water rights holder can make more money by selling their water (or water rights) to another user rather than using it themselves. Willingness to engage in water transfers also depends on the ease of transactions, confidence in the water market, and confidence in the ability to …

"Making The Familiar Strange": The Ecocentric Power Of Climate Fantasy, John Cook Oct 2026

"Making The Familiar Strange": The Ecocentric Power Of Climate Fantasy, John Cook

Mythlore: A Journal of J.R.R. Tolkien, C.S. Lewis, Charles Williams, and Mythopoeic Literature

Contributing to the failure to address climate change is a lack of public imagination, both in perceiving the threat of climate change and conceptualizing solutions. Climate fiction engages readers on an emotional level and speculative fiction in particular can invent alternative worlds illustrating different ways of thinking and living. Fantasy fiction is uniquely suited as a form of climate fiction, with its immersive, subversive qualities, prioritization of the nonhuman, and a tendency towards sprawling, multiple-volume epic series. This paper explores two categories of climate fantasy themes. One category is recovery—regaining a clear view of the natural world. The other is …

Community-Based Well Testing And Outreach To Mitigate Human Health Risk From Unsafe Drinking Water, W. Adam Sigler, Katharine Sutphen, Margaret J Eggers, Kaleena Miller, Michelle Grocke-Dewey

Journal of Extension

Twenty-two percent of groundwater wells tested nationwide have one or more contaminants above a health threshold, yet many private well owners are unaware of these risks because they have not tested their water. Researchers piloted a community well testing clinic for education/outreach and surveyed participants about outcomes. Two months later, 75% of participants with high or intermediate health risk water quality results had taken action or intended to, indicating that community private well testing clinics can be effective in mitigating human health risks from contaminated drinking water.
